1863 - 1940 (5 Av 5700) HAYYIM OZER GRODZENSKI (Poland)
Appointed Rabbi in Vilna at the age of twenty-four. He spent much of his time trying to alleviate the plight of the poor, the yeshivot, and the constant refugees. An early leader of the Agudas Yisroel Movement, he was embroiled in many controversies over liberalism and the Zionist movement, and always maintained a strictly conservative view. His Responsa Achiezer was published in three volumes and established him as a leading Torah authority.
