Arthur Edward Waite (2 October 1857 – 19 May 1942) was a British poet and scholarly mystic who wrote extensively on occult and esoteric matters, and was the co-creator of the Rider–Waite tarot deck (also called the Rider–Waite–Smith or Waite–Smith deck). As his biographer R. A. Gilbert described him, "Waite's name has survived because he was the first to attempt a systematic study of the history of western occultism—viewed as a spiritual tradition rather than as aspects of proto-science or as the pathology of religion."
