The city of Vilna was known as "the Jerusalem of Lithuania"and it was the scholarship of Rabbi Eliyahu of Vilna that made it so. Known for his superhuman schedule of Torah learning in which he very seldom slept, the Gaon was not only a giant in Torah and Talmud but deduced from the Holy Writings knowledge of science, mathematics, and music. Called "the father of the yeshiva movement,"higher Jewish education bears the stamp of his ideas.
