He was the youngest son and successor[2] of Shlomo Rabinowicz, who founded the dynasty in the Polish town of Radomsko (Radomsk) in 1843.
[1] Rabinowicz headed a committee established by his father which raised money to ransom new recruits from the forced conscription of young Jewish men to the army, which was rife with antisemitism.
[1][5][6] Rabinowicz, who suffered from diabetes,[2] died in Radomsk on September 5, 1892 (13 Elul 5652) and was buried there next to his father.
His grandson, Shlomo Chanoch Rabinowicz, also had diabetes, but as insulin was invented in 1921, did not die of it; he was murdered by the Nazis in the Warsaw Ghetto at the age of 60.
[1] Rabinowicz's Torah teachings were compiled under the title Chesed L'Avraham, published in Piotrkow in 1893.
