Paul Belloni Du Chaillu (1831 1903) was a French-American traveler, zoologist, and anthropologist. He became famous in the 1860s as the first modern European outsider to confirm the existence of gorillas, and later the Pygmy people of central Africa. He later researched the prehistory of Scandinavia.There are conflicting reports of both the year and place of Du Chaillu's birth. The year is variously given as 1831 (the consensus of modern scholars), 1835, or 1839; the date when given is July 31. Accounts usually cite either Paris or New Orleans as his likely place of birth. A contemporary obituary quotes a statement made by Du Chaillu referring to "the United States, my country by adoption, and ... France, my native land." His entry in the 1901-1902 edition of Marquis Who's Who which was based on information he supplied directly to the editors says 1838 in New Orleans. His grave marker identifies his place of birth as Louisiana, and the year as 1839.
