Zamir was born in Warsaw in Poland on April 15, 1931, and immigrated with his parents to Palestine at the age of three.

Zamir demanded from Moshe Arens, then Minister of Defense, to appoint a committee to investigate the accusations.

Prime Minister Shimon Peres refused and removed Zamir from office, replacing him with Joseph Harish.

In December 1991, Zamir quit his job claiming that he is not trusted and has not authority, as he had no power to place sanctions over journalists who broke the ethical code.

In 1991 Zamir was appointed as the first Dean of the newly established Faculty of Law in the University of Haifa, and served there until 1994.
