Aaron ben Benjamin Wolf (about 1670 – July 25, 1721) was a Rabbi at Berlin and then at Frankfort-on-the-Oder, where he lived until his death.
His father, Isaac Benjamin Wolf ben Eliezer Liebman, author of Naḥlat Binyamin (Amsterdam, 1682), rabbi in the mark of Brandenburg, was the brother of the court Jew Jost Liebmann, who played a prominent part in the congregation of Berlin in the earliest period of its history.
Esther, the widow of Jost Liebman, fell into disfavor with Frederick William I, her property was confiscated, and she died of a broken heart in 1714.
These reverses made it impossible for Aaron to maintain his students; and the factions in the congregation of Berlin caused him constant anxiety, especially since he had always sided with his wife's family, which was very unpopular with the community.
He wrote several approbations (haskamot) to books, published in Berlin, notably that to the first edition of Samuel ben Meir's commentary on the Pentateuch (1705), the manuscript of which was in the possession of David Oppenheimer, to whom he was related by marriage.
