RosenbaumRabbi Isamar Rosenbaum
1886–1973

Rabbi Isamar Rosenbaum was a rebbe of the chasidic dynasties of Nadvorna and Kretshnif. He was the son of Rabbi Meyer Rosenbaum (1852 – 1908) of Kretshniff, who in turn was a son of Rabbi Mordechai of Nadvorna (1824–1894).

Isamar Rosenbaum became a rebbe at the age of fifteen and, at his father’s behest, moved to Czernowitz where he served as a chasidic rebbe. In the Nadvorna dynasty, all children of the rebbes open their own chasidic courts, even during their fathers’ lifetime. His wife, Rebbitzen Malka, was the daughter of Rebbe Usher Yeshaya Rubin of Kolbuszowa, Galicia.

His family was the only chasidic family of grand rabbis known to have all survived the Nazi camps with the whole family intact.

His wife died in 1969 and was buried in Tveria. In 1970, three years before his death, he moved from the Washington Heights neighborhood of Manhattan to Yad Eliyahu in Tel Aviv, Israel.

At the time of his death, he was one of the longest living chassidic rebbes in history; he was known as the Admor Hazaken miNadvorna, or “Elder Rebbe of Nadvorna”.

He was nifter at the age of 86 in 1973 and was buried on the Mount of Olives.

All his sons and sons-in-law, were chasidic rebbes, with the sole exception of his son Rabbi Meyer Rosenbaum, who was the Chief Rabbi of Cuba and Mexico, and a prolific author of scholarly works, including Torah LeOhr Hatekufah.
