Szlomo Zalman Lipszyc
Szlomo Zalman Lipszyc (1765 Poznań - 1839 Warsaw), also known as Salomon Zalman Pozner as well as the Chemdas Shlomo from the title of the works he authored, was a prominent Orthodox rabbi, and first Chief Rabbi of Warsaw. He studied Torah in his hometown of Poznań until 1804. Later, material conditions forced him to accept the position of Rabbi of Nasielsk, where he founded a yeshiva. In 1819 he became Rabbi of Praga near Warsaw, and in 1821 he was elected the first Chief Rabbi of Warsaw. As chief rabbi, he did not become involved in the  disputes of Misnagdim with the Hasidim. He opposed assimilation, condemning the Haskala's Szkoła Rabinów w Warszawie (Warsaw Rabbinical Seminary), and the entry of Jews to the National Guard in 1831 (due to the necessary condition of shaving their beards and payot). Many Polish rabbis studied in his Warsaw yeshiva. He was a prominent halakhic authority and the author of three works entitled Chemdas Shlomo: rabbinical responsa (1839), novellae to several Talmudic treatises (vol. 1-3, 1851-1892) and sermons (1890). He carried on a scientific correspondence with Rabbi Akiva Eger and Rabbi Jacob of Lissa. He was buried in  the Jewish cemetery in Warsaw where an ohel was erected above his grave. Grandson Mojżesz Lipszyc was a rabbi in Golub-Dobrzyń, and then in Łódź, where later also his great-grandson, Natan Lipszyc, held rabbinical functions.
