Don't mix with Rabbi Yehudah Tzvi of Stretin who Died: Stretin, Poland, 1844.

Rabbi Yehudah Tzvi Eichenstein was born in 5618/1858. His father was Harav Yissachar Dov Berish, son of Harav Yitzchak Eizik of Ziditchov. He was named after Harav Yehudah Tzvi of Rozdol, who was Rebbe before Reb Yitzchak Eizik.

When Reb Yitzchak Eizik was niftar in 5633/1873, his son Rav Yissachar Berish was appointed Rav and Rebbe in Dolina.

Reb Yehudah Tzvi became the son-in-law of Harav Moshe Ungar of Dombrova. Following his wedding, Reb Yehudah Tzvi settled in Sanz, near the court of his wife’s maternal grandfather.

Then, following the petirah of his father on Erev Rosh Chodesh Adar 5646/1886, Reb Yehudah Tzvi, the only son, was appointed to succeed him as Rebbe in Dolina. His court flourished there, attracting many Chassidim.

Reb Yehudah Tzvi was close with many Rebbes of his time, most notably with Harav Yehoshua of Belz.

The divrei Torah of Reb Yehudah Tzvi were not printed; only some of the introductions that he wrote to the sefarim of both his father and his uncle remained.

Reb Yehudah Tzvi was niftar on 12 Iyar 5669/1909, at the age of 51.

Since he left no son, his court passed to his two sons-in-law, Harav Yehoshua Halberstam and Harav Pinchas, the son of Harav Moshe Rokeach of Karov. Both resided in Dolina.

May the merit of the Tzadik Rabbi Yehudah Tzvi Eichenstein  protect us all. Amen
