I’m planning more posts about the following politically significant figures, about whom little is known in the non-Dutch-reading world. For now, the links to Dutch and English sources (Biografisch Portaal van Nederland and the Global Anabaptist-Mennonite Encyclopedia Online, plus a few others when appropriate) will serve as a start.
