founder of the Familists (q.v.). A rich cloth-merchant, he associated with the Anabaptists in Amsterdam. About 1539 he believed that he had Divine communications commanding him to found a new sect, the ‘Family of Love’. In 1540 he went to Emden, where he wrote a number of books, including the Glass of Righteousness; in 1560 the authorities took steps against his sectarian activities and he fled to Kampen, Rotterdam, and finally Cologne. He thought that he would heal the schisms in Christendom, but his books were condemned by Protestants and Catholics alike.
