Rashbam
Samuel ben Meir (Troyes, c. 1085 – c. 1158) after his death known as "Rashbam", a Hebrew acronym for: RAbbi SHmuel Ben Meir, was a leading French Tosafist and grandson of Shlomo Yitzhaki, "Rashi."
Biography
He was born in the vicinity of Troyes, in around 1085 in France to his father Meir ben Shmuel and mother Yocheved, daughter of Rashi. He was the older brother of the Tosafists Isaac ben Meir (the "Rivam") and Jacob ben Meir ("Rabbeinu Tam"), and a colleague of Rabbi Joseph Kara.
Like his maternal grandfather, the Rashbam was a biblical commentator and Talmudist. He learned from Rashi and from Isaac ben Asher ha-Levi ("Riva"). He was the teacher of his brother, Rabbeinu Tam, and his method of interpretation differed from that of his grandfather.
His commentary on the Torah is renowned for its stress on the plain meaning (peshat) of the text. He sometimes disputes his grandfather's interpretation and indicates that his grandfather concurred with his approach. He adopted a natural (as distinct from a homiletical and traditional) method. This approach often led him to state views that were somewhat controversial. Thus Rashbam (on Genesis 1:5) maintained that the day began at dawn and not from the previous sunset (as later Jewish custom assumed). Another famous interpretation was Rashbam's view that the much disputed phrase in Genesis 49:10 must be rendered “Until he cometh to Shiloh,” and refers to the division of the kingdom of Judah after Solomon's death.
