Tomb of Menachem Mendel Schneerson

Menachem Mendel Schneerson, known to adherents of the Chabad-Lubavitch movement as the Lubavitcher Rebbe or simply the Rebbe, was an Orthodox rabbi and the most recent Rebbe of the Lubavitch Hasidic dynasty. He is considered one of the most influential Jewish leaders of the 20th century.

As leader of the Chabad-Lubavitch movement, he took an insular Hasidic group that almost came to an end with the Holocaust and transformed it into one of the most influential movements in religious Jewry, with an international network of over 5,000 educational and social centers. The institutions he established include kindergartens, schools, drug-rehabilitation centers, care-homes for the disabled, and synagogues.
