Reb Boruch Sholom, known as the Rabash, was the eldest son of the Tzemach Tzeddek. His great grandfather the Alter Rebbe, expressed a profound love for him. He was extremely modest and refused to become the Rebbe after his father’s passing, unlike his other brothers who all became Rebbes. Both the Tzemach Tzeddek and the Rebbe Maharash would seek his counsel regarding communal matters. He passed away on the 16th of Shevat, תרכ"ט.
The Alter Rebbe taught Reb Boruch Sholom the trop (tune) of Tanach, and Reb Boruch Sholom taught them to the Rebbe Maharash. Even though the Rebbe Maharash had a long breath, singing these notes would strain his heart.
The Rebbe Rashab was once in the home of Reb Yuzik Gurevitz in Warsaw, and there were many chassidim there; the house was packed, and some attendees began pushing. The room quieted, and the Rebbe Rashab began relating, "Once, when the Tzemach Tzeddek was saying Chassidus, his eldest son Reb Boruch Sholom put his foot on the fireplace and wanted to lift his second foot unto it as well. However, because the room was jam packed, he was unable to lift his foot, and was forced to remain in that position for the duration of the entire maamor."
