William John Ansorge


William John Ansorge was a physician who worked in Angola and Uganda and is known for exploring the fauna of the African region. A large number of species have been named after him based on the specimens that he collected and sent back to England.

Life and work

Ansorge's ancestors came from Silesia, but William was born in Chapra, Bengal, to Rev. Paul Gotthold Ansorge in 1850 and studied at the Royal College in Mauritius and then at Pembroke College, Cambridge. He worked briefly at St Bartholomew's Hospital in London. He then became a professor at the Royal College in Mauritius and senior professor from 1880 to 1886. He was posted as a medical officer in Uganda from 1895 to 1898. He was also District Medical Officer in Uganda and Southern Nigeria. He travelled across Africa and wrote Under the African Sun in 1899. Ernst Hartert noted that Ansorge was a very valuable collector and contributor to the bird collection of Walter Rothschild at Tring. Hartert noted that Ansorge's knowledge of the species collected was limited and that he lacked training in zoology. His early collections made from 1892 in Uganda were of poor quality after which he received training from Hartert. Hartert notes that he died in Luanda, Angola at just 64, although appearing much older with his white beard.
Ansorge married Mary Matilda, daughter of G.E. Ely of Edinburgh, in 1881. They had two sons and a daughter. He received two medals with clasps for his service in Uganda 1897–1898 and for his role in the Aro Expedition of 1901–1902.
