Yahrtzeit of Rabbi Yisrael Meir Kagan (1838-1933), popularly known as the Chafetz Chaim, the title of his groundbreaking book on the laws of proper speech. The Chafetz Chaim lived in Radin, a small town in Poland that became a center of attention for world Jewry, given the Chafetz Chaim's saintly stature and active involvement in Jewish affairs. The Chafetz Chaim published over 20 books, including Mishnah Berurah, a monumental commentary on the daily living section of the Code of Jewish Law. The six volumes of Mishnah Berurah took 25 years to complete, and it has achieved universal acceptance as the definitive guide to Jewish law for Ashkenazic Jewry. The Chafetz Chaim was equally revered for his sterling character. The Chafetz Chaim passed away in 1933 at age 95, and is buried in Radin.
