JBS Haldane and the X-Craft
John Burdon Sanderson Haldane FRS (/ˈhɔːldeɪn/; 5 November 1892 – 1 December 1964[1][2]), nicknamed "Jack" or "JBS",[3] was a British-Indian scientist who worked in physiology, genetics, evolutionary biology, and mathematics. With innovative use of statistics in biology, he was one of the founders of neo-Darwinism. Despite his lack of an academic degree in the field,[1] he taught biology at the University of Cambridge, the Royal Institution, and University College London.[4] Renouncing his British citizenship, he became an Indian citizen in 1961 and worked at the Indian Statistical Institute for the rest of his life.
