Justus Velsius

Justus Velsius, Haganus, or ''Joost Welsens'' in Dutch (c. 1510, The Hague, Low Countries|group=notes}} – after 1581 at an unknown location), was a Dutch humanist, physician, and mathematician.

Velsius started his career as a highly respected professor of liberal arts in Leuven, Strasbourg, and Cologne. Later on he portrayed himself as a prophet, and promoted his own particular view of Christianity, outlined in a pamphlet "Christiani Hominis Norma" which he wrote in London. He came into conflict with civil and ecclesiastical authorities all over Europe, and spent his final years as a preacher and faith healer in his native Holland. While in Cologne Velsius was married to Beatrix van Steenhoven, and later on, in Groningen, to Grete Cassens. Provided by Wikipedia
