Rav Dov Ber was the son of Rav Moshe Fromer and Hendel of Kishanov and a talmid muvhok of Rav Shlomo of Kishanov.
He also studied Chassidus under the Chozeh, testifying that “the light of Torah lishmah shines forth from him.”
In Oshpitzin there lived a wealthy gvir named Rav Nota Tyberg, who hired Rav Dov Beirish as a personal melamed for his bright and gifted son, Rav Yudele Tyberg (great-grandfather of Rav Moshe Danziger of Alexander, the brother of the Yismach Yisrael). (MeOran Shel Yisrael Likkutim 356)
Eventually, Rav Shlomo of Kishanov discovered him and sent his talmidim to draw near the light hidden in Oshpitzin. It was those talmidim the Kishanover sent who brought him to his Rebbe and mentor in Chassidus.
Rav Dov Ber authored the sefer Divrei Tzaddikim.
