He died in 1933, but his imprint on Jewish posterity intensifies steadily. Halachist, Talmudist, ethicist, educator, leader, author, innovator, diplomat, saint -- the Chafetz Chaim did so many things so well that the range of his activity and achievement is mind-boggling.

For decades, the monumental work of Rabbi Moses M. Yoshor has been the definitive biography of the saint and sage of Radin. Rabbi Yoshor was not only a student of the Chafetz Chaim, but was also close to the family. He collected biographical material on his great mentor and began to commit it to writing shortly after the Chafetz Chaim’s passing.

Rabbi Chaim Ozer Grodzensky, the world-renowned sage of Vilna who was the Chafetz Chaim’s most intimate contemporary, gave warm praise to Rabbi Yoshor’s book. He wrote that the author had succeeded in capturing the essence of the great gaon and tzaddik, and in presenting the reader with an accurate portrait of a man who inspired love and reverence for nearly a century.
