J. B. S. Haldane
John Burdon Sanderson Haldane, FRS was a Britishborn Indian scientist known for his work in the study of physiology, genetics, evolutionary biology, and in mathematics, where he made innovative contributions to the fields of statistics and biostatistics. He was the son of the equally famous John Scott Haldane and a professed socialist, Marxist, atheist, and humanist whose political dissent led him to leave England in 1956 and live in India, becoming a naturalised Indian citizen in 1961.
Haldane was born in Oxford to John Scott Haldane, a physiologist, scientist, a philosopher and a Liberal, and Louisa Kathleen Trotter, a Conservative. His younger sister, Naomi Mitchison, became a writer, while his uncle was Viscount Haldane and his aunt the author Elizabeth Haldane. Descended from an aristocratic and secular family of the Clan Haldane, he would later claim that his Y chromosome could be traced back to Robert the Bruce.
