1470 - 1541 (23 Sivan 5301) JACOB POLLACK (Prague-Cracow-Eretz Israel)
The first important Polish-Jewish Rabbinic scholar. He helped establish the talmudic method of study called Pilpul. This complicated and often hair-splitting method of explanation originated in southern Germany. It is called mental acrobatics by some, yet it was also responsible for the development of the sharp talmudic mind.
