Rav Binyomin Aharon Solnik, son of Rav Avrohom, was a talmid of the Rema and of the Maharshal, and one of the leading Talmidei Chachomim in Cracow. After the Rema’s petira, Rav Binyomin Aharon moved to Silesia and later to Podheitz. He corresponded in halachic matters with many Gedolim of his time, notably the Maharam of Lublin; Rav Yosef Steinhart, the Zichron Yosef; and Rav Mordechai Yaffe, the Levush. His sefer Mas’as Binyomin includes 112 teshuvos.
Rav Binyomin Aharon’s sons were all Gedolim. His son Rav Yaakov Yukel was the mechaber of Nachalas Yaakov on Rashi’s commentary on the Torah. Rav Avrohom was Rav of Tarnopol and later Rav in Brisk. His son-in-law was Rav Menachem Mann, Rav in Vienna and later Chief Rav of Austria. Rav Binyomin Aharon was niftar on the twenty-third of Menachem Av 5370/1610. Zecher tzaddik livrachah.
