Rashi is an acronym for Rabbi Shlomo ben Yitzchak (Solomon, son of Isaac), also written as Rabbi Shlomo Yitzchaki. He was born February 22, 1040, and died July 17, 1105. Rashi is one of Judaism's classical meforshim (Bible and Talmud commentators). Rashi wrote the first comprehensive commentaries on the Tanakh (the Bible) and Talmud.
Rashi was born at Troyes, Champagne, northern France, in 1040. Some sources give his surname as Yarchi, indicating that his family came from Lunel (Yareach, in Hebrew). He was reputedly descended from the Davidic line, with lineage to the royal house of King David.
He studied at Worms under Yaakov ben Yakar, and at Mainz under Isaac ben Judah. He returned to Troyes at age 25, probably serving as Rabbi. About 1070, he founded a yeshiva which attracted many disciples. According to tradition, Rashi earned his living as a vintner. There are many stories about his travels, but Rashi's travels probably didn't go beyond than from the Seine to the Rhine, to the Yeshivot of Lorraine. Rashi died in Troyes in 1105.
Rashi had no sons, but three daughters, Yocheved, Miriam and Rachel, all of whom married scholars. Yocheved married Meir ben Samuel, Miriam married Judah ben Nathan, and Rachel married (and divorced) Eliezer ben Shemiah. Yocheved and Meir's four sons were the tosafists Shmuel (Rashbam), Yaakov (Rabbeinu Tam), Yitzchak (Ribbam), and the grammarian Shlomo. One of their daughters, Channah, wrote a responsum explaining the ritual and blessing for the Shabbat lights.
