Rabbi Moshe Kotlarsky, who helped establish scores of outposts around the world for the Chabad-Lubavitch Hasidic movement and served as a global ambassador to aid its far-flung emissaries in accomplishing their mission to revitalize Jewish life, died on June 4 at his home in Crown Heights, Brooklyn. He was 75.

Rabbi Kotlarsky traveled tens of thousands of miles to respond to requests for an institutional presence in sparse Jewish communities in Africa, Asia, the Caribbean, and the former Soviet Union. He was particularly effective in setting up many of the 346 sites now servings 818 college campuses in 23 countries, exposing nonobservant Jewish students to the faith’s traditions and thought.
