Menashe Klein

Menashe Klein (1924–2011) (Hebrew: ר' מנשה קליין), also known as the Ungvarer Rav (Yiddish: אונגווארער רב), was a Hasidic Rebbe and posek (arbiter of Jewish law). He authored 18 volumes of responsa, spanning over 50 years, entitled Mishneh Halachos. Additionally, he authored some 25 other seforim, including a commentary on Rabbi Simeon Kayyara's BeHag. Toward the end of his life, he relocated from Brooklyn, New York to Jerusalem.

Menashe Klein was born in 1924 in the town of Orlova (now known as Irlyava) near the city of Ungvar, Czechoslovakia (currently located in Ukraine). He studied in the yeshiva of the Rav of Ungvar, Rabbi Yosef Elimelech Kahane.

During World War II, he was incarcerated in Auschwitz-Birkenau, Auschwitz-Buna, and finally in Buchenwald. At Buchenwald, he was sent out to "Stein," a Nazi satellite camp at Eschershausen, but was listed in camp records as returned to Buchenwald, where he was liberated and where he completed a postwar military interview.

On June 2, 1945, he was evacuated by train with 427 other former Buchenwald inmates ages 7 to 17 – among them Yisrael Meir Lau, Naphtali Lau-Lavie, and Elie Wiesel – to France, where they boarded at a sanitarium in Écouis. He was transferred to Ambloy together with about 100 other boys who desired kosher facilities and a higher level of religious observance. This group was under the supervision of social worker Judith Hemmendinger, who attempted to re-acclimate the boys to normal living. The group was transferred to Taverny after Yom Kippur 1945. Klein immigrated to the United States in 1947.

After World War II, he served as Rav in the "Chevrah Liyadi" shul, (which was located in the Williamsburg section of Brooklyn) and Principal of Yeshivas Shearis Hapleitah, under the direction of Rabbi Yekusiel Yehudah Halberstam, Klausenberger Rebbe. In 1964, he founded Yeshiva Beis Shearim in Borough Park, Brooklyn, where he served as rosh yeshiva.

In 1983, he established Kiryat Ungvar in the Ramot section of Jerusalem in memory of his hometown. Today, it is a thriving neighborhood with hundreds of inhabitants.

The Ungvarer Rov was active until old age. He had thousands of disciples.

He died on the last day of Elul (September 28) 2011, and was buried in Tzfas, near the grave of the Arizal, the Alshich Hakadosh and Beis Yosef.
