In the Bronx, Twersky was an active communal leader, spearheading the drive to preserve the local mikvah and serving as a chaplain with the New York City Police Department.
The heir to the Chernobyl rabbinic dynasty, Twersky was also an ardent supporter of Zionism who was active in annual appeals for the state of Israel.
“He was a rabbi cut from the old-style European cloth,” said his eldest son, Mordechai. “Despite what he saw during the Holocaust, he was a man of unshakable faith.”
Twersky is also survived by a daughter and another son, three sisters and six grandchildren — as well as by his wife of more than 40 years.
