Seth Pancoast

Seth Pancoast (July 28, 1823 - December 16, 1889) was an American homeopathic physician, chromopathist, and occultist, a founding member of the Theosophical Society noted for his authorship of an early English language book on the Kabbala. Pancoast was involved in search efforts for the sunken British sloop of war De Braak (HMS Braak) in 1877, founding the International Submarine Company and mounting a failed two-month attempt to uncover the wreck and the treasures it was-then thought to contain.
