1185 RABBI ISAAC BEN SAMUEL (The Elder, aka the Ri) (France)
Dampierre, France. A nephew of both Rabbenu Tam and the Rashbam and a great-grandson of Rashi. He was appointed head of the school at Rumerau after the death of Rabbenu Tam, where 60 of the most renowned scholars studied. The Ri became one of the greatest Tosafists, renowned for his commentary on the Rif. He ruled that since the penalty for emigration was confiscation of property, no Jew had the right to buy confiscated goods. If such goods were purchased, they had to be returned to their owner.
