Weissenstein documented the Jewish everyday and cultural life in Tel Aviv, including numerous prominent personalities - artists and politicians, such as Marc Chagall, Max Brod, Eleanor Roosevelt, Isaac Stern and the painter Nahum Gutman. He photographed for the Israel Philharmonic Orchestra since the first concert conducted by Arturo Toscanini. Weissenstein's most well-known photograph is that of the Declaration of Independence of the State of Israel on May 14, 1948, by David Ben Gurion, where he was the only accredited photographer.[2]
