George Whitefield (December 16, 1714 – September 30, 1770), was a preacher in the Church of England and one of the leaders of the Methodist movement. He first took to preaching in the open air on Hanham Mount, Kingswood, in southeast Bristol. A crowd of 20,000 people gathered to hear him. Even larger crowds – Whitefield himself estimated 30,000 – met him in Cambuslang in 1742. Benjamin Franklin once attended a revival meeting in Philadelphia and was greatly impressed with Whitefield's ability to deliver a message to such a large audience.
