(1492, Siegelsbach, near Heilbronn – 1446, Bergzabern), matriculated at Heidelberg in 1510 and became a pastor in Flinsbach in 1519. In 1520 he received his master’s degree. From 1524 on he was a clergyman and Latin teacher in Bergzabern. Having sided with the Swiss in the Eucharistic controversy (Eucharist: II, 3), he came increasingly under M. Bucer’s influence, especially after conflict with the Anabaptists (meeting with H. Denck in 1527).
