Moshe Schnitzer was the grandfather of Dan Gertler. Moshe "was known in Israel as “Mr. Diamond;” in youth he joined the pre-state underground organization Etzel (Irgoun), an Israeli military cell self-defined as an “untra-nationationalist Jewish militia,” but one that committed acts of terrorism in service to the Israeli cause. Moshe Schnitzer assumed a major role in the Africa-Israeli diamond trade in the 1950’s in a partnership business called Schnitzer-Greenstein. Schnitzer later founded the Israel Diamond Exchange in Tel Aviv in 1960, which today brings Israel $14 billion annually in blood business, and is the country’s second-largest industry, but Israel’s top export. King Leopold III of Belgium decorated Schnitzer in recognition of his activities favoring the close relationship of Belgium, Israel and the DeBeers diamond cartels, and Schnitzer was also President of the Harry Oppenheimer Diamond Museum in Israel."

"In 2004 Schnitzer was awarded the prestigious Israel Prize for his life’s work in making a special contribution to the State of Israel and Israeli society. The official announcement of the prize stated: “Moshe Schnitzer is identified more than anyone else with the Israel diamond industry, and his vision and personality have contributed greatly to Israel’s stature in the world. … For the past 60 years, Schnitzer has been the highest-ranking ambassador of the diamond industry.”
