1040 BACHYA IBN PAKUDA (Saragossa, Spain)

1040 - 1105 (29 Tamuz 4865) SOLOMON BEN ISAAC (Troyes, France)
Better known as Rashi. He had studied under the students of Rabbenu Gershom and at the age of 25 became the rabbi in Troyes. Rashi is renowned for his illuminating and succinct commentaries on the Bible and the Talmud, which are still considered indispensable by both Jewish and Christian scholars. Rashi did not hesitate to comment "I don't understand" on Biblical passages which he found perplexing and often paraphrased the words in his native French. His sons-in-law (known as the Tosafists - see 1100) continued with his commentaries, further helping to explain difficult portions of the Talmud. During the First Crusade in 1095-1099, many of Rashi's relatives and friends perished, and some of his manuscripts were destroyed or lost.
