Yahrtzeit of Rabbi David HaLevi Segal (1586-1667), better known as the Taz, an acronym of his famous work of Jewish law, Turei Zahav. Now, four centuries later, "Taz" is printed in every standard edition of the Code of Jewish Law (Shulchan Aruch). The Taz was the son-in-law of the famous rabbi, the Bach. He narrowly escaped when the Cossacks attacked his Polish town. Legend says that 200 years after his death, his grave was accidentally opened and his body was found intact.
