Rabbi Naftali Halberstam, the Rebbe of Gribov, was the firstborn son of Rabbi Baruch, Av Beis Din of Gribov and the youngest rabbi of the Sanz community.

Rabbi Naftali was born in 1924 in Sanz. He merited to know his grandfather Rabbi Aryeh Leibush of Sanz. In 1939, when war broke out, he fled with his mother to Lemberg together with his grandfather Rabbi Sinai Halberstam of Zmigrod. From there he was exiled to Siberia where, with great mesiras nefesh, he did not eat non-kosher food or desecrate Shabbos. Throughout the war, he kept the tefillin he received from his father for his Bar Mitzvah. He survived the Holocaust and immigrated to the United States, settling in Boro Park. He studied in the Lubavitch Yeshiva under the Frierdiker Rebbe and married the daughter of Rabbi Lipa Mann, Av Beis Din of Bekitshev.
