 During his visit to Vienna in 1785, Mozart's father Leopold also became a Mason.Mozart's position within the Masonic movement, according to Maynard Solomon, lay with the rationalist, Enlightenment-inspired membership, as opposed to those members oriented toward mysticism and the occult.This rationalist faction is identified by Katharine Thomson as the Illuminati, a masonically inspired group which was founded by Bavarian professor of canon law Adam Weishaupt, who was also a friend of Mozart.
