Rav Dovid Hirsch Mayer, Rosh Yeshiva, Bais Binyomin, Stamford, Connecticut, was the son of Rav Yitzchok Zev Mayer (Nitra, Czechoslovakia), mechaber of Maharsha Ha’Oruch, a close friend of Rav Michoel Ber Weissmandl. His mother, Lea, was the main character in the famous story of the woman who demanded a knife for her newborn son as she was being taken away to a concentration camp; she then circumcised her eight-day-old child. The child was Rav Dovid Hirsch’s older brother, Menashe. The family survived and moved to America. Rav Dovid Hirsch learned at the Nitra Yeshiva in Mount Kisco, NY, then in Lakewood. He was close to Rav Shneur Kotler and Rav Nosson Wachtfogel and was instrumental in the founding of the Los Angeles Kollel. He founded Bais Binyomin in 1977.
