Rabbi Meir Shlomo Ha'Levi Yanovsky (; 1850 â September 14, 1933) was a rabbi of Nikolayev, a composer of Chabad music, and the grandfather of Rabbi Menachem Mendel Schneerson.
Yanovsky was born to Rabbi Yisrael Leib of the Romanivka Chabad and the daughter of Rabbi . He was raised and educated by his grandfather in Nikolaev, who designated him as his successor in the rabbinate. By the time he grew up, he married Rachel Poshnitz, daughter of Rabbi Yitzhak Poshnitz of Dobrynka. After his marriage, he spent time in the court of Rabbi Shmuel Schneersohn in Lyubavichi. After the death of Rabbi Shmuel, he became a Chassid to Shmuel's son, Sholom Dovber Schneersohn. Rachel was murdered in the Holocaust.
After completing his studies in Lyubavichy, Yanovsky returned to Nikolaev to live with Lavut before his death on March 10, 1890. His grandfather gave a letter before his passing to the leaders of the Jewish community in the city requesting that Yanovsky be appointed as the city's rabbi as a replacement, as was done in 1890.
At one point, Yanovsky fell ill during a local Typhus outbreak. A fellow Nikolaev rabbi, Asher Grossman, came each day to read to him from the Tanya, which Yanvovsky had attributed as a significant part of his recovery from the illness.
Yanovsky and his wife had a total of 3 children:
