Born circa 1928 in Brooklyn, NY, Rabbi Theodore Steinberg was a Conservative rabbi ordained at The Rabbinical School of the Jewish Theological Seminary. Upon retiring from serving as a pulpit rabbi, he moved to Jerusalem, Israel. In 1980, Rabbi Steinberg completed his dissertation "Max Kadushin, Scholar of Rabbinic Judaism: A Study of His Life, Work, and Theory of Valuational Thought" at New York University on the life of the rabbinics scholar Max Kadushin; Steinberg's work was the first scholarly volume on Kadushin's life and studies.
In later life, Steinberg served (starting in 1996) as Associate Editor of the Jewish Bible Quarterly and volunteered regularly at the Jerusalem Botanical Gardens.
Various responsa of the Committee on Jewish Law and Standards of the Rabbinical Assembly credit him with having asked questions relevant to the subject matter dealt with in the published responsa (including issues of non-Halakhic conversions to Judaism, and the triennial cycle of Torah reading).
Rabbi Steinberg died in 2009.
