But Rashbam's authority, if not his knowledge, was exceeded by that of his younger brother Jacob. Jacob Tam, born about 1100, was still a very young child when Rashi died. He studied under the guidance of his father, on whose death he assumed the direction of the academy of Rameru in his father's place. Then he went to Troyes, where he was surrounded by numerous pupils, some from countries as distant as Bohemia and Russia. One of his best known disciples was Eliezer ben Samuel, of Metz (died about 1198), author of the <I>Sefer Yereim</I> (Book of the Pious). Other pupils of his mentioned were Moses ben Abraham, of Pontoise, to whom he wrote in particularly affectionate terms, and Jacob of Orleans, a scholar held in high regard, who died at London in 1189 in the riot that broke out the day of Richard I's coronation. A year later, in 1190, the liturgical poet and Biblical commentator Yomtob de Joigny died at York. It seems that Jacob Tam, like his successors, had to suffer from the popular hate and excesses. In fact he tells how, on one occasion, on the second day of Pentecost (possibly at the time of the troubles resulting from the Second Crusade), he was robbed and wounded, and was saved from death only through the intervention of a lord. The end of his life was saddened by the <I>auto-da-fe</I> of Blois, at which numerous Jews suffered martyrdom. He perpetuated the memory of that occasion by instituting a fast day. He died in 1171, universally regretted for his clear and accurate intellect, his piety, uprightness, amiability, and modesty. His contemporaries considered him the highest rabbinical authority, and he was consulted by persons as remote as in the south of France and the north of Spain. He possessed a remarkably original, broad yet subtle intellect, and his writings display keen penetration and singular vigor of thought. He devoted himself chiefly to Biblical exegesis; but in this domain he obtained a reputation less through the purely exegetical parts than through the critical work in which he defended the grammarian Menahem against the attacks of Dunash.[138] His liturgical compositions and the short poems with which he sometimes prefaced his Responsa show that he was a clever poet, an imitator of the Spaniards. Abraham Ibn Ezra while on his rovings in France was one of his correspondents.
