Israel Lipschitz (Hebrew: ישראל ליפשיץ (1782-1860) was rabbi and one of the Acharonim first at Dessau and then at the Jewish Community of Danzig. He was the author of Tiferet Yisrael (commentary) a well-known commentary on the Mishna. It is often referred to as "Mishnayos Yachin uBoaz." It is subdivided into two parts, one more general and one more analytical, titled "Yachin" and "Boaz" respectively (after two large pillars in the Temple in Jerusalem). This is considered to be one of the best and most useful commentaries on the Mishna. He also wrote Shevilei de'Rakiya, an introduction to the principles of Rabbinical astronomy, and Derush Ohr Ha-Hayyim (Homily on the Light of Life) which debates the eternality of the soul.
He led the life of an ascetic, frequently fasted three days in succession, and studied incessantly. His ethical will contains twenty-eight paragraphs, consisting chiefly of moral and ascetic precepts. He left in manuscript many notes ("derashot") to the Shulchan Aruch and to Maimonides Mishneh Torah, a comprehensive treatise on the order Tohorot, and many responsa.
