David Horowitz (1903 – 2002) was the founder of the United Israel World Union and one of eight children of Cantor Aaron and Bertha Horowitz whose family immigrated to the United States in 1914. He first went to the land of present-day Israel in 1924 as an ardent Zionist. He married and moved to Poland in 1927 where he lived with his wife's parents during her pregnancy and played a part in trying to rescue Jews from the Nazi death machine as it rolled across Europe. He moved to the U.S. in 1943 where he became an accredited correspondent to the United Nations and founded the United Israel World Union. The purpose of his organization was to preach a universal Hebraic faith for all humankind based on the Decalogue and the other universal commandments of the Torah. The hallmark of the organization was Isaiah's prescription that:
My house will become a house of prayer for all peoples ...This is the same verse that Herbert W. Armstrong used for his reason to build the Ambassador Auditorium in Pasadena, California, and Armstrong once announced a plan to assist in the building of a Jewish/Christian/Islamic center at Mount Sinai with the blessings of both Egyptian and Israeli leaders.
Horowitz was also the long-time editor of the United Nations Correspondents Association's quarterly newsletter and was the author of the 1986 biography "Pastor Charles Taze Russell: An Early American Christian Zionist." The book detailed the pro-Zionism writings and sermons of the founder of the Watchtower Bible Society, better known as the Jehovah's Witness movement.
