Rav Chaim Ozer Grodzinski

Rav Chaim Ozer Grodzinski (August 24, 1863 - August 9, 1940) was a leading posek and gadol in Europe. Rav Chaim Ozer was gifted with an infallible memory - never experiencing "forgetting," as he himself remarked, until his old age. At fifteen, he went to the world-renowned Yeshiva of Volozhin. In spite of his tender age, he was immediately accepted into Rav Chaim Soloveitchik's select group. By the age of twenty, when he passed through Vilna, he was already well-known as an outstanding posek.

Rav Chaim Ozer Grodzinski's brilliance as well as the scope of his leadership are reflected both in the halachic queries that were sent to him from all parts of the world and in the responsa he sent in return. He would write each responsum personally, not entrusting this to a secretary. His mind was so disciplined, that he would simultaneously write a responsum in halachah, give orders to two secretaries, and speak on the telephone.
