Menachem Mendel Schneersohn (Last Lubavitcher Rebbe)

Menachem Mendel Schneerson, known as "the Rebbe," was the last rebbe of Chabad-Lubavitch Chasidut and a pioneer of Jewish outreach who led Chabad to become a major influence on worldwide Judaism. He succeeded his father-in-law as rebbe in 1951 and expanded the shelichut (representative) system his predecessor had established, sending yeshiva students to far-flung communities to reconnect Jews to their heritage. His international impact also included helping Iranian Jews during the 1979 revolution and providing for religious needs of Soviet Jews. Most of his vast published scholarship was culled by others from his talks, personal notes, and correspondence.
