Abraham Dee Bartlett (27 October 1812–1897) was a British taxidermist and an expert on captive animals. A superintendent of the London Zoo, he was a prominent observer of animal life and was a zoologist.
Abraham was the second son of John Bartlett and Jane Dunster. John Bartlett had apprenticed under William Turner, father of J. M. W. Turner, the famous artist and was a hairdresser and brush maker. Abraham became interested in animals a child and was allowed by his father's friend, Edward Cross, who was in charge of the Royal Menagerie to make regular visits. This interest led to Cross introducing him to taxidermy. He however began to work as an apprentice to his father in the hairdressing business before he shifted to taxidermy in 1834. His taxidermy business near the British Museum was so successful that he was able to move to bigger home and towards the end of his life he owned three houses. He married Lydia Norvall and had four daughters and two sons.
Bartlett supported D. W. Mitchell on the idea that the collection of animals held by the Zoological Society of London could be made accessible to the public for a small fee that could help the Society. It was open on Mondays for a fee of six pence. Queen Victoria gifted him a gold watch for taking care of her pet birds. Dead bird were given to him for taxidermy and for his excellent exhibits, he received a gold medal at the Great Exhibition of 1851. He was among the first to reconstruct a specimen of the dodo and this was displayed Sydenham Crystal Palace where he was also appointed naturalist around 1852. The restoration was however destroyed in the 1866 fire. He associated himself with the Zoological Society and was offered the position of superintendent made vacant by the death of John Thompson at the garden in Regents Park in 1859. As Superintendent, Bartlett became a familiar figure for visiting naturalists and corresponded with many across the world. He was an agent for the acquisition of wild animals from suppliers such as Edward Blyth and was involved in their sale to circus agents such as P.T. Barnum. He kept the position at the zoo until his death and became a familiar figure. He became an authority on the care of wild animals and published papers in the Proceedings of the Zoological Society and other journals. He received a silver medal by the Zoological Society in 1872 and was made an associate of the Linnean Society in 1879. Charles Darwin often discussed his ideas on sexual selection with Bartlett. He noted for instance: "I asked Mr. Bartlett, of the Zoological Gardens, who has had very large experience with birds, whether the male tragopan (one of the Gallinaceae) was polygamous, and I was struck by his answering, 'I do not know, but I should think so from his splendid colours.'" When Darwin was studying the expressions of wild animals he was introduced to the artistic abilities and observation ability of Joseph Wolf by Bartlett.
Bartlett died in the zoo premises on 7 May 1897 after suffering from an illness. He was buried at St James's cemetery, Highgate. His son, Clarence, who had been assistant superintendent at the zoo took his position as superintendent. Another son Edward Bartlett also became a taxidermist who collected specimens in Peru and became a curator at the Maidstone Museum and the Raja Brooke's museum, in Sarawak. Several writings by Bartlett were published after his death in two books, Wild Animals in Captivity (1898) and Life among Wild Beasts in 'the Zoo' (1900).
