John Needham

Died 30 Dec 1781 at age 68 (born 10 Sep 1713).John Turberville Needham was an English clergyman and naturalist who was a Roman Catholic priest. He experimented, with Buffon, on the idea of spontaneous generation of life. After boiling mutton broth and sealing it in sealed it in glass containers which were stored for a few days, then reopened, he found numerous microorganisms therein. His conclusion was that the organisms had arisen from non-living matter. (However, two decades later, Spallanzani indicated this was invalid since some spores could still survive the short period of boiling temperature Needham used.) He was the first clergyman of his faith to become a member of the Royal Society of London (1768).
