Mordecai Menahem Kaplan (June 11, 1881 – November 8, 1983) was an American Conservative rabbi, writer, Jewish educator, professor, theologian, philosopher, activist, and religious leader who founded the Reconstructionist movement of Judaism along with his son-in-law Ira Eisenstein. He has been described as a "towering figure" in the recent history of Judaism for his influential work in adapting it to modern society, contending that Judaism should be a unifying and creative force by stressing the cultural and historical character of the religion as well as theological doctrine.
