Input: Question: What year did Edward Clodd die? Passage:However, the most reliable information comes from the memoirs of his personal friend Edward Clodd. 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 his 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 linked as sharing a small cranial capacity and an inborn inability to achieve civilization. Du Chaillu's credibility as an African explorer and gorilla expert would have suffered due to his black heritage 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.
