Alfred Wallace (1823-1913), British naturalist, with his wife, Mrs T.V. Wallace, his sister Fanny, Mrs Simms. Wallace organised expeditions to the Amazon and Malaysia and was the first European to see orang-utans in the wild. Wallace collected many specimens and founded the study of the geographical distribution of animals (biogeography). He formulated (independent of Charles Darwin) the theory of natural selection as a mechanism for the origin of species. He and Darwin presented their results in a joint paper in 1858 before the Linnean Society. Photograph, taken after Wallace's return from the Amazon, from the Wallace collection in the General Library at the Natural History Museum, London, UK.
