The 13th of Iyar marks the day of the passing of Reb Yisrael Aryeh Leib Schneerson in 1952. He was the youngest of Rabbi Levi Yitzchak and Chana Schneerson’s three sons.
Born in Nikolayev in 1909, seven years after the Rebbe, he quickly became renowned as a scholar of exceptional genius. At a young age, Yisrael Aryeh Leib was already teaching Tanya, the mystical foundational work of Chabad Chassidism, to an audience of eager adults.
He eventually immigrated to Israel, and in his later years, he moved to Liverpool, England, to study in the local university. It was there that he passed away in 1952. He is interred in Safed, Israel.
Watch he Rebbe ask Professor Paul Rosenbloom for help in publishing his brother’s work in mathematics, as well as draw a lesson from his brother’s name.
