Avigdor Neumann was born in Velká Sevljuš, Czechoslovakia (Yiddish: Selish, preset-day Vynohradiv, Ukraine) in 1931 to a Hasidic family. In 1939, the city was annexed by Hungary and was renamed Nagyszőlős. In 1944, the city's Jews were imprisoned in a ghetto and deported to Auschwitz-Birkenau. Afterwards Avigdor was transferred to the Althammer camp and later sent on a death march to Mauthausen. After liberation, Avigdor and his sister immigrated to Israel. Avigdor married Rivka and they had children, grandchildren and great-grandchildren.
