Thomas Raymond Kelly (June 4, 1893 – January 17, 1941) was an American Quaker educator. He taught and wrote on the subject of mysticism. His books are widely read, especially by people interested in spirituality. Kelly was born in 1893 in Chillicothe, Ohio to a Quaker family (members of the Religious Society of Friends). The branch of Quakerism in which he was raised (Wilmington Yearly Meeting) had been influenced by the 19th century revivalists and worship services were similar to other low-church Protestant groups.
