Evelyn Underhill was one of the premiere authors on mysticism of the twentieth century.
Born in Wolverhampton, England in 1875 to barrister Sir Arthur Underhill and his wife, Evelyn was educated at home and at King's College for Women. In 1907 she married Hubert Stuart Moore, also a barrister. In that year she also underwent an experience of conversion to Christianity. Much of the rest of her life became a quest to find the meaning of her early religious experiences. Throughout the rest of her life she moved from Neoplatonist to Theist to Christocentric Christian.
