1579 - 1654 (6 Elul 5414) YOM TOV LIPMANN HELLER (Wallerstein-Cracow, Poland)
Scholar and historian. He served as the rabbi of many communities including Nikolburg, Vienna and Prague. Heller was very active in community affairs, and because of this was once denounced as an author of anti-Christian writings. Although the charges were baseless (he had written about idolaters during the time of the Temple), he was forced to move. He is best known for his commentary on the Mishna called Tosaphot Yom Tov (Supplements of Yom Tov). He later became Rabbi of Cracow.
