Edward Drinker Cope (1840-1897), US palaeontologist. Cope was appointed professor of comparative zoology and botany at Haverford College in 1864, and from 1889 until his death was professor at the University of Pennsylvania. In 1872 he joined the US Geological Survey (USGS). He is credited with the discovery of over 1000 fossil species, and performed valuable work on stratigraphy and the evolutionary origin of horses. In later years, he was involved in a bitter and protracted rivalry with fellow palaeontologist and head of the USGS, Othniel Marsh (1831-1899). This signed photograph is dated 1895.
