Israel Salanter
Born in Zhagare, Lithuania, into a rabbinical family, Israel ben Ze’ev Volf Lipkin (widely known as Israel Salanter) was the founder of the Musar ethical movement, which stressed dedication to moral virtues along with strict adherence to religious commandments. In the early 1840s, Salanter established a Musar house in the Vilna area, where he taught moral and behavioral concepts to a generally middle-class society. In 1848, he declined an offer to teach at a government-created yeshiva in Vilna and moved to Kovno; then, facing opposition for allegedly separating the community into groups, he moved to Prussia, where he opposed the rise of modern Orthodoxy.
