Shlomo Chanoch Hakohen Rabinowicz (also spelled Rabinowitz, Rabinowich, Rabinovitch) (1882 – 1 August 1942) was the fourth and last rebbe of the Radomsk hasidic dynasty.

[1] On the eve of World War II, Radomsk was the third largest hasidic dynasty in Poland, after Ger and Alexander.

[1] He was wealthy[4][6] and owned a glass factory and homes in Berlin, Warsaw,[7] and Sosnowiec, where he lived after World War I.

The Rebbe paid for the entire operation, including staff salaries, food, and student lodging, out of his own pocket.

Rabbi David Moshe also served as rosh yeshiva of the entire Keser Torah network, monitoring students' progress, delivering shiurim, and administering the end of the semester tests.

[12] The Rebbe's son-in-law, Rabbi David Moshe Rabinowicz, gave regular shiurim (lectures) in the Warsaw Ghetto, and also composed many chiddushim (novel Torah thoughts) which his students recorded.

[2][13] Rabinowicz and all the members of his family, including his only daughter, son-in-law, and their infant son, were murdered by the Nazis on 1 August 1942.

[14] When the Nazis stormed his house to deport its residents to the Chelmno extermination camp, Rabinowicz refused to leave, saying, "I know you've come to kill me.

His brother, Rabbi Elimelech Aryeh Hakohen Rabinowicz, died in the Mauthausen concentration camp.
