Francis John Hyde Wollaston FRS (13 April 1762, London – 12 October 1823) was an English natural philosopher and Jacksonian Professor at the University of Cambridge.
Francis John Hyde Wollaston was the son of Francis Wollaston (1731–1815) and Althea Hyde, and brother to William Hyde Wollaston (1766-1828). He was educated in Scarning, Norfolk and at Charterhouse before entering Sidney Sussex College, Cambridge in 1779. He graduated as senior wrangler in 1783, became a fellow of Trinity Hall in 1785, and was ordained a priest in 1787.
Wollaston was elected a Fellow of the Royal Society in 1786.[1] From 1792 to 1813 he was Jacksonian Professor at Cambridge. Resigning his Trinity Hall fellowship to marry Frances Hayles in 1793, he became Rector of South Weald the following year. In 1807 he was elected Master of Sidney Sussex College, but the election was declared invalid on the grounds that he had never been a fellow of Sidney Sussex. On resigning his professorship in 1813, he assumed additional clerical duties: from 1813 to 1823 he was rector of Cold Norton and Archdeacon of Essex.
He is buried with his father in St Nicholas's Churchyard in Chislehurst.
