Wheatstone, Sir Charles (1802–1875), British physicist. Wheatstone was professor of experimental philosophy at King's College, London. He is remembered for his researches in electricity, sound, and light. In 1834 he devised a revolving mirror for an experiment to measure the speed of electricity in a conductor. In 1843 he constructed the Wheatstone bridge and began to popularize its use. He initiated the use of electromagnets in electric generators, and in 1837 he and Sir William Fothergill Cooke patented an early telegraph.
