He moved to Belgrade, Yugoslavia (present-day Serbia), after the war, where he pursued music and Jewish cultural activities. He served as the long-time leader of the Federation of Jewish Communities's cultural department.[1] He also participated in Jewish summer camps, which attracted campers from throughout the former Yugoslavia.[1]
