His father, Sinaj Zygmunt, the owner of a prominent paper wholesale business, was communally and philanthropically active as a member of the city council and one of the leaders of the Jewish community.
He began to travel further afield with his camera, producing photographs in Poland, Japan, the United States, Egypt and in a considerable number of other countries.
He also took portrait photographs of central figures in the Zionist movement of the time, including Hayim Nahman Bialik, Uri Zvi Greenberg, Ze'ev Jabotinsky, Abba Ahimeir, Haim Arlosoroff, Nahum Sokolow, Yitzhak Ben-Zvi and others.
Eleven years after his death, a tattered leather suitcase was discovered by chance at his home, in which the fruit of his art was hidden – more than 15,000 negatives found rolled up in rusty tin boxes.
Researchers and professionals judged the worth and value of the collection following a lengthy process of scanning and identifying of photographs by place, person, and date.
