Yitzchok Yaakov Weiss
Rabbi Yitzchok Yaakov Weiss, commonly known as the Minchas Yitzchak after the responsa he authored, was the rabbi of the Edah HaChareidis in Jerusalem at the time of his death, as well as a posek, and Talmudic scholar. His rulings on Jewish law are frequently cited and relied upon by rabbinic courts and scholars.
Early life
Weiss was born in the town of Dolyna in Galicia and Lodomeria|Galicia], Austria-Hungary, the son of a chassidic rabbi, Yosef Yehuda Weiss, who was later head of the Hungarian Jewish community in Munkacs. He had frequent encounters with the Ziditchover Rebbe, Yehuda Zvi Eichenstein, until the age of seven when the latter died. However, with the onset of World War I in 1914, he moved with his parents to Munkacs in Hungary, where his father had lived before marrying. In 1918, the region was under the rule of independent Czechoslovakia.Weiss studied under his father and received semicha from the Munkatcher Rebbe, Chaim Elazar Shapiro. Soon after, he also received semicha from Rabbi Meir Arik of Tarna. He also became close to Rabbi Shimon Greenfield. At the age of 20 he became a Rosh yeshiva in the town.
Career before WWII
Weiss was the Av Beth Din in Grosswardein, Romania, before World War II. When Grosswardein was ceded to Hungary as a result of the Vienna Award he fled to Romania in 1944, where his wife died of an illness. When the Nazis occupied the area and sent Jews to be murdered he and his family escaped them by hiding in bunkers and attics.Post-World War II
Around 1949 he emigrated to Manchester, England, where he was soon appointed Dayan and Av Beth Din. His appointment was hailed as an important event in the religious life of English Jewry. The then-Chief Rabbi Sir Israel Brodie and his successor Rabbi Immanuel Jakobovits, were in attendance at Rabbi Weiss's induction in the Manchester Great Synagogue.Weiss remained in Manchester until 1970. After his retirement as head of the Manchester Beth Din he joined the Edah HaChareidis in Jerusalem and became its head in 1979 when Yoel Teitelbaum died.

Weiss wrote a ten-volume set of responsa, Minchas Yitzchak, discussing many contemporary technological, social, and economic issues. In a section entitled Pirsumei Nissa Weiss recorded the extreme ordeals that he experienced in the Second World War.Weiss also wrote Siach Yitzchak on the Talmudic tractate Chagigah.
