Rashi

Shlomo Yitzhaki (Hebrew: רבי שלמה יצחקי‎), or in Latin Salomon Isaacides, and today generally known by the acronym Rashi (Hebrew: רש"י‎, RAbbi SHlomo Itzhaki; February 22, 1040 – July 13, 1105), was a medieval French rabbi and long highly esteemed as a major contribution Ashkenazi Jewry gave to Torah study. He is famed as the author of a comprehensive commentary on the Talmud, as well as a comprehensive commentary on the Tanakh (Hebrew Bible). He is considered the "father" of all commentaries that followed on the Talmud (i.e., the Baalei Tosafot) and the Tanakh (i.e., Ramban, Ibn Ezra, Ohr HaChaim, et al.).
