J. B. S. Haldane
J. B. S. Haldane, born John Burdon Sanderson Haldane, known as Jack, FRS (/ˈhɔːldeɪn/; 5 November 1892 – 1 December 1964) (but who used 'J. B. S.' in his printed works), was a British scientist, well known for his works in physiology, genetics and evolutionary biology, mathematics where he made innovative contributions to statistics and biostatistics. He was son of the equally famous John Scott Haldane. He was a socialist, Marxist, atheist, and humanist whose political dissent led him to leave England in 1956 and live in India.His first paper in 1915 demonstrated genetic linkage in mammals while subsequent works helped to create population genetics, establishing a unification of Mendelian genetics and Darwinian evolution by natural selection and laying the groundwork for modern evolutionary synthesis. His article on Abiogenesis in 1929 introduced the ""Primordial Soup Theory"", and is the foundation of modern understanding of the chemical origin of life. Haldane established human gene maps for haemophilia and colour blindness on the X chromosome, and formulated Haldane's rule on sterility in the heterogametic sex of hybrids in species. He correctly proposed that sickle-cell disease gives some immunity to malaria. He was the first to suggest the central idea of in vitro fertilisation, as well as concepts such as hydrogen economy, cis trans, coupling, repulsion, darwin (as a unit of evolution) and cloning. In 1957 he articulated Haldane's dilemma, a limit on the speed of beneficial evolution which subsequently proved incorrect. He willed his body for medical studies, as he wanted to remain useful even in death.Arthur C. Clarke credited him as ""perhaps the most brilliant science populariser of his generation"". Nobel laureate Peter Medawar called Haldane ""the cleverest man I ever knew"".
