When his brother realized that there was no future for Zuckerman in the rag trade, he decided to set him up in an enterprise of his own and put a down payment on a candy store in his name.

As his relationship with the candy store was drawing to a close, Zuckerman was elected a delegate to the founding convention of Poale Zion of America that took place on May 1, 1905.

It was not until 1932 that the Zuckermans finally made aliyah, and Avivah who had been studying at Hunter College in New York enrolled at the Hebrew University, becoming one of its first students of bacteriology.

After the Zuckermans moved to Jerusalem, where their daughter Nomi attended the Gymnasia Rehavia, their house became a meeting place for all the leading figures of the Zionist Movement.

In August 1939, on the eve of Hitler's invasion of Poland, both Baruch and Nina Zuckerman were delegates to the 21st Zionist Congress in Geneva.

Nomi spent the major part of the war years studying - first at Columbia University, then at the Tyler School of Fine Arts before returning to Jerusalem with her parents at the end of 1945.

The idea of establishing a memorial in Palestine for Jewish victims of the Nazi Holocaust was conceived during World War II, as a response to reports of the mass murder of Jews in Nazi-occupied countries.

Yad Vashem was first proposed in September 1942, at a board meeting of the Jewish National Fund, by Mordecai Shenhavi, a member of Kibbutz Mishmar Ha'emek.

Their daughter Avivah Zuckerman was a gifted, prize-winning poet, Haganah activist and later a world-renowned Hebrew University professor of parasitology.
