Heaven's Gate was an American new religious movement known primarily for the mass suicides of its members in 1997. Often described as a cult, it was founded in 1974 and led by Marshall Applewhite (1931–1997) and Bonnie Nettles (1927–1985), known within the movement as Do and Ti, respectively. Nettles and Applewhite first met in 1972 and went on a journey of spiritual discovery, identifying themselves as the two witnesses of the Book of Revelation, attracting a following of several hundred people in the mid-1970s. In 1976, a core group of a few dozen members stopped recruiting and instituted a monastic lifestyle.
