Ohr Somayach, Jerusalem
Ohr Somayach (also Or Samayach or Ohr Somayach International) was founded in 1970. It is a yeshiva based in Jerusalem, Israel, catering mostly to young Jewish men, usually of college age, who are already interested in learning about Judaism. It is known as a "baal teshuva" yeshiva since it caters to Jews with little or no background in Judaism, but with an interest in studying the classic texts such as the Talmud and responsa. Students are recruited either locally or from other countries where the yeshiva has established branches, such as in the United States, Canada, South Africa, United Kingdom, Australia, Ukraine and Russia.
In 1970, Rabbis Noah Weinberg, Mendel Weinbach, Nota Schiller, and Yaakov Rosenberg, founded Shema Yisrael Yeshiva to attract young Jewish men with little or no background in Jewish studies. Weinberg left the yeshiva over a difference in philosophy and founded Aish HaTorah in 1974.
