J. B. S. (John Burdon Sanderson) Haldane

Born in Oxford in 1892, J. B. S. Haldane was a British scientist whose work ranged across genetics, physiology, biochemistry, and evolutionary theory. He is widely remembered as one of the key founders of population genetics, helping show how Darwin's ideas about natural selection could be expressed mathematically.

He also became famous as a gifted popularizer of science. Alongside his research, he wrote essays and books that brought big scientific questions to general readers in a lively, direct way. Britannica notes that he opened new paths in population genetics and evolution, while his wider career included teaching, research, and public debate on science and society.

Later in life, Haldane moved to India, where he continued his scientific work until his death in Bhubaneswar in 1964. His legacy lives on both in modern biology and in the tradition of clear, adventurous science writing.
