Alan Robertson (geneticist)

Alan Robertson (21 February 1920 – 25 April 1989) was an English population geneticist. Originally a chemist, he was recruited after the Second World War to work on animal genetics on behalf of the British government, and continued in this sphere until his retirement in 1985. He was a major influence in the widespread adoption of artificial insemination of cattle.

In addition to his work on agricultural genetics, Robertson undertook extensive studies of other branches of genetics, developing an influential secondary theorem of natural selection. He acquired an international reputation, receiving state and academic honours from Europe, America and Asia.
