Johann Sebastian Pfauser

Johann Sebastian Pfauser (c. 1520–1569), probably born at Constance, was a Lutheran theologian who became court preacher to Emperor Maximilian II in Vienna. Under his influence Maximilian read Protestant literature and refused communion under the Catholic rite, though he never formally converted.

Pfauser was in contact with Heinrich Bullinger in Zurich and faced Petrus Canisius in public disputations. Later superintendent at Lauingen in Swabia, he died there on 6 June 1569.
