Hager was the fifth rebbe, or leader, of the Vizhnitz Hasidic dynasty, which is named after a town in modern-day Ukraine where the sect began.
Born in 1922, Hager was believed to be the world’s oldest Hasidic leader. His wife, Simi Mirel Hager, died in 2005 at the age of 76. She was also sister of Grand Rebbe David Twersky of New Square.
The Rockland Fire Department issued a warning via Twitter that “tens of thousands” were expected at services for Hager, potentially creating major traffic delays. The Ramapo Police Department is urging drivers to avoid the area.
