Rabbi Shabsai Bass

Shabbethai ben Yosef Bass was the founder of Jewish bibliography and author of the *Siftei Chachamim*, a supercommentary on Rashi's Torah commentary. He established the first Hebrew printing press in Dyhernfurth in 1689 and published numerous Jewish works there over nearly three decades. His *Siftey Yeshenim* provided the initial comprehensive listing of Hebrew printed books.
