R. Botschko was born in 1892 (and died in 1956). A student of several yeshivas in Lithuania, R. Botschko emigrated to Switzerland during the First World War. In 1927, he founded in Montreux the Etz Chaim Yeshiva , the first Yeshivah (Talmudic school) of Switzerland, the only one of the few established in Western Europe that could be sustained at the time of National Socialism . He was a member of the Central Council of Agudat Israel (Orthodox Jewish organization), and he had a great influence on the development of Orthodox communities in Switzerland and Western Europe. In 1985, his son and successor, R. Moshe Botschko, transferred the Yeshivah in Jerusalem.
