(Cleveland Jewish News)(This article has a nice summary of the history of Chabad Worldwide and Cleveland. Sorry this was published after the yahrtzeit.)
Rabbi Menachem Mendel Schneerson, known as the Lubavitcher Rebbe, is widely considered the most influential rabbi in modern history.
As his 20th yahrzeit approaches, the Chabad-Lubavitch movement remains vibrant, thanks to Schneerson’s vision, said Rabbi Leibel Alevsky, Chabad regional director and executive director of Chabad of Cleveland, based in Beachwood.
