Yahrtzeit of Rabbi Shlomo Luria (1510-1573), known by the acronym of his name, Maharshal. His ancestry was traced back to the great Jewish commentator, Rashi, and he was a cousin of Rabbi Moshe Isserles, who wrote the Ashkenazi portion of the Code of Jewish Law. Rabbi Luria himself wrote the classic book of Jewish law, Yam Shel Shlomo, and a commentary on the Talmud, Chachmat Shlomo (an abridged version appears in nearly all editions of the Talmud today). He was rabbi of the city of Brisk, and head of the famed Lublin Yeshiva, which attracted students from across Europe.
