Paul Belloni Du Chaillu (July 31, 1831 (disputed)April 29, 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. Early life and parentage 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. Edward Clodd, Du Chaillu's friend, told the story differently in his memoirs. Clodd mentioned New York as another claimed location, but asserted that Du Chaillu's true birthplace was the French Indian Ocean island territory of Île Bourbon (now called Réunion). He further claimed that du Chaillu's mother was a mulatto woman. In 1979, historian Henry H. Bucher presented evidence to back Clodd's view, including records of Du Chaillu's father. Bucher argued that Du Chaillu, as a member of the European scientific community, would have tried to obfuscate or conceal the family history that would have labeled him a quadroon. In the 19th century atmosphere of scientific racism, great apes and Sub-Saharan Africans were often considered to both have small cranial capacity, and thus be innately unable to achieve civilization; Du Chaillu's credibility as a scientist and explorer would have suffered as a result. Indeed, comments in a letter by Du Chaillu's contemporary, the ethnologist of Africa Mary Kingsley, indicate that at least some scientists who thought poorly of Du Chaillu knew of his ancestry or other discrediting information about him. In his youth, he accompanied his father, a French trader in the employment of a Parisian firm, to the west coast of Africa where, at a station on the Gabon, he was educated by missionaries and acquired an interest in and knowledge of the country, its natural history,
