Edward Drinker Cope

492: 4171: 429:, a small Quaker school where the family had philanthropic ties. The college awarded him an honorary master's degree so he could have the position. Cope even began to think about marriage and consulted his father in the matter, telling him of the girl he would like to marry: "an amiable woman, not over sensitive, with considerable energy, and especially one inclined to be serious and not inclined to frivolity and display—the more truly Christian of course the better—seems to be the most practically the most suitable for me, though intellect and accomplishments have more charm." Cope thought of Annie Pim, a member of the Society of Friends, as less a lover than companion, declaring, "her amiability and domestic qualities generally, her capability of taking care of a house, etc., as well as her steady seriousness weigh far more with me than any of the traits which form the theme of poets!" Cope's family approved of his choice, and the marriage took place in July 1865 at Pim's farmhouse in Chester County, Pennsylvania. The two had a single daughter, Julia Biddle Cope, born June 10, 1866. Cope's return to the United States also marked an expansion of his scientific studies; in 1864, he described several fishes, a whale, and the amphibian 795: 341:, near West Chester, Pennsylvania. The school was founded in 1799 with fundraising by members of the Society of Friends (Quakers), and provided much of the Cope family's education. The prestigious school was expensive, costing Alfred $ 500 in tuition each year, and in his first year, Edward studied algebra, chemistry, scripture, physiology, grammar, astronomy, and Latin. Edward's letters home requesting a larger allowance show he was able to manipulate his father, and he was, according to author and Cope biographer Jane Davidson, "a bit of a spoiled brat". His letters suggest he was lonely at the school—it was the first time he had been away from his home for an extended period. Otherwise, Edward's studies progressed much like a typical boy—he consistently had "less than perfect" or "not quite satisfactory" marks for conduct from his teachers, and did not work hard on his penmanship lessons, which may have contributed to his often-illegible handwriting as an adult. 628:, that had four flippers and a long neck—he commented that the fossil's head was on the wrong end, evidently stating that Cope had put the skull at the end of the vertebrae of the tail. Cope was outraged and the two argued for some time until they agreed to have Leidy examine the bones and determine who was right. Leidy came, picked up the head of the fossil and put it on the other end. Cope was horrified since he had already published a paper on the fossil with the error at the American Philosophical Society. He immediately tried to buy back the copies, but some remained with their buyers (Marsh and Leidy kept theirs). The whole ordeal might have passed easily enough had Leidy not exposed the cover-up at the next society meeting, not to alienate Cope, but only in response to Cope's brief statement where he never admitted he was wrong. Cope and Marsh would never talk to each other amicably again, and by 1873, open hostility had broken out between them. 295: 847:

anyone ... all the sides of his multiform character." Osborn, intending to follow the coffin to the graveyard, was instead pulled aside by Collins and taken to the reading of Cope's will—Osborn and Cope's brother-in-law John Garrett were named executors. Cope gave his family a choice of his books, with the remainder to be sold or donated to the University of Pennsylvania. After debts were handled, Cope left small bequests to friends and family—Anna Brown and Julia received $ 5000 each, while the remainder went to Annie. Cope's estate was valued at $ 75,327, not including additional revenue raised by sales of fossils to the American Museum of Natural History, for a total of $ 84,600. Some specimens preserved in alcohol made their way to the Academy of Natural Sciences, including a few

782:. In the 1890s, his publication rate increased to an average of 43 articles a year. His final expedition to the West took place in 1894, when he prospected for dinosaurs in South Dakota and visited sites in Texas and Oklahoma. The same year, Julia was married to William H. Collins, a Haverford astronomy professor. The couple's ages—Julia was 28 and the groom 35—were past the conventions of Victorian marriage. After their European honeymoon, the couple returned to Haverford. While Annie moved to Haverford, as well, Cope did not. His official reason was the long commute and late lectures he gave in Philadelphia. In private correspondence, however, Osborn wrote that the two had essentially separated, though they remained on amiable terms. 349:. Edward often obtained bad marks due to quarreling and bad conduct. His letters to his father show he chafed at farm work and betrayed flashes of the temper for which he would later become well known. After sending Edward back to the farm for summer break in 1854 and 1855, Alfred did not return Edward to school after spring 1856. Instead, Alfred attempted to turn his son into a gentleman farmer, which he considered a wholesome profession that would yield enough profit to lead a comfortable life, and improve the undersized Edward's health. Until 1863, Cope's letters to his father continually expressed his yearning for a more professional scientific career than that of a farmer, which he called "dreadfully boring". 887: 417:. He held two university degrees in comparison to Edward's lack of formal schooling past 16, but Edward had written 37 scientific papers in comparison to Marsh's two published works. While they would later become rivals, the two men appeared to take a liking to each other upon meeting. Marsh led Edward on a tour of the city, and they stayed together for days. After Edward left Berlin, the two maintained correspondence, exchanging manuscripts, fossils, and photographs. Edward burned many of his journals and letters from Europe upon his return to the United States. Friends intervened and stopped Cope from destroying some of his drawings and notes, in what author Url Lanham deemed a "partial suicide". 930:

doubts about the literalness of the Bible ... he did not express them in his letters to his family but there can be little question ... that he shared the intellectual unrest of the period." Lanham writes that Cope's religious fervor (which seems to have subsided after his father's death) was embarrassing to even his devout Quaker associates. Biographer Jane Davidson believes that Osborn overstated Cope's internal religious conflicts. She ascribes Cope's deference to his father's beliefs as an act of respect or a measure to retain his father's financial support. Frazer's reminiscences about his friend suggest Cope often told people what they wanted to hear, rather than his true views.

635:, a schoolteacher in Golden, Colorado. Lakes had been hiking in the mountains near the town of Morrison with his friend, H. C. Beckwith, looking for fossilized leaves in the Dakota sandstone. Instead, the pair found large bones embedded in the rock. Lakes wrote that the bones were "apparently a vertebra and a humerus bone of some gigantic saurian." While Lakes sent Marsh some 1,500 pounds of bone, he also sent Cope some of the specimens. Marsh published his finds first, and having been paid $ 100 for the finds Lakes wrote to Cope that the samples should be forwarded to Marsh. Cope was offended by the slight. Meanwhile, Cope received bones from school superintendent O.W. Lucas in March 1877 from 33: 717:. Cope visited the mines each summer from 1881 to 1885, taking the opportunity to supervise or collect other minerals. For a while he made good money, but the mines stopped producing and by 1886 he had to give up his now-worthless stocks. The same year he received a teaching position at the University of Pennsylvania. He continued to travel west, but realized he would not be able to best Marsh in cornering the market for bones; he had to release the collectors he had hired and sell his collections. During this period, he published 40 to 75 papers each year. With the failure of his mines, Cope began searching for a job, but was turned down at the Smithsonian and 819:, a substance based on formaldehyde used to preserve specimens. Osborn was horrified by Cope's actions and made arrangements for surgery, but the plans were put on hold after a temporary improvement in Cope's health. Cope went to Virginia looking for fossils, became ill again, and returned to his home very weak. Osborn visited Cope on April 5, inquiring about Cope's health, but the sick paleontologist pressed his friend for his views on the origin of mammals. Word of Cope's illness spread, and he was visited by friends and colleagues; even in a feverish condition Cope delivered lectures from his bed. Cope died on April 12, 1897, 16 weeks short of his 57th birthday. 443:, in part to be closer to the fossil beds of western New Jersey. Due to the time-consuming nature of his Haverford position, Cope had not had time to attend to his farm and had let it out to others, but eventually found he was in need of more money to fuel his scientific habits. Pleading with his father for money to pursue his career, he finally sold the farm in 1869. Alfred apparently did not press his son to continue farming, and Edward focused on his scientific career. He continued his continental travels, including trips to Virginia, Tennessee, and North Carolina. He visited caves across the region. He stopped these cave explorations after an 1871 trip to the 592: 484:(1878), possibly the largest dinosaur ever discovered. In the period of one year, from 1879 to 1880, Cope published 76 papers based on his travels through New Mexico and Colorado, and on the findings of his collectors in Texas, Kansas, Oregon, Colorado, Wyoming, and Utah. During the peak years, Cope published around 25 reports and preliminary observations each year. The hurried publications led to errors in interpretation and naming—many of his scientific names were later canceled or withdrawn. In comparison, Marsh wrote and published less frequently and more succinctly—his works appeared in the widely read 527:. The survey traveled through New Mexico, whose Puerco formations, he wrote to his father, provided "the most important find in geology I have ever made". The New Mexico bluffs contained millions of years of formation and subsequent deformation, and were in an area which had not been visited by Leidy or Marsh. Being part of the survey had other advantages; Cope was able to draw on fort commissaries and defray publishing costs. While there was no salary, his findings would be published in the annual reports the surveys printed. Cope brought Annie and Julia along on one such survey, and rented a house for them at 737:

Marsh and Powell published their own side of the story and, in the end, little changed. No congressional hearing was created to investigate Powell's alleged misallocation of funds, while Cope and Marsh were not held responsible for any mistakes. Indirectly, however, the attacks may have been influential in Marsh's fall from power in the survey. Due to pressure from Powell over bad press, Marsh was removed from his position for the government surveys. Cope's relations with the president of the University of Pennsylvania soured, and the entire funding for paleontology in the government surveys was pulled.

922:: "I have often seen him busily engaged in such comparisons, all the while whistling whole passages from grand opera, or else counting the scales on the back of a lizard, while he conversed in a most amusing manner with some small street urchin who had drifted into the museum and was watching in awe with eyes and mouth wide open." His self-taught nature, however, meant that he was largely hostile to bureaucracy and politics. He had a famous temper; one friend called Cope a "militant paleontologist". Despite his faults, he was generally well liked by his contemporaries. American paleontologist 687: 786:

29,000. While his collection contained more than 13,000 specimens, Cope's fossil hoard was still much smaller than Marsh's collection, valued at over a million dollars. The University of Pennsylvania bought part of Cope's ethnological artifact collection for $ 5,500. The Academy of Natural Sciences, Philadelphia's foremost museum, did not bid on any of Cope's sales due to bad blood between Cope and the museum's leaders; as a result, many of Cope's major finds left the city. Cope's proceeds from the sales allowed him to rehire Sternberg to prospect for fossils on his behalf.

1019:(1884) and "Essays in Evolution". He discovered a total of 56 new dinosaur species during the Bone Wars compared to Marsh's 80. Although Cope is today known as a herpetologist and paleontologist, his contributions extended to ichthyology, in which he cataloged 300 species of fishes and described over 300 species of reptiles over three decades. In total, he discovered and described over 1,000 species of fossil vertebrates and published 600 separate titles. One species of Caribbean snake, 948:, which had little effect on him. The only comment about Darwin's book recorded by Cope was that Darwin discussed "too much geology" from the account of his voyage. Due to his background in taxonomy and paleontology, Cope focused on evolution in terms of changing structure, rather than emphasizing geography and variation within populations as Darwin had. Over his lifetime, Cope's views on evolution shifted. His early views held that while Darwin's 958:

detailing his views on the subject. He was a strong believer in the law of use and disuse—that an individual will slowly, over time, favor an anatomical part of its body so much that it will become stronger and larger as time progresses down the generations. The giraffe, for example, stretched its neck to reach taller trees and passed this acquired characteristic to its offspring in a developmental phase that is added to gestation in the womb.

exhausting slumber." Nevertheless, Cope continued to lead the party from sunrise to sunset, sending letters to his wife and child describing his finds. The severe desert conditions and Cope's habit of overworking himself till he was bedridden caught up with him, and in 1872, he broke down from exhaustion. Cope maintained a regular pattern of summers spent prospecting and winters writing up his findings from 1871 to 1879.

396:, Cope traveled through Europe, taking the opportunity to visit the most esteemed museums and societies of the time. Initially, he seemed interested in helping out at a field hospital, but in letters to his father later on in the war, this aspiration seemed to disappear; instead he considered working in the American South to assist freed African Americans. Davidson suggests Cope's correspondence with Leidy and 215: 544:

collection of fossils. Cope's expeditions took him across Kansas, Colorado, New Mexico, Wyoming, and Montana. His initial journey into the Clarendon beds of Upper Miocene and Lower Pliocene of Texas led to an affiliation with the Geological Survey of Texas. Cope's papers on the region constitute some of his most important paleontological contributions. In 1877, he purchased half the rights to the

1254: 364:, one of the most influential anatomists and paleontologists at the time. Cope asked his father to pay for a tutor in German and French to allow him to read scholarly works in those languages. During this period, he had a job recataloging the herpetological collection at the Academy of Natural Sciences, where he became a member at Leidy's urging. Cope visited the 673:, one of the most recognizable dinosaur recreations of the time. The summer of 1879 took Cope to Salt Lake City, San Francisco, and north to Oregon, where he was amazed at the rich flora and the blueness of the Pacific Ocean. In 1879, the United States Congress consolidated the various government survey teams into the United States Geological Survey with 463:. Marsh accompanied him on one of these excursions. Cope's proximity to the beds after moving to Haddonfield made more frequent trips possible. The Copes lived comfortably in a frame house backed by an apple orchard. Two maids tended the estate, which entertained a number of guests. Cope's only concern was for more money to spend on his scientific work. 400:, who worked as field surgeons during the war, might have informed Cope of the horrors of the occupation. Edward was involved in a love affair; his father did not approve. Whether Edward or the unnamed woman (whom he at one point intended to marry) broke off the relationship is unknown, but he took the breakup poorly. Biographer and paleontologist 318:. The death of his mother when he was three years old seemed to have had little effect on young Edward, as he mentioned in his letters that he had no recollection of her. His stepmother, Rebecca Biddle, filled the maternal role; Cope referred to her warmly, as well as his younger stepbrother, James Biddle Cope. Alfred, an orthodox member of the 902:. She would not comment on the name of the woman with whom her father had had an affair prior to his first European travel. Julia is believed to have burned any of the scandalous letters and journals Cope had kept, but many of his friends were able to give their recollections of the scandalous nature of some of Cope's unpublished routines. 561:, who according to Osborn, "alone treated with coolness". Following the Dublin meeting, Cope spent two days with the French Association for the Advancement of Science. At each gathering, Cope exhibited dinosaur restorations by Philadelphia colleague John A. Ryder and various charts and plates from geological surveys of the 1870s led by 721:. He turned to giving lectures for hire and writing magazine articles. Each year, he lobbied Congress for an appropriation with which to finish his work on "Cope's Bible", a volume on Tertiary vertebrates, but was continually turned down. Rather than work with Powell and the survey, Cope tried to inflame sentiment against them. 651:, to take charge of the digging. Cope, in response, learned of Carlin and Reed's discoveries and sent his own men to find bones in the area. The two scientists attempted to sabotage each other's progress. Cope was described as a genius and what Marsh lacked in intelligence, he easily made up for in connections—Marsh's uncle was 713:, but it drained him of funds. After Hayden was removed from the survey, Cope lost his source of government funding. His fortune was not enough to support his rivalry, so Cope invested in mining. Most of his properties were silver mines in New Mexico; one mine yielded an ore vein worth $ 3 million in 807:. His wife cared for him in Philadelphia when she was able; at other times, Cope's university secretary, Anna Brown, tended to him. Cope at this time lived in his Pine Street museum and rested on a cot surrounded by his fossil finds. Cope often prescribed himself medications, including large amounts of 929:

Cope was raised as a Quaker, and was taught that the Bible was literal truth. Although he never confronted his family about their religious views, Osborn writes that Cope was at least aware of the conflict between his scientific career and his religion.

The Cope family were of English origin; the first to settle in America, in 1683, was Oliver Cope, a tailor formerly of 557:'s Dublin meeting. He was warmly welcomed in England and France, and met with the distinguished paleontologists and archeologists of the period.
