He was educated at Balliol College, Oxford, and served in the Royal Artillery in the Second World War in India, Burma and Sumatra, reaching the rank of captain.

He then commenced a distinguished academic career, and was one of the founding fathers of the faculty of chemistry at the Weizmann Institute of Science.

Late in his career, his scientific interests moved from physical chemistry (particularly chemical kinetics) to neurobiology.
