R. Rozin's imposing and majestic appearance made a deep impression on all who saw him. Though one of the greatest scholars of any age, he was essentially a humble man. He was courteous, striving to see things from the other man's point of view. He bore the physical pain of his closing years stoically, though grudging the time it took him from learning, and continued to answer all who consulted him, whether in writing or in person. During his lifetime R. Rozin published a commentary on Maimonides' Mishneh Torah in five volumes (1903–08) and two volumes of responsa. Four further volumes of responsa were published in 1935–38. During World War II, one of his students, R. I. A. Sufran-Fuchs, photographed all the manuscripts he could collect and sent the films to a relative in the U.S. They have subsequently been in the process of publication. All his works appear under the title Zafenat Pa'ne'ah. A number of volumes of the novellae and the commentary on the Pentateuch have appeared (5 vols., 1960–65). R. Rozin died in Vienna and was buried in Dvinsk.
