Jump to: navigation, search

Heini (Heinrich) Seiler, an Anabaptist martyr, a hatter of Aarau, Switzerland, who suffered death by drowning at Bern in July 1531 together with Hans Seckler and Hans Dreier. He was one of the eight Anabaptists who had planned to take part in the great religious colloquy of 1528 in Bern but were arrested, tried after the colloquy, and expelled from the city and canton. Seized the second time, Seiler was examined on 24 May 1529, with the two men mentioned above and held prisoner for two years longer. An account of the trial is found in Hansmann, Hans. On 19 April 1531, he had a conversation with Hans Pfistermeyer.
