R. Jacob ben Samuel Bunim Koppelman (1555–1594) was born in Brisk, Poland. He was a Talmudic scholar, the student of R. Mordecai ben Abraham Jaffe (Levush, c. 1535-1612) and also studied astronomy and mathematics. R. Koppelman afterwards went to Frankfort on the Main to establish a yeshivah but was forced to leave that city in 1583 on account of the plague. He was associated with the press in Freiburg where he was the translator of Mishlei Shu’anlim (1583) and the Targum to the five Megillot (c. 1585). He was also the author of Ohel Ya’akov (Freiburg, 1584).
