The Allegheny River, left, and Monongahela River join to form the Ohio River at Pittsburgh, Pennsylvania, the largest metropolitan area on the river.

Built between 1849 and 1851, the Wheeling Suspension Bridge was the first bridge across the river.

text: Geography and hydrography[edit]

text: The Ohio River is formed by the confluence of the Allegheny and Monongahela rivers at Point State Park in Pittsburgh, Pennsylvania. From there, it flows northwest through Allegheny and Beaver counties, before making an abrupt turn to the south-southwest at the West Virginia–Ohio–Pennsylvania triple-state line (near East Liverpool, Ohio; Chester, West Virginia; and Midland, Pennsylvania). From there, it forms the border between West Virginia and Ohio, upstream of Wheeling, West Virginia.

text: The river then follows a roughly southwest and then west-northwest course until Cincinnati, before bending to a west-southwest course for most of its length. The course forms the northern borders of West Virginia and Kentucky; and the southern borders of Ohio, Indiana and Illinois, until it joins the Mississippi River near the city of Cairo, Illinois.

text: Geology[edit]

text: From a geological standpoint, the Ohio River is young. The river formed on a piecemeal basis beginning between 2.5 and 3 million years ago. The earliest ice ages occurred at this time and dammed portions of north-flowing rivers. The Teays River was the largest of these rivers. The modern Ohio River flows within segments of the ancient Teays. The ancient rivers were rearranged or consumed by glaciers and lakes.

text: Upper Ohio River[edit]

text: The upper Ohio River formed when one of the glacial lakes overflowed into a south-flowing tributary of the Teays River. Prior to that event, the north-flowing Steubenville River (no longer in existence) ended between New Martinsville and Paden City, West Virginia. Likewise, the south-flowing Marietta River (no longer in existence) ended between the present-day cities. The overflowing lake carved through the separating hill and connected the rivers.

text: The resulting floodwaters enlarged the small Marietta valley to a size more typical of a large river. The new large river subsequently drained glacial lakes and melting glaciers at the end of the Ice Age. The valley grew during and following the ice age.

text: Many small rivers were altered or abandoned after the upper Ohio River formed. Valleys of some abandoned rivers can still be seen on satellite and aerial images of the hills of Ohio and West Virginia between Marietta, Ohio, and Huntington, West Virginia. As testimony to the major changes that occurred, such valleys are found on hilltops.[clarification needed]

text: Middle Ohio River[edit]

text: The middle Ohio River formed in a manner similar to formation of the upper Ohio River. A north-flowing river was temporarily dammed southwest of present-day Louisville, creating a large lake until the dam burst. A new route was carved to the Mississippi. Eventually the upper and middle sections combined to form what is essentially the modern Ohio River.

text: History[edit]

text: Pre-Columbian inhabitants of eastern North America considered the Ohio part of a single river continuing on through the lower Mississippi. The river's name comes from the Seneca (Iroquoian) Ohiːyo', a proper name derived from ohiːyoːh, meaning "good river".[8] The combined Allegheny-Ohio river is 1,310 miles (2,110 km) long and carries the largest volume of water of any tributary of the Mississippi. The Indians and early explorers and settlers of the region also often considered the Allegheny to be part of the Ohio. The forks (the confluence of the Allegheny and Monongahela rivers at what is now Pittsburgh) was considered a strategic military location.

text: French fur traders operated in the area, and France built forts along the Allegheny River. In 1669, René-Robert Cavelier, Sieur de La Salle, led an expedition of French traders who became the first Europeans to see the river. He traveled from Canada and entered the headwaters of the Ohio, traveling as far as the Falls of Ohio at present-day Louisville before turning back. He returned to explore the river again in other expeditions. An Italian cartographer traveling with him created the first map of the Ohio River. La Salle claimed the Ohio Valley for France.

text: In 1749, Great Britain established the Ohio Company to settle and trade in the area. Exploration of the territory and trade with the Indians in the region near the Forks by British colonials from Pennsylvania and Virginia – both of which claimed the territory – led to conflict with the French. In 1763, following the Seven Years' War, France ceded the area to Britain.[9]

text: The 1768 Treaty of Fort Stanwix opened Kentucky to colonial settlement and established the Ohio River as a southern boundary for American Indian territory.[10] In 1774, the Quebec Act restored the land east of the Mississippi River and north of the Ohio River to Quebec, in effect making the Ohio the southern boundary of Canada. This appeased the Canadien British subjects but angered the Thirteen Colonies. Lord Dunmore's War south of the Ohio river also contributed to giving the land north to Quebec to stop further encroachment of the British colonials on native land. During the American Revolution, in 1776 the British military engineer John Montrésor created a map of the river showing the strategic location of Fort Pitt, including specific navigational information about the Ohio River's rapids and tributaries in that area.[11] However, the Treaty of Paris (1783) gave the entire Ohio Valley to the United States.

text: The economic connection of the Ohio Country to the East was significantly increased in 1818 when the National Road being built westward from Cumberland, Maryland reached Wheeling, Virginia (now West Virginia), providing an easier overland connection from the Potomac River to the Ohio River.[12]

text: Louisville was founded at the only major natural navigational barrier on the river, the Falls of the Ohio. The Falls were a series of rapids where the river dropped 26 feet (7.9 m) in a stretch of about 2 miles (3.2 km). In this area, the river flowed over hard, fossil-rich beds of limestone. The first locks on the river – the Louisville and Portland Canal – were built to circumnavigate the falls between 1825 and 1830. Fears that Louisville's transshipment industry would collapse proved ill-founded: the increasing size of steamships and barges on the river meant that the outdated locks could only service the smallest vessels until well after the Civil War. The U.S. Army Corps of Engineers improvements were expanded again in the 1960s, forming the present-day McAlpine Locks and Dam.

text: Because the Ohio River flowed westward, it became a convenient means of westward movement by pioneers traveling from western Pennsylvania. After reaching the mouth of the Ohio, settlers would travel north on the Mississippi River to St. Louis, Missouri. There, some continued on up the Missouri River, some up the Mississippi, and some further west over land routes. In the early 19th century, river pirates such as Samuel Mason, operating out of Cave-In-Rock, Illinois, waylaid travelers on their way down the river. They killed travelers, stealing their goods and scuttling their boats. The folktales about Mike Fink recall the keelboats used for commerce in the early days of European settlement. The Ohio River boatmen were the inspiration for performer Dan Emmett, who in 1843 wrote the song "The Boatman's Dance".

text: Trading boats and ships traveled south on the Mississippi to New Orleans, and sometimes beyond to the Gulf of Mexico and other ports in the Americas and Europe. This provided a much-needed export route for goods from the west, since the trek east over the Appalachian Mountains was long and arduous. The need for access to the port of New Orleans by settlers in the Ohio Valley led to the Louisiana Purchase in 1803.

text: Because the river is the southern border of Ohio, Indiana, and Illinois, it was part of the border between free states and slave states in the years before the American Civil War. The expression "sold down the river" originated as a lament of Upper South slaves, especially from Kentucky, who were shipped via the Ohio and Mississippi to cotton and sugar plantations in the Deep South.[13][14] Before and during the Civil War, the Ohio River was called the "River Jordan" by slaves crossing it to escape to freedom in the North via the Underground Railroad.[15] More escaping slaves, estimated in the thousands, made their perilous journey north to freedom across the Ohio River than anywhere else across the north-south frontier. Harriet Beecher Stowe's Uncle Tom's Cabin, the bestselling novel that fueled abolitionist work, was the best known of the anti-slavery novels that portrayed such escapes across the Ohio. The times have been expressed by 20th-century novelists as well, such as the Nobel Prize-winning Toni Morrison, whose novel Beloved was adapted as a film of the same name. She also composed the libretto for the opera Margaret Garner (2005), based on the life and trial of an enslaved woman who escaped with her family across the river.

text: The Ohio River is considered to separate Midwestern Great Lakes states from the Upper South states, which were historically border states in the Civil War.

text: The colonial charter for Virginia defined its territory as extending to the north shore of the Ohio, so that the riverbed was "owned" by Virginia. Where the river serves as a boundary between states today, Congress designated the entire river to belong to the states on the east and south, i.e., West Virginia and Kentucky at the time of admission to the Union, that were divided from Virginia. Thus Wheeling Island, the largest inhabited island in the Ohio River, belongs to West Virginia, although it is closer to the Ohio shore than to the West Virginia shore. Kentucky brought suit against Indiana in the early 1980s because of the building of the Marble Hill nuclear power plant in Indiana, which would have discharged its waste water into the river.

text: The U.S. Supreme Court held that Kentucky's jurisdiction (and, implicitly, that of West Virginia) extended only to the low-water mark of 1793 (important because the river has been extensively dammed for navigation, so that the present river bank is north of the old low-water mark.) Similarly, in the 1990s, Kentucky challenged Illinois' right to collect taxes on a riverboat casino docked in Metropolis, citing its own control of the entire river. A private casino riverboat that docked in Evansville, Indiana, on the Ohio River opened about the same time. Although such boats cruised on the Ohio River in an oval pattern up and down, the state of Kentucky soon protested. Other states had to limit their cruises to going forwards, then reversing and going backwards on the Indiana shore only. Since 2002, Indiana has allowed its riverboat casinos to be permanently docked.

text: In the early 1980s, the Falls of the Ohio National Wildlife Conservation Area was established at Clarksville, Indiana.

text: Pollution[edit]

text: The Ohio River as a whole is ranked as the most polluted river in the US based on 2009 and 2010 data although the more industrial and regional Ohio tributary, Monongahela River, ranked behind 16 other American rivers for pollution at number 17.[16]

text: The Ohio River was polluted with hundreds of thousands of pounds of PFOA by DuPont chemical company, from an outflow pipe, for several decades beginning in the 1950s.[17]

text: River depth[edit]

text: The Ohio River is a naturally shallow river that was artificially deepened by a series of dams. The natural depth of the river varied from about 3 to 20 feet (0.91 to 6.10 m). The dams raise the water level and have turned the river largely into a series of reservoirs, eliminating shallow stretches and allowing for commercial navigation. From its origin to Cincinnati, the average depth is approximately 15 feet (5 m). The largest immediate drop in water level is below the McAlpine Locks and Dam at the Falls of the Ohio at Louisville, Kentucky, where flood stage is reached when the water reaches 23 feet (7 m) on the lower gauge. However, the river's deepest point is 168 feet (51 m) on the western side of Louisville, Kentucky. From Louisville, the river loses depth very gradually until its confluence with the Mississippi at Cairo, Illinois, where it has an approximate depth of 19 feet (6 m).

text: Water levels for the Ohio River from Smithland Lock and Dam upstream to Pittsburgh are predicted daily by the National Oceanic and Atmospheric Administration's Ohio River Forecast Center.[18] The water depth predictions are relative to each local flood plain based upon predicted rainfall in the Ohio River basin in five reports as follows:

text:
Pittsburgh, Pennsylvania, to Hannibal Locks and Dam, Ohio (including the Allegheny and Monongahela rivers)
Willow Island Locks and Dam, Ohio, to Greenup Lock and Dam, Kentucky (including the Kanawha River)
Portsmouth, Ohio, to Markland Locks and Dam, Kentucky
McAlpine Locks and Dam, Kentucky, to Cannelton Locks and Dam, Indiana
Newburgh Lock and Dam, Indiana, to Golconda, Illinois

text: When Calls the Heart

text: Plot[edit]

text: When Calls the Heart tells the story of Elizabeth Thatcher (Erin Krakow), a young teacher accustomed to her high-society life. She receives her first classroom assignment in Coal Valley, a small coal-mining town in Western Canada which is located just south of Robb, Alberta. There, life is simple—but often fraught with challenges. Elizabeth charms most everyone in Coal Valley, except Royal North West Mounted Police Constable Jack Thornton (Daniel Lissing). He believes Thatcher’s wealthy father has doomed the lawman's career by insisting he be assigned in town to protect the shipping magnate’s daughter. The town of Coal Valley was renamed Hope Valley in Episode 2, Season 2 after the coal mine was closed.

text: Living in this 1910 coal town, Elizabeth must learn the ways of the Canadian frontier movement if she wishes to thrive in the rural west on her own. Lori Loughlin portrays Abigail Stanton, whose husband, the foreman of the mine, and her only son—along with 44 other miners—have recently been killed in an explosion, which turns out to have been a tragic accident waiting to happen—a result of the mining-company site manager's irresponsible management and lack of due care in his management of the mine. The newly widowed women find their faith tested when they must go to work in the mine to keep a roof over their heads, food on the table, and compile a wage for the town's teacher.[8]

text: Characters[edit]

text:
Elizabeth Thatcher is an independent, strong-minded, passionate and dedicated young teacher from the city. The middle daughter of William and Grace Thatcher, Elizabeth has two sisters, older sister Viola and younger sister Julie. Elizabeth finds herself in Coal Valley, a small community on the Canadian frontier in need of a teacher, and quickly discovers it is not an easy place to live, lacking the creature comforts and luxuries of her privileged life with her family. She soon meets the newly appointed and charismatic Mountie Jack Thornton and develops an immediate dislike for him. However, over time they become good friends, and develop an obvious attraction to one another. In the final episode of season 1, "Prelude to a Kiss," (also titled as "Final Adieu"), after overcoming many obstacles throughout the season, Jack tells Elizabeth, "You're the one, you're the only one" and they share a kiss. Throughout season 2, Elizabeth's feelings for Jack are high at times as well as low. Finally, in the season 2 finale, she admits that his job as a Mountie scares her. After being comforted both admitting that they love each other, Jack and Elizabeth kiss.
Jack Thornton is a laid back country boy. Jack is the son of Mountie Thomas Thornton and his wife Charlotte Thornton. Jack has a younger brother, Tom (named after his father). As a Mountie and a man of stout character and integrity, he often finds himself protecting and saving people. In season 1's "A Telling Silence," Jack finds a basset hound whom he names Rip (after Rip Van Winkle) and takes home with him. A source of comfort and companion in the small town, Jack often goes to Rip when times in his life are difficult. In season 2's "With All My Heart," Rip, who's afraid of thunder, hides in the mine shafts during a storm. Jack and Elizabeth search for him; in their search, their relationship grows stronger. Upon his first meeting of Elizabeth, he developed an instant dislike and it appeared she irritated him. However, he grew to like and then fall madly and completely in love with her over time. In "Rules of Engagement" (S.1), it is revealed that Jack was briefly engaged to Rosemary LeVeaux when she comes looking for him. However, they have both changed and realize that they cannot have a relationship as they once did ever again. In "Prelude to a Kiss" (S.1), Jack found out that Elizabeth may be leaving Coal Valley. Taking her on a walk and giving her a framed picture of them that he had sketched, he asks her not to leave Coal Valley and tells her, "You're the one, you're the only one." She replied that she was "not going anywhere", Coal Valley was where she belonged before they share a kiss. In season 2, Elizabeth and Jack share a hot-and-cold relationship until the finale, "With All My Heart." They both admit that they love each other and share another kiss. Jack's brother, Tom, is introduced season 2's "Trials of the Heart," and their rocky relationship continues until "Coming Together, Coming Apart." Jack gently reminds his younger brother how their father was so proud of him, but he wouldn't be proud of the way he was currently living. Both in tears, Jack tells his younger brother that he believes in him and that he can turn his life around. More recently, Jack has become good friends with the sawmill operator, Lee Coulter. In season 3, Jack begins the new year knowing that Elizabeth only has eyes for him and that her relationship with Charles is over for good. In "Hearts In Question," Jack's mother Charlotte shows up unexpectedly. She meets Elizabeth and is suspicious of her, but through staying her sees Elizabeth for who she really is: a trustworthy, dedicated teacher. In the season finale, "Prayers From The Heart," Jack is injured in a landslide. But he miraculously recovers in time to serve as Lee's best man at his wedding.
Abigail Stanton is a Coal Valley woman who tragically lost her husband and son in the mining accident. Abigail is a very kind woman, and she stands strongly for the things she believes in. She is one of the first women to welcome Elizabeth and the two women quickly become friends. When Elizabeth accidentally burns down the little teacherage, Abigail gladly welcomes her into her home to live. After being complimented on her cooking, Abigail decides to open a cafe in Coal Valley. Together, Abigail and Elizabeth move into the rooms above the cafe. At the end of season 1, Abigail enjoys the company of Bill Avery, a Mountie, serving as a Forensic Investigator and friend of Jack Thornton's. In season 2, Abigail takes in her daughter-in-law, Clara, the wife of her late son Peter whom Abigail sees as the daughter she never had. With Bill's past being revealed, Abigail ends their friendship and spends more time with the new pastor, Frank Hogan. Also, she is a strong independent woman that is set on doing the things that are right and tries to help Elizabeth.
Bill Avery is a mysterious, quiet man. He first appears in season 1's "Rules of Engagement," in order to help Jack expose Mr. Gowen's wrongdoings. Bill is immediately attracted to widow Abigail Stanton. Things are going well until Abigail discovers a picture of Bill's family and his wedding ring. He later tells her that his son died, as well as his wife. However, his wife, Nora, comes to confront him in season 2's "Heart's Desire."
Henry Gowen is a cold, cynical man who formerly owned the coal mine. After the mine was shut down, Henry became the mayor of Hope Valley and still creates a cold, cynical presence whenever people are around him. Henry is highly disliked and feared in the town. He frequently uses bribery to get what he wants, which is never for the good of the town.
Rosemary "Rosie" LeVeaux is a flamboyant, enthusiastic actress from New York. She was briefly engaged to Jack Thornton, but they both realized that it wouldn't work out. Rosie immediately disliked Elizabeth and viewed her as "the competition," but eventually came to really care about Elizabeth, even if she has a hard time showing it. At the beginning of season 2, Rosemary began working at the cafe with Abigail and the two quickly became friends. Spending time with Abigail helped tone down some of Rosemary's enthusiasm and made her a more likable person. Rosemary even came to like Elizabeth, even if only on an acquaintance level. Truthfully, she cares about everyone in Hope Valley, especially Lee, with whom she shares an mutual attraction. When Rosie is not spending time with Lee, talking to Abigail, or dreaming about the glamorous life of an actress, she can often be found somewhere writing her weekly advice column for Hope Valley's newspaper! In season 3, Rosemary's friendship with Elizabeth deepened. Instead of viewing her as an adversary, she finds a friend in Elizabeth. Throughout season 3, Rosemary's relationship with Lee becomes more romantic. In "Heart Of A Hero," seeing that Lee needs to spend more time at the sawmill to help the new settlers find jobs, Rosemary tells Lee that the theatre doesn't have to be built. He insists, but she says how important his job is. He smiles and tells her he will one day build her theatre, telling her that she is "the best part of his life." The couple shares in their first kiss. In "A Gentle Heart," Lee is injured. Thinking he is asleep, Rosemary pours out her heart to him, telling how much she loves him. In "Heartbreak," Rosemary is offered a job in Hollywood filming. This has always been Rosemary's dream, to be an actress. Lee unselfishly tells her to do whatever she feels best, but it is obvious that the thought of her leaving Hope Valley hurts him. Rosemary considers her options and realizes that her place is in Hope Valley, with Lee. Lee then tells her that he has another "role" that he thinks would be perfect for her and proposes marriage. She happily accepts. In "Hearts In Question," Rosemary enthusiastically plans for their wedding. The couple weds in the season 3 finale "Prayers From The Heart," with Elizabeth and Abigail as her maids of honor.
Leland "Lee" Coulter is a kind, laidback, patient man who opens a sawmill in Hope Valley. When timber becomes Coal Valley's major source of natural resources, the town is renamed Hope Valley. He shares a mutual attraction to Rosemary and proves to be one of the few people who can outwit her. When she declines his romantic intentions, Lee recruits his friend, Molly Sullivan, to make Rosemary jealous; the ploy succeeds and Rosemary accepts his suit, appreciating Lee's good qualities. Despite her dramatic and occasionally prickly personality, Lee's compassion and patience never fails with her. With Rosemary's help, Lee beat Mr. Gowen at his own game in "Heart and Home." When not at work, Lee enjoys being with friends, including Jack Thornton, who shares Lee's simple and laidback outlook, allowing the men to discuss their lives and exchange romantic advice. In season 3, Lee's mill is unfortunately sabotaged by a man inside. Through Bill and Jack's investigation, they find the culprit. In season 3's "Heart Of A Hero," Rosemary unselfishly gives up the theatre that Lee promised to build her. Lee promises that one day, he will build her the theatre at a time when he isn't so involved with the sawmill and finding people jobs. In "A Gentle Heart," Lee is injured. Thinking Lee is asleep, Rosemary pours out her heart to Lee, telling him how afraid she was when she heard he had been injured. He however hears each and every word. She told him how much she loves him and to never leave her. In the episode "Heartbreak," Lee thinks Rosemary may leave Hope Valley when she is offered a movie job in Hollywood. When she gives up the movie, seeing her future in Hope Valley with him, he asks her to marry him. The couple weds in the season 3 finale, "Prayers From The Heart." Jack serves the role of Lee's best man.
Julie Thatcher is Elizabeth's hopeless romantic younger sister. She often gets herself into sticky situations by falling head over heels for men who aren't quite what they seem. In season 2 she gets involved with Jack's brother Tom, which causes trouble with her family and for Jack and Elizabeth's relationship.
Cat Montgomery is a kind, encouraging woman in Coal Valley. She is a widow and mother of three: Gabe, Miles, and Emily. Cat was one of the first mothers to show kindness to Elizabeth when she first came. She desperately wants her children to remember the good memories of their father as seen by her self-sacrificing acts in "Secrets and Lies." Possessing a great sense of teamwork and encouragement, Cat supports the women of Coal Valley while working in the mines in "Cease and Desist." She is good friends with Elizabeth and Abigail. In "These Games," she also helps Jack catch a thief.
Florence Blakeley is a feisty gossip in Hope Valley. She often has a pessimistic perspective and always seems to find the negative, even in a very positive situation. In "Heart and Home," Abigail told Florence what she really thought about her, which causes Florence to rein in her negativity somewhat, though she remains fairly outspoken. While not always likable, Florence adds spice to life in Hope Valley.
Molly Sullivan is a friend of Lee Coulter and Elizabeth Thatcher. Molly's husband was killed in the mine disaster. She has a daughter Rosaleen. In season 1's "A Telling Silence," Rosaleen has trouble in school because she misses her father so much. When she runs away, Elizabeth finds her in the mine, feeling guilty that she didn't bring her father his lunch the day of the disaster because she wanted to play with a friend instead. She fears her mother will blame her, but Elizabeth convinces her that Molly will "say that she loves her more than life itself." Molly is reunited with her daughter, to the joy of the town's people. In season 2's "With All My Heart," Lee feels it's time to "play hard to get" with Rosemary, so he enlists help from Molly. She pretends to be interested in him romantically. This ploy works and Rosemary admits that she does in fact like him. Molly is a kind woman and was among the first to welcome Elizabeth to town.
Clara Stanton is the wife of Abigail's late son Peter, and is a sweet, quiet, and sensitive young woman. Abigail never knew she had a daughter-in-law until season 2's "Trials of the Heart;" with Peter having married Clara only three days before he was killed. In "Heart's Desire," Abigail invites Clara to come live with her in Hope Valley, an offer that Clara accepts.
Charles Kensington III is an old friend of Elizabeth with whom she reconnects while in Hamilton. He is interested in her, though her feelings for Jack get in the way of their relationship.

text: History of the camera

text: Camera obscura

text: The forerunner to the photographic camera was the camera obscura. Camera obscura (Latin for "dark room") is the natural optical phenomenon that occurs when an image of a scene at the other side of a screen (or for instance a wall) is projected through a small hole in that screen and forms an inverted image (left to right and upside down) on a surface opposite to the opening. The oldest known record of this principle is a description by Han Chinese philosopher Mozi (ca. 470 to ca. 391 BC). Mozi correctly asserted that the camera obscura image is inverted because light travels in straight lines from its source. In the 11th century Arab physicist Ibn al-Haytham (Alhazen)'s wrote very influential books about optics, including experiments with light through a small opening in a darkened room.

text: The use of a lens in the opening of a wall or closed window shutter of a darkened room to project images used as a drawing aid has been traced back to circa 1550. Since the late 17th century portable camera obscura devices in tents and boxes were used as a drawing aid.

text: Before the invention of photographic processes there was no way to preserve the images produced by these cameras apart from manually tracing them. The earliest cameras were room-sized, with space for one or more people inside; these gradually evolved into more and more compact models. By Niépce's time portable box camerae obscurae suitable for photography were readily available. The first camera that was small and portable enough to be practical for photography was envisioned by Johann Zahn in 1685, though it would be almost 150 years before such an application was possible.

text: Early fixed images

text: The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce,[1][2] using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. No means of removing the remaining unaffected silver chloride was known to Niépce, so the photograph was not permanent, eventually becoming entirely darkened by the overall exposure to light necessary for viewing it. In the mid-1820s, Niépce used a sliding wooden box camera made by Parisian opticians Charles and Vincent Chevalier to experiment with photography on surfaces thinly coated with Bitumen of Judea.[3] The bitumen slowly hardened in the brightest areas of the image. The unhardened bitumen was then dissolved away. One of those photographs has survived.

text: Daguerreotypes and calotypes

text: After Niépce's death in 1833, his partner Louis Daguerre continued to experiment and by 1837 had created the first practical photographic process, which he named the daguerreotype and publicly unveiled in 1839.[4] Daguerre treated a silver-plated sheet of copper with iodine vapor to give it a coating of light-sensitive silver iodide. After exposure in the camera, the image was developed by mercury vapor and fixed with a strong solution of ordinary salt (sodium chloride). Henry Fox Talbot perfected a different process, the calotype, in 1840. As commercialized, both processes used very simple cameras consisting of two nested boxes. The rear box had a removable ground glass screen and could slide in and out to adjust the focus. After focusing, the ground glass was replaced with a light-tight holder containing the sensitized plate or paper and the lens was capped. Then the photographer opened the front cover of the holder, uncapped the lens, and counted off as many minutes as the lighting conditions seemed to require before replacing the cap and closing the holder. Despite this mechanical simplicity, high-quality achromatic lenses were standard.[5]

text: Dry plates

text: Collodion dry plates had been available since 1857, thanks to the work of Désiré van Monckhoven, but it was not until the invention of the gelatin dry plate in 1871 by Richard Leach Maddox that the wet plate process could be rivaled in quality and speed. The 1878 discovery that heat-ripening a gelatin emulsion greatly increased its sensitivity finally made so-called "instantaneous" snapshot exposures practical. For the first time, a tripod or other support was no longer an absolute necessity. With daylight and a fast plate or film, a small camera could be hand-held while taking the picture. The ranks of amateur photographers swelled and informal "candid" portraits became popular. There was a proliferation of camera designs, from single- and twin-lens reflexes to large and bulky field cameras, simple box cameras, and even "detective cameras" disguised as pocket watches, hats, or other objects.

text: The short exposure times that made candid photography possible also necessitated another innovation, the mechanical shutter. The very first shutters were separate accessories, though built-in shutters were common by the end of the 19th century.[5]

text: Kodak and the birth of film

text: The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1888-1889. His first camera, which he called the "Kodak," was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came pre-loaded with enough film for 100 exposures and needed to be sent back to the factory for processing and reloading when the roll was finished. By the end of the 19th century Eastman had expanded his lineup to several models including both box and folding cameras.

text: In 1900, Eastman took mass-market photography one step further with the Brownie, a simple and very inexpensive box camera that introduced the concept of the snapshot. The Brownie was extremely popular and various models remained on sale until the 1960s.

text: Film also allowed the movie camera to develop from an expensive toy to a practical commercial tool.

text: Despite the advances in low-cost photography made possible by Eastman, plate cameras still offered higher-quality prints and remained popular well into the 20th century. To compete with rollfilm cameras, which offered a larger number of exposures per loading, many inexpensive plate cameras from this era were equipped with magazines to hold several plates at once. Special backs for plate cameras allowing them to use film packs or rollfilm were also available, as were backs that enabled rollfilm cameras to use plates.

text: Except for a few special types such as Schmidt cameras, most professional astrographs continued to use plates until the end of the 20th century when electronic photography replaced them.

text: 35 mm

text: A number of manufacturers started to use 35mm film for still photography between 1905 and 1913. The first 35mm cameras available to the public, and reaching significant numbers in sales were the Tourist Multiple, in 1913, and the Simplex, in 1914.[citation needed]

text: Oskar Barnack, who was in charge of research and development at Leitz, decided to investigate using 35 mm cine film for still cameras while attempting to build a compact camera capable of making high-quality enlargements. He built his prototype 35 mm camera (Ur-Leica) around 1913, though further development was delayed for several years by World War I. It wasn't until after World War I that Leica commercialized their first 35mm Cameras. Leitz test-marketed the design between 1923 and 1924, receiving enough positive feedback that the camera was put into production as the Leica I (for Leitz camera) in 1925. The Leica's immediate popularity spawned a number of competitors, most notably the Contax (introduced in 1932), and cemented the position of 35 mm as the format of choice for high-end compact cameras.

text: Kodak got into the market with the Retina I in 1934, which introduced the 135 cartridge used in all modern 35 mm cameras. Although the Retina was comparatively inexpensive, 35 mm cameras were still out of reach for most people and rollfilm remained the format of choice for mass-market cameras. This changed in 1936 with the introduction of the inexpensive Argus A and to an even greater extent in 1939 with the arrival of the immensely popular Argus C3. Although the cheapest cameras still used rollfilm, 35 mm film had come to dominate the market by the time the C3 was discontinued in 1966.

text: The fledgling Japanese camera industry began to take off in 1936 with the Canon 35 mm rangefinder, an improved version of the 1933 Kwanon prototype. Japanese cameras would begin to become popular in the West after Korean War veterans and soldiers stationed in Japan brought them back to the United States and elsewhere.

text: TLRs and SLRs

text: The first practical reflex camera was the Franke & Heidecke Rolleiflex medium format TLR of 1928. Though both single- and twin-lens reflex cameras had been available for decades, they were too bulky to achieve much popularity. The Rolleiflex, however, was sufficiently compact to achieve widespread popularity and the medium-format TLR design became popular for both high- and low-end cameras.

text: A similar revolution in SLR design began in 1933 with the introduction of the Ihagee Exakta, a compact SLR which used 127 rollfilm. This was followed three years later by the first Western SLR to use 135 film, the Kine Exakta (World's first true 35mm SLR was Soviet "Sport" camera, marketed several months before Kine Exakta, though "Sport" used its own film cartridge). The 35mm SLR design gained immediate popularity and there was an explosion of new models and innovative features after World War II. There were also a few 35mm TLRs, the best-known of which was the Contaflex of 1935, but for the most part these met with little success.

text: The first major post-war SLR innovation was the eye-level viewfinder, which first appeared on the Hungarian Duflex in 1947 and was refined in 1948 with the Contax S, the first camera to use a pentaprism. Prior to this, all SLRs were equipped with waist-level focusing screens. The Duflex was also the first SLR with an instant-return mirror, which prevented the viewfinder from being blacked out after each exposure. This same time period also saw the introduction of the Hasselblad 1600F, which set the standard for medium format SLRs for decades.

text: In 1952 the Asahi Optical Company (which later became well known for its Pentax cameras) introduced the first Japanese SLR using 135 film, the Asahiflex. Several other Japanese camera makers also entered the SLR market in the 1950s, including Canon, Yashica, and Nikon. Nikon's entry, the Nikon F, had a full line of interchangeable components and accessories and is generally regarded as the first Japanese system camera. It was the F, along with the earlier S series of rangefinder cameras, that helped establish Nikon's reputation as a maker of professional-quality equipment.

text: Instant cameras

text: While conventional cameras were becoming more refined and sophisticated, an entirely new type of camera appeared on the market in 1948. This was the Polaroid Model 95, the world's first viable instant-picture camera. Known as a Land Camera after its inventor, Edwin Land, the Model 95 used a patented chemical process to produce finished positive prints from the exposed negatives in under a minute. The Land Camera caught on despite its relatively high price and the Polaroid lineup had expanded to dozens of models by the 1960s. The first Polaroid camera aimed at the popular market, the Model 20 Swinger of 1965, was a huge success and remains one of the top-selling cameras of all time.

text: Automation

text: The first camera to feature automatic exposure was the selenium light meter-equipped, fully automatic Super Kodak Six-20 pack of 1938, but its extremely high price (for the time) of $225 ($3828 in present terms[6]) kept it from achieving any degree of success. By the 1960s, however, low-cost electronic components were commonplace and cameras equipped with light meters and automatic exposure systems became increasingly widespread.

text: The next technological advance came in 1960, when the German Mec 16 SB subminiature became the first camera to place the light meter behind the lens for more accurate metering. However, through-the-lens metering ultimately became a feature more commonly found on SLRs than other types of camera; the first SLR equipped with a TTL system was the Topcon RE Super of 1962.

text: Digital cameras

text: Digital cameras differ from their analog predecessors primarily in that they do not use film, but capture and save photographs on digital memory cards or internal storage instead. Their low operating costs have relegated chemical cameras to niche markets. Digital cameras now include wireless communication capabilities (for example Wi-Fi or Bluetooth) to transfer, print or share photos, and are commonly found on mobile phones.

text: Early development

text: The concept of digitizing images on scanners, and the concept of digitizing video signals, predate the concept of making still pictures by digitizing signals from an array of discrete sensor elements. Early spy satellites used the extremely complex and expensive method of de-orbit and airborne retrieval of film canisters. Technology was pushed to skip these steps through the use of in-satellite developing and electronic scanning of the film for direct transmission to the ground. The amount of film was still a major limitation, and this was overcome and greatly simplified by the push to develop an electronic image capturing array that could be used instead of film. The first electronic imaging satellite was the KH-11 launched by the NRO in late 1976. It had a charge-coupled device (CCD) array with a resolution of 800 x 800 pixels (0.64 megapixels).[7] At Philips Labs in New York, Edward Stupp, Pieter Cath and Zsolt Szilagyi filed for a patent on "All Solid State Radiation Imagers" on 6 September 1968 and constructed a flat-screen target for receiving and storing an optical image on a matrix composed of an array of photodiodes connected to a capacitor to form an array of two terminal devices connected in rows and columns. Their US patent was granted on 10 November 1970.[8] Texas Instruments engineer Willis Adcock designed a filmless camera that was not digital and applied for a patent in 1972, but it is not known whether it was ever built.[9] The Cromemco CYCLOPS introduced as a hobbyist construction project in 1975[10] was the first digital camera to be interfaced to a microcomputer.

text: The first recorded attempt at building a self-contained digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak.[11][12] It used the then-new solid-state CCD image sensor chips developed by Fairchild Semiconductor in 1973.[13] The camera weighed 8 pounds (3.6 kg), recorded black and white images to a compact cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.

text: Analog electronic cameras

text: Handheld electronic cameras, in the sense of a device meant to be carried and used like a handheld film camera, appeared in 1981 with the demonstration of the Sony Mavica (Magnetic Video Camera). This is not to be confused with the later cameras by Sony that also bore the Mavica name. This was an analog camera, in that it recorded pixel signals continuously, as videotape machines did, without converting them to discrete levels; it recorded television-like signals to a 2 × 2 inch "video floppy".[14] In essence it was a video movie camera that recorded single frames, 50 per disk in field mode and 25 per disk in frame mode. The image quality was considered equal to that of then-current televisions.

text: Analog electronic cameras do not appear to have reached the market until 1986 with the Canon RC-701. Canon demonstrated a prototype of this model at the 1984 Summer Olympics, printing the images in the Yomiuri Shinbun, a Japanese newspaper. In the United States, the first publication to use these cameras for real reportage was USA Today, in its coverage of World Series baseball. Several factors held back the widespread adoption of analog cameras; the cost (upwards of $20,000), poor image quality compared to film, and the lack of quality affordable printers. Capturing and printing an image originally required access to equipment such as a frame grabber, which was beyond the reach of the average consumer. The "video floppy" disks later had several reader devices available for viewing on a screen, but were never standardized as a computer drive.

text: The early adopters tended to be in the news media, where the cost was negated by the utility and the ability to transmit images by telephone lines. The poor image quality was offset by the low resolution of newspaper graphics. This capability to transmit images without a satellite link was useful during the Tiananmen Square protests of 1989 and the first Gulf War in 1991.

text: US government agencies also took a strong interest in the still video concept, notably the US Navy for use as a real time air-to-sea surveillance system.

text: The first analog electronic camera marketed to consumers may have been the Casio VS-101 in 1987. A notable analog camera produced the same year was the Nikon QV-1000C, designed as a press camera and not offered for sale to general users, which sold only a few hundred units. It recorded images in greyscale, and the quality in newspaper print was equal to film cameras. In appearance it closely resembled a modern digital single-lens reflex camera. Images were stored on video floppy disks.

text: Silicon Film, a proposed digital sensor cartridge for film cameras that would allow 35 mm cameras to take digital photographs without modification was announced in late 1998. Silicon Film was to work like a roll of 35 mm film, with a 1.3 megapixel sensor behind the lens and a battery and storage unit fitting in the film holder in the camera. The product, which was never released, became increasingly obsolete due to improvements in digital camera technology and affordability. Silicon Films' parent company filed for bankruptcy in 2001.[15]

text: Arrival of true digital cameras

text: By the late 1980s, the technology required to produce truly commercial digital cameras existed. The first true portable digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 2 MB SRAM memory card that used a battery to keep the data in memory. This camera was never marketed to the public.

text: The first digital camera of any kind ever sold commercially was possibly the MegaVision Tessera in 1987 [16] though there is not extensive documentation of its sale known. The first portable digital camera that was actually marketed commercially was sold in December 1989 in Japan, the DS-X by Fuji[17] The first commercially available portable digital camera in the United States was the Dycam Model 1, first shipped in November 1990.[18] It was originally a commercial failure because it was black and white, low in resolution, and cost nearly $1,000 (about $2000 in 2014).[19] It later saw modest success when it was re-sold as the Logitech Fotoman in 1992. It used a CCD image sensor, stored pictures digitally, and connected directly to a computer for download.[20][21][22]

text: In 1991, Kodak brought to market the Kodak DCS (Kodak Digital Camera System), the beginning of a long line of professional Kodak DCS SLR cameras that were based in part on film bodies, often Nikons. It used a 1.3 megapixel sensor, had a bulky external digital storage system and was priced at $13,000. At the arrival of the Kodak DCS-200, the Kodak DCS was dubbed Kodak DCS-100.

text: The move to digital formats was helped by the formation of the first JPEG and MPEG standards in 1988, which allowed image and video files to be compressed for storage. The first consumer camera with a liquid crystal display on the back was the Casio QV-10 developed by a team led by Hiroyuki Suetaka in 1995. The first camera to use CompactFlash was the Kodak DC-25 in 1996.[citation needed]. The first camera that offered the ability to record video clips may have been the Ricoh RDC-1 in 1995.

text: In 1995 Minolta introduced the RD-175, which was based on the Minolta 500si SLR with a splitter and three independent CCDs. This combination delivered 1.75M pixels. The benefit of using an SLR base was the ability to use any existing Minolta AF mount lens. 1999 saw the introduction of the Nikon D1, a 2.74 megapixel camera that was the first digital SLR developed entirely from the ground up by a major manufacturer, and at a cost of under $6,000 at introduction was affordable by professional photographers and high-end consumers. This camera also used Nikon F-mount lenses, which meant film photographers could use many of the same lenses they already owned.

text: Digital camera sales continued to flourish, driven by technology advances. The digital market segmented into different categories, Compact Digital Still Cameras, Bridge Cameras, Mirrorless Compacts and Digital SLRs. One of the major technology advances was the development of CMOS sensors, which helped drive sensor costs low enough to enable the widespread adoption of camera phones.

text: Since 2003, digital cameras have outsold film cameras[23] and Kodak announced in January 2004 that they would no longer sell Kodak-branded film cameras in the developed world[24] - and 2012 filed for bankruptcy after struggling to adapt to the changing industry.[25] Smartphones now routinely include high resolution digital cameras.

text: Mark Greene

text: Early life[edit]

text: Mark Greene, an only child, was raised by his mother, Ruth, and father, David. David Greene served in the United States Navy, and thus the family moved frequently and lived all over the country, including: Jacksonville, Florida, Norfolk, Virginia, Corpus Christi, Texas, Washington D.C.,[1] Kings Bay, Georgia,[2] and Hawaii, where they spent three years, David's longest assignment.[3] Mark had a very strained relationship with his father, and was decidedly closer to his mother. He would often act out in an attempt to upset his father, and aimed his goals in the opposite of what his father wanted. Mark thought his father's Navy career mattered more to him than his family, only to later learn that David was on track to be an Admiral and turned down the chance in order to come home and help Mark with a bully. The most memorable time of his childhood was when his family was in Hawaii, a time he would later recreate with daughter Rachel during the last few weeks of his life.

text: While still in high school, Mark met and soon after developed a romantic relationship with Jennifer (Jen). Presumably their relationship lasted the duration of their time in college, and at some point around the time Greene was at medical school, he married Jennifer. His daughter, Rachel was born shortly afterwards. While in medical school, he met future colleague Peter Benton. He then completed his internship and residency in the Emergency Department of County General Hospital in Chicago, Illinois, from there he was awarded the position of Chief Resident of the Emergency Department. While there, Mark developed close friendships with Dr. Doug Ross, a pediatrician, Dr. Susan Lewis, an ER resident, and nurse manager, Carol Hathaway. Although Mark enjoys working the ER, the many nights on call, and the long hours, in addition to Jen's decision to complete law school, have strained their marriage.

text: History[edit]

text: In the pilot episode, which takes place on St. Patrick's Day 1994, Dr. Greene is awakened in the first scene to help his long-time friend Doug, the ER resident who often comes in to sober up on his nights off. Also, his close friendship with Susan is shown as they confide in each other about their personal lives while on break. During the same episode, Jen gets Mark to visit a private practice near the hospital to explore the possibility of leaving his job at the ER and get more family-friendly hours. Mark decides the "clean" medicine isn't his cup of tea. Back at the ER, Mark removes a hangnail from an older woman, who wanted him to remove it despite the fact she'd be charged $180. Later during the night, Mark has to urge everyone to get back to work when Carol is rushed into the ER after a shocking suicide attempt.

text: During the first season, Dr. Greene's marriage becomes increasingly shaky. When offered an attending physician's position by David Morgenstern, Mark readily accepts, much to Jen's chagrin. As a newly admitted member of the bar, Jen has been clerking for a judge in Milwaukee, and becomes increasingly tired of commuting and living separately to accommodate Mark's job. She begins an affair with a coworker, and the marriage soon ends, with Rachel and Jen leaving Chicago first for Milwaukee and later for St. Louis.

text: In "Love's Labor Lost", Mark makes miscalculations in treating a pregnant woman that lead to her death in childbirth, and the after-effects of this case linger long into Season 2.

text: In "A Miracle Happens Here", a Christmas episode, Mark explains that he is the son of an agnostic Jew and a lapsed Catholic. He lights a Hanukkah candle for a Holocaust survivor.[4] Mark understands some Yiddish.[5]

text: Mark's career becomes more difficult as he needs to make decisions that periodically alienate his friends, such as selecting Dr. Kerry Weaver for Chief Resident over another applicant, which angers Susan Lewis because the other applicant is a good friend of hers and because she bristles under Kerry's demanding, sometimes harsh leadership style. Mark's friendship with Dr. Ross becomes strained as his administrative tasks often put him at odds with Doug's wild ways and he is disgusted by Doug's personal problems to the point where he briefly overrules and belittles Doug's abilities as a physician before reconciling with his friend. His love life takes a more drastic downward spin when his feelings for Dr. Lewis increase, but she leaves the hospital for a job in Phoenix, Arizona. He suffers emotionally again after he is attacked in the ER men's room in the episode "Random Acts". The attack is initially believed to be retaliatory act to avenge the death of a patient who may have been "mistreated" by Dr. Greene because of the patient's race. Later, though, it is strongly implied that his assailant was a psychotic individual who was randomly attacking doctors. Mark buys a gun and uses it to scare a crowd of punks on a train but tosses the gun in the river soon afterwards. He struggles through a large part of Season 4 but comes to terms with his attack in Season 5 when he helps Nigerian-born janitor Mobilage Ekabo reveal his memories of torture by talking about the attack with him, allowing him to obtain political asylum and avoid deportation.

text: With the passing of Doug's father comes the re-entrance of Mark's parents. He and Doug travel to California to settle Doug's father's affairs (Doug's father and new wife were both killed in a car wreck) and take a side trip to visit Mark's parents, who live in another part of California. His relationship with his father David is still strained, and his mother suffers from a string of medical conditions associated with aging. Mark also finds out that his mother viewed his birth as a mistake, as she didn't know his father well and got married quickly when she got pregnant. Mark's distrust of the Navy puts him at odds with David when he and Mark fight over whether Ruth should be treated in a base hospital or a civilian hospital. Ruth eventually dies and Mark goes to her funeral, leaving him on edge when he clashes with Kerry Weaver over Robert Romano's successful drive for the chief of staff position.

text: Mark's personal life after his marriage is tumultuous. He takes after Doug, having several flings and an affair with Nurse Chuny Marquez, and setting up three dates in one day. He has a brief relationship with a needy desk clerk, Cynthia Hooper (played by Mariska Hargitay in season 4). Hooper leaves him after she finds out Mark doesn't really love her. Mark eventually meets a British surgeon, Elizabeth Corday. Corday is in Chicago on an exchange program, under the guidance of Dr. Romano. Romano's advances on Corday fail, as does her relationship with Peter Benton. Eventually, Mark and Elizabeth begin dating in Season 5, finally forming a stable and happy relationship. During Season 6, Mark discovers that his father is suffering from advanced lung cancer. After David loses his wife and develops end stage lung cancer, he realises that he can no longer live alone, and he moves to Chicago and stays with Mark; after an awkward first meeting, he warms up to Elizabeth very quickly. After an emotional bonding that heals their difficult relationship from Mark's youth, David dies.

text: Mark and Elizabeth begin a more serious relationship and move in together. Mark later buys a house, and he and Elizabeth get married and have a daughter, Ella. Their happiness is threatened, though, when the abusive father of a patient goes on a killing rampage after losing his son to social workers. In a bid to get his son back, he kills and injures a number of people and attempts to go after Elizabeth and Ella. After being shot by an armed bystander, he is brought to the ER. During his treatment, Mark takes him aboard an elevator to go to an operating room. The patient goes into arrest when alone in the elevator with Mark, who withholds defibrillation and allows him to go into vfib and die. He later falsifies records to show that he did attempt to save the patient. Elizabeth suspects what Mark did but lets the matter drop. Later, Rachel appears in Chicago unannounced, citing arguments with her mother, and moves in with Mark and a very reluctant Elizabeth. She sneaks out of the house at night and uses drugs, which clouds her relationship with Elizabeth.

text: Death[edit]

text: While suturing a patient's wound, Mark loses control of his faculties and is temporarily unable to speak. After a CT scan and a biopsy, he is diagnosed with an aggressive form of brain cancer, glioblastoma multiforme, that is thought to be inoperable. Embarrassed, Greene briefly tries to hide his condition, but his cover is blown when he has a seizure while arguing with Carter. With little time, Mark seeks a second opinion from an eminent New York City neurosurgeon, Dr. Burke. Mark is told that the tumor is near a critical section of his brain but hasn't "invaded" it yet and they can perform an operation on New Year's Eve 2000. Mark's surgery is performed by Burke and things appear to be positive, although it takes him a while to return to his old self. A year or so later, however, Mark finds out his tumor has returned, and Dr. Burke both confirms this and says he cannot operate again because the tumor regrowth is now in part of his brain where an operation would render Mark completely vegetative. While chemo treatment will only allow Mark to live for another 5–6 months, Burke points out: "You should have been dead a year ago, Mark. You got married, saw your daughter be born - I'd say that was time well spent."

text: At this point, Rachel has run away from Jenn in St. Louis and is staying with Mark and Elizabeth. Though she vehemently denies it, her recreational drug use becomes apparent when her baby sister Ella gets hold of some ecstasy in her backpack and nearly dies after ingesting it in the episode "Damage is Done". When Rachel shows up, Mark can barely control his anger at her, berating her for repeatedly lying to him and for putting Ella in danger. However, he sees her remorse and fear for Ella are genuine; knowing Elizabeth is angry enough for both of them, he hugs Rachel when she starts to cry. When Mark refuses to throw Rachel out of the house, Elizabeth says she won't return home with Ella as long as Rachel is there and leaves home with Ella and moves into a hotel. Unwilling to tell Elizabeth about his condition, Mark stays with Susan during the course of his chemotherapy and radiation treatments. Elizabeth later finds out the truth and wants to come home, but Mark tells her she shouldn't pretend to be his wife just because he's sick; however, she returns anyway and begins helping Mark as his terminal illness advances.

text: Eventually, however, he resigns himself to his fate and decides to halt the debilitating chemo, deciding he would rather have three good final months than twice that suffering from his treatments. On his last day in the ER, he meets with the same older woman that viewers saw on the first episode of ER. She again has a hangnail, and complains about how painful it is. Mark tells her that he has an inoperable tumor, asks another doctor to treat her, and tells the patient not to return to the ER again. He leaves the ER, stops his chemotherapy treatments, tells John Carter that he will now "set the tone" and takes Rachel on a last-minute trip to Hawaii to rebuild his relationship with her and relive happier times.

text: After several moves around the island and some conflict with a surly Rachel, Mark suffers from increased symptoms, prompting Rachel to call Elizabeth, who comes to Hawaii with Ella. One night, Rachel comes to her father's room while he sleeps. Mark awakens and smiles at Rachel, telling her with slurred speech that he was just dreaming of her and how she used to love balloons. He tells her that he was trying to think of a piece of advice that every father should tell his daughter, and tells her to be generous with her time, her love, and her life. Rachel tells her father that she remembers a lullaby that Mark used to sing her when she was a baby and slips a pair of headphones on his head and plays Israel Kamakawiwo'ole's rendition of "Over The Rainbow" for him as he smiles and falls back asleep. While the song plays, he is seen walking through an empty ER. The next morning, Elizabeth discovers that he has died.

text: In the episode "The Letter," Carter discovers two faxes that had arrived earlier, both sent by Elizabeth. He reads the first one to the staff. It is a letter that Mark had written about his sentiments about the Chicago County ER where he had worked for many years, and the staff he had worked with throughout the years. They begin happily discussing his letter until someone notices that Carter is holding the second fax, visibly upset. He informs them that the second is a brief letter written by Elizabeth, notifying them that Mark had died that morning around 6 A.M., "… at sunrise, his favorite time of the day." She explains that she sent the first letter to show the staff at the ER what he thought of them. As the staff responds sadly to this news, Frank asks if he should post the second fax on the staff bulletin board, and Carter tells him to post both of them. The letter and the news of his passing sends many of the ER's staff that day into emotional turmoil, with Kerry Weaver going from second-guessing Abby's posting of the letter (she quickly changes her mind and says it should stay up) to crying and stating her regrets to Sandy Lopez that she's lost a friend. This portion of the episode closely models the scene at the end of the film Mister Roberts, when Jack Lemmon's character, Ensign Pulver, reads two similar letters connected with the title character's death. It was also revealed in the episode by Susan Lewis that he died at the age of 38, making his birth year 1964. At the close of the episode, as the staff rush out to the ambulance bay to handle incoming casualties, the wind blowing through the open door tears one page of Mark's letter off the bulletin board.

text: Mark's body is returned to Chicago, where he is buried. Many of his friends and colleagues come to the funeral: John Carter, Peter Benton, Kerry Weaver, Abby Lockhart, Luka Kovač, Susan Lewis, Jing-Mei Chen, Robert Romano, Jerry Markovic, Lydia Wright, Frank Martin, Donald Anspaugh, William "Wild Willy" Swift (played by Michael Ironside in 1994), Haleh Adams, Michael Gallant, Cleo Finch, Jen, Rachel, Ella, and Elizabeth. After the funeral, Rachel asks Elizabeth if she can visit to see Ella; Elizabeth responds "Of course, she's your sister." Rachel then suddenly asks the driver to pull over: she walks to a bunch of balloons attached to a fence, takes a purple one and slowly lets go of it, watching it rise toward the sky. Rachel goes back to living with her mother in St. Louis, but later returns to Chicago when the time comes to select a college, as well as asking a bemused Elizabeth to help her acquire effective birth control pills. In the April 2009 ER series finale, she returns to County General to interview for a spot as a med student, showing that she has become a responsible young woman and followed in Mark's footsteps.

text: Epilogue[edit]

text: Dr. Mark Greene was written out of the series because actor Anthony Edwards had decided that he wanted to move on to other opportunities. Greene was shown in an old Christmas photo in Season 10's "Freefall," alongside Abby and Drs. Lewis, Carter, and Kovac. He also appears in photos included in the slideshow shown at Dr. Carter's farewell party in the Season 11 episode "The Show Must Go On". Greene was also heard in a voice-over telling Carter that he needed to "set the tone" in the ER (which, incidentally, was what Dr. Morgenstern told Dr. Greene in the pilot episode). In the Season 12 episode "Body and Soul," he is mentioned during a flashback to 2002, when Dr. Pratt tells his patient, Nate Lennox (James Woods), that the reason the ER has few staff working is because they are at Greene's funeral. In Season 14's "Blackout," Nurse Chuny Marquez says that she can't believe the ER is going to be led by Pratt and Morris and says how she remembers when Mark Greene and Doug Ross used to run the place. Nurse Sam Taggart then says, "Who?", since she started working in the ER long after they had left.

text: In 2008, ER producers announced that Edwards would reprise his role for the series' final season, with Dr. Greene appearing in flashbacks in the episode "Heal Thyself" shedding light on Dr. Catherine Banfield's (played by Angela Bassett) past.

text: On November 13, 2008, over 6 years after his exit from the show, Anthony Edwards returned as Dr. Mark Greene. The flashback episode took place in 2002, just months before Greene's death and revealed an encounter he had with Catherine Banfield, 6 years before she began working in that same emergency room. He was treating Banfield's son Darryl who had a debilitating disease which turned out to be leukemia. The story appeared to take place at the point in Season 8 when Mark and Elizabeth were reconciling after she learned his tumor had recurred. Mark takes on the mysterious case to save the 5 year old. He has a run-in with Kerry Weaver and Robert Romano about putting this case ahead of his chemo treatment which took a toll on him throughout that day. Darryl dies in the ER but it was Mark's heroic actions that triggered Catherine in the present day to help save a young girl from drowning, and may have also inspired her to work full-time at County. During their encounter, Cate kept pressing Mark, who told her to stop being a doctor and to start being a mother. Cate gave the same advice to the young girl's mother.

text: In the season 15 episode The Book of Abby, long-serving nurse Haleh Adams shows the departing Abby Lockhart a closet wall where all the past doctors and employees have put their locker name tags. Among them, the tag "Greene" can be seen.
