Mordecai Aaron Guenzburg, together with the Hebrew writer Solomon Salkind, founded the first modern Jewish school in Lithuania. Guenzburg (1795-1846) attacked the Heder system of education. Although considered a Maskil (part of the "enlightenment movement"), he was a traditionalist who believed in the Torah. Guenzburg fought against both what he perceived as Orthodox extremism as well as the German Haskalah Movement. He served as the schools headmaster until his death.
