Yahrtzeit of Rabbi Meir Shapiro of Lublin (1887-1933), the founder and driving force behind the Daf Yomi, a program of daily Talmud study. Today, tens of thousands of Jews study the "daily daf," and every seven-and-a-half years a "siyum" (completion) of the Talmud is held with large celebrations in Madison Square Garden and other locations worldwide. Rabbi Shapiro represented the Jews in the Polish Senate, and he built the grand Chachmei Lublin Yeshiva in Poland, a building which remains standing till today. Sadly, Rabbi Shapiro passed away at the young age of 46. His remains were later re-interred to a cemetery in Jerusalem.
