Rav Chaim Shmuelevitz - (1902-1979), Poland, Shanghai, Yerushalayim; Grandson of the Alter of Novhardok. Member of the faculty of the Mirrer Yeshiva for more than 40 years, in Poland, Shanghai and Jerusalem, serving as Rosh yeshiva during its sojourn in Shanghai from 1941-47, and in Jerusalem from 1965-79. Well known for his ability to become totally engrossed in his Torah study for hours at a time. His ethical discourses, many of which have been published in English, are considered classics. During the Six-Day War, when the yeshiva was within range of Jordanian artillery fire, Rav Shmuelevitz sent some of his father's handwritten manuscripts to America with his uncle, Avraham Yoffen, with specific instructions that he carry them by hand and not put them in his luggage, because, "Dos iz meyn gantze leben (This is my whole life)."
