Today, the 11th of Cheshvan, marks 100 years since the passing of Rabbi Schneur Zalman Aharon, son of the Rebbe Maharash. Razoh, as he was known, was born on the 19th of Tammuz, 1847, 5607 to his father, the Rebbe Maharash and his mother Rebbetzin Rivka. He was named after the Alter Rebbe and his maternal grandfather, Rabbi Aharon Aleksandrov of Shklov.

The Rebbe Tzemach gave each baby boy in the family an acronym, and so he was known as "Razoh".

When he was but a tot of three, the Rebbe Tzemach Tzedek suggested him as a match, to his son Rabbi Yisroel Noach. Rabbi Yisroel Noach hesitated, saying that maybe he won't grow up to be a Talmid Chochom. The Tzemach Tzedek replied:" A Talmid Chochom like you he will surely be, and possibly he will learn better than you."

Razoh was blessed with many talents, and refined middos. His father, the Rebbe Maharash said of him: He has a 'strong' head, and is able to think two thoughts simultaneously."

The Rebbe Rayatz spoke about his uncle, the Razoh, at a farbrengen. "My uncle possessed refined attributes from birth. He had a strong heart. Even as he suffered greatly- and he did indeed endure much suffering in his lifetime- he was always smiling. He never shed a tear over his own pain, but when he heard about another's suffering, his smile faded and tears glistened in his eyes, and he did all in his power to help the one in pain."

After his father's histalkus, the Razoh refused to become Rebbe, went into business, and assisted Kllal Yisroel in many ways.

The Razoh passed away on the 11th of Cheshvan, at the age of 51. Before his passing he torched all his manuscripts, put the ashes into a small packet, and asked that it be buried alongside him. He was laid to rest in the city of Vitebsk.
