Rabinowitz was born in Russia and at a young age immigrated with his family to the United States. His father, Rabbi Moshe Zvi Rabinowitz, was a rabbinical leader in Brooklyn, New York. In August 1950 Rabinowitz immigrated to Israel, becoming the first member of the law faculty in the Hebrew University of Jerusalem to teach Hebrew law. His publications, both in English and Hebrew, researched the Torah and Talmud. Rabinowitz died in Jerusalem.
