Tosafist of the twelfth century; pupil of Samuel ben Meïr and Jacob Tam. His name occurs in Tos. Giṭ. 8a and 'Ab. Zarah 74b, and in several other places. Peter fell a victim to the persecutions of the second Crusade. While accompanying the body of a parnas, he was assailed by the crusaders and slain. "This," says Ephraim of Bonn, "occurred at ," which place Gross identifies with Carinthia, in Austria. A confusing account of Peter's martyrdom is given by Joseph ha-Kohen, who asserts that it happened at Ramerupt () and that Jacob (Jacob Tam?) was killed together with Peter.
