Rabbi Yehuda Meir Shapiro was born on the 7th day of Adar (in Jewish tradition, also the birth date of Moses[1]) in the city of Shatz, Bucovina, then in the Austrian-Hungarian Empire, now in Romania, in 1887.

He spent ten years in the city, during which time he established a yeshiva called Bnei Torah.

The yeshiva held a Talmud Torah, a place to train rabbis, and a kitchen to feed orphaned children.

Shapiro introduced the revolutionary idea of Daf Yomi (Hebrew: דף יומי, "page [of the] day" or "daily folio"), a daily regimen undertaken to study the Babylonian Talmud one folio (a daf consists of both sides of the page) each day.

Whilst serving in Galina, Rabbi Shapiro began his involvement with Agudat Israel.

He played a role in the conference in the city of Lvov, which had the purpose of launching the Aguda in Galicia, some two years after its founding in Katovitz in 5672 (c. 1911).

Rabbi Shapiro, together with Aron Levine and Zalman Sorotzkin, chaired the committee which as a part of the Polish Ministry for Religious Affairs, held responsibility for delegating Rabbinical positions throughout Poland.

Countless newspapers across the entire political spectrum, from Orthodox to Yiddishist to socialist, featured front-page biographies of Rabbi Shapiro.

Rabbi Yitzchok Meir Levin delivered a eulogy, as did those students of his who had survived the Holocaust.
