Joseph Léonce "Jo" Di Mambro (19 August 1924 – 5 October 1994) was a French cult leader and convicted conman who founded and lead the Order of the Solar Temple with Luc Jouret. Di Mambro had been associated with a variety of esoteric groups before founding OTS. After the cult began to face increasing public and legal pressures, he died in a mass suicide with other cult members in October 1994. While Jouret was considered by the public to be the figurehead of the group, Di Mambro was the true head of the organization.
