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.
Later, material conditions forced him to accept the position of Rabbi of Nasielsk, where he founded a yeshiva.
[2] 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 School), and the entry of Jews to the National Guard in 1831 (due to the necessary condition of shaving their beards and payot).
[3] He was buried in the Jewish cemetery in Warsaw where an ohel was erected above his grave.
