Radoshitz (Hasidic dynasty)
Radoshitz, also spelled Radishitz, is the name of a Hasidic dynasty founded by Rebbe Yisochor Ber Baron (1765–1843) of Radoshitz, also known as the Saba Kadisha. He primarily studied under the Seer of Lublin and the Holy Jew (the Yid HaKadosh). He was particularly dedicated to the mitzvah of Kiddush HaChodesh, the sanctification of the month.
Radoshitz is the Yiddish name of Radoszyce, Świętokrzyskie Voivodeship, a town in present-day Poland.
