Yahrtzeit of Rabbi Yosef Karo (1488-1575), author of Shulchan Aruch, the standard Code of Jewish Law. Rabbi Karo was forced to flee Spain at the time of the expulsion, eventually settling in the holy city of Tzfat, Israel. His writings in Jewish law include Beit Yosef, an encyclopedic commentary on the Tur (written and refined over 30 years), and Kesef Mishneh, a commentary on Maimonides' Mishneh Torah. Yet Rabbi Karo is best known for his Shulchan Aruch, which covers the gamut of practical Jewish law; almost all Jewish legal discussions to this day stem from this code. Rabbi Karo also had kabbalistic leanings (he was a contemporary in Tzfat of the great Arizal) and he authored a book, Maggid Mesharim, in which he records his discussions with an angel. Rabbi Karo is affectionately referred to as the "Mechaber" ("the Author"), i.e. the rabbinic author par excellence.
