In 1953, Weinberg traveled to Israel to consult with the Chazon Ish regarding the response needed to counter the threat of assimilation in the Jewish world. However, the Chazon Ish died while Weinberg was en route to Israel.
As part of his job working as a salesman for his brother's company, Weinberg traveled to many small cities in the United States. During these trips, he encountered Jews of all kinds who were distant from their heritage.[5]
Aish HaTorah
In 1966, Weinberg decided to enter the field of kiruv (Orthodox Judaism outreach), and he opened the first yeshiva in this style for Jewish men in Jerusalem. The school was short-lived, as were several other attempts, before he co-founded Yeshivas Shma Yisrael (later renamed Ohr Somayach) in 1970 with Nota Schiller, Mendel Weinbach and Yaakov Rosenberg .
After a few years, Weinberg broke away from the partnership over a difference in educational philosophy. He believed that the times called for the call up of "kiruv soldiers"—people who would be given a few years of basic education training, and then sent out to give introductory classes to other young Jews at risk of assimilation and intermarriage. Weinberg established Aish HaTorah with five students in a small apartment in Jerusalem's Old City in 1974.[6][7] In addition to its Jerusalem headquarters, Weinberg helped establish an Aish HaTorah branch in St. Louis in 1979. The organization later grew to 30 branches worldwide.
In 1985, Weinberg launched the Discovery Seminar,[7]: p.21 a multi-day seminar designed to introduce proofs of God's existence to audiences all over the world. The organization claims that the seminar has been presented to over 100,000 people worldwide.[8] That same year, Weinberg launched the Jerusalem Fellowships, which brought college age Jewish people to Israel.[citation needed]
In 2001, Weinberg founded the Hasbara Fellowships program to bring university students to Israel for an intensive two-week Israel activism training course.[citation needed]
In recognition of Aish HaTorah, the Israeli government awarded Weinberg the last two building sites adjacent to the Western Wall. In 1996, he dedicated his newly designed yeshiva as the central location for Aish HaTorah's manpower and leadership training programs.
Weinberg was diagnosed with lung cancer in 2007. He died on February 5, 2009. He was survived by his wife Denah, twelve children and more than 100 grandchildren and great-grandchildren.[10] Denah died on Sunday evening, 12 March 2023.[11]
