J.B.S. Haldane

J. B. S. Haldane, in full John Burdon Sanderson Haldane (born Nov. 5, 1892, Oxford, Oxfordshire, Eng.—died Dec. 1, 1964, Bhubaneswar, India), British geneticist, biometrician, physiologist, and popularizer of science who opened new paths of research in population genetics and evolution.

Son of the noted physiologist John Scott Haldane, he began studying science as assistant to his father at the age of eight and later received formal education in the classics at Eton College and at New College, Oxford (M.A., 1914). After World War I he served as a fellow of New College and then taught at the University of Cambridge (1922–32), the University of California, Berkeley (1932), and the University of London (1933–57).

In the 1930s Haldane became a Marxist. He joined the British Communist Party and assumed editorship of the party’s London paper, the Daily Worker. Later, he became disillusioned with the official party line and with the rise of the controversial Soviet biologist Trofim D. Lysenko. In 1957 Haldane moved to India, where he took citizenship and headed the government Genetics and Biometry Laboratory in Orissa.

Haldane, R.A. Fisher, and Sewall Wright, in separate mathematical arguments based on analyses of mutation rates, population size, patterns of reproduction, and other factors, related Darwinian evolutionary theory and Gregor Mendel’s concepts of heredity. Haldane also contributed to the theory of enzyme action and to studies in human physiology. He possessed a combination of analytic powers, literary abilities, a wide range of knowledge, and a force of personality that produced numerous discoveries in several scientific fields and proved stimulating to an entire generation of research workers.


“There is no great invention, from fire to flying, which has not been hailed as an insult to some god.”

“It seems to me immensely unlikely that mind is a mere by-product of matter. For if my mental processes are determined wholly by the motions of atoms in my brain I have no reason to suppose that my beliefs are true. They may be sound chemically, but that does not make them sound logically. And hence I have no reason for supposing my brain to be composed of atoms.”

“If one could conclude as to the nature of the Creator from a study of creation it would appear that God has an inordinate fondness for stars and beetles.”
