British author Evelyn Underhill died on June 15, 1941 in London, England. She 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 Neo-platonist to Theist to Christ centric. The first book resulting from this interest was Mysticism: A Study in the Nature and Development of Spiritual Consciousness (1911). This book remains the classic in its field. She later wrote numerous other books on mysticism and other topics, including Practical Mysticism.
