J. B. S. Haldane

John Burdon Sanderson Haldane, nicknamed "Jack" or "JBS", was a British-born scientist and polymath, and a foundational figure in the modern synthesis of evolutionary biology. He worked in the fields of physiology, genetics, evolutionary biology, and mathematics. With innovative use of statistics in biology, he was one of the founders of neo-Darwinism. Largely self-taught in biology, he held professorships at the University of Cambridge, the Royal Institution, and University College London. Renouncing his British citizenship, he became an Indian citizen in 1961 and worked at the Indian Statistical Institute until his death in 1964.
