Johann Adam Weishaupt was a German philosopher and founder of the Order of Illuminati (later frequently referred to as the Bavarian Illuminati).
He graduated from the University of Ingolstadt in 1768.
In 1774 he was initiated as a Freemason, but he was not satisfied by the organisation of this order, so on May 1, 1776 he founded his own. This organization was first known as "The Order of Perfectibilists" but became famous as the "Ordo Illuminati Bavarensis".
