Notice en anglais — Sefaria. La traduction française est en préparation.
Yaakov ben Meir (Rabbenu Tam) was a French rabbi, halachic authority, liturgical poet and one of the greatest of the Ba'alei HaTosafot. His renown extended from his native France and Germany to Spain and beyond. In his Tosafot commentary, he often disagrees with the opinion of his grandfather, Rashi. The best known of these disagreements is in regard to the order of the passages contained in the head-worn tefillin, and it continues to impact daily Jewish practice to this day. He narrowly escaped death at the hands of Crusaders. He befriended Ibn Ezra during the latter's stay in France, and they maintained a subsequent correspondence.
