Charles Webster Leadbeater was a former Anglican minister and a clairvoyant who joined the Theosophical Society. He became Presiding Catholic Bishop of the Society. He was a prolific writer of many occult and paranormal books and pamphlets, and one of the most famous is "Man, Visible and Invisible".

Originally published in 1903, "Man, Visible and Invisible" is an esoteric classic that examines the invisible bodies of humans, showing how the colours of the aura change with different emotional states.
