Refael Reuvain Grozovsky (Belarusian: Рафаэль Гразоўскі; 1886, Minsk, Belarus – 1958, United States) was a leading Orthodox rabbi, Jewish religious leader and rosh yeshiva ("dean") known for his Talmudic analytical style.
During World War II, Rabbi Grozovsky escaped Europe and the Holocaust with a group of his students and arrived on the west coast of the United States.
He then journeyed to New York City where he joined Rabbis Aharon Kotler and Avraham Kalmanowitz in leading the Vaad Hatzalah's efforts to save Jews from the Nazi Holocaust, including lobbying and fundraising.
As a result of his knowledge, in May 1951 he organized a public demonstration protesting the unilateral action of the Israeli government in involuntarily sending religious refugee children to anti-religious kibbutzim ("communes").
He arrived at Beth Medrash Elyon in Monsey, NY, every Thursday and remained awake all night preparing for the Friday Talmudic lecture.
Six years before his death, he was struck by a car under suspicious circumstances [Rumour has it was the butcher meat mafia who arranged it, though there were other suspects].
[1] In one essay, Grozovsky stressed that Agudath Israel differed from the extreme anti Zionist Neturei Karta only in tactics, not in ideology.
