Shimshon ben Tzadok

Rabbi Shimshon ben Tzadok was a primary student of the Maharam of Rothenberg, a prominent 13th-century German scholar and one of the Ba’alei HaTosafot. When his teacher was imprisoned after attempting to flee Germany, Rabbi Shimshon visited him and gathered his teachings into a work called the Tashbetz (often referred to as the Tashbetz Katan to differentiate it from another work by Rabbi Shimon ben Tzamach Duran).
