Boruch Hager

Boruch Hager was born in 1845 and was named after Rabbi Boruch of Medzhybizh at the behest of his grandfather, Yisroel Friedman of Ruzhyn. In 1885, aged 40, he inherited the mantle of leadership from his father, Menachem Mendel Hager, and became rebbe to thousands of chasidim. He led them for only 8 years until his death in 1892. His Torah thoughts were collected in Imrei Boruch by his son-in-law. Eight of his sons became rebbes in different locals: His eldest, Reb Yisroel, succeeded him in Vyzhnytsia; Reb Chaim became rebbe in Ottynia; Reb Moshe in Suceava; Reb Shmuel Avrohom Abba in Horodenka; Reb Yaakov Yitzchok Dovid in Storozhynets; Reb Pinchos in Borsha; Reb Feivish in Zelishtshik; Reb Yechiel Michel succeeded his brother in Horodenka. Another son, Reb Sholom, died in his youth. His sons-in-law were Reb Shmuel Dov Chodorov of Petriva; Reb Mordechai Chodorov of Kolomea, who published Imrey Boruch; Reb Sholom Yosef Friedman of Sadigur-Chernovitz.
