Founder of the sect of Adrianists; born at Dordrecht, 1524; died at Bruges, 1581. We know nothing of his personal history, and very little concerning the short-lived sect to which he gave his name. The Adrianists, who were mostly women, professed in general the doctrines of the Anabaptists; but what their specific beliefs were cannot be ascertained. Charges of immorality have been named against them, but have never been proved.
