Yaakov Yitzchak of Lublin

Yaakov Yitzchak HaLevi Horowitz , known as "the Seer of Lublin" , ha-Chozeh MiLublin; (c. 1745 - August 15, 1815) was a Hasidic rebbe from Poland.

He was a disciple of the Maggid of Mezritch. He continued his studies under Shmelke of Nilkolsburg and Elimelech of Lizhensk. He lived for a while in Lantzut before moving to Lublin.

After Horowitz moved to Lublin, thousands of Hasidim flocked to learn from him. Among his disciples were such Hasidic luminaries as Yaakov Yitzchak Rabinowicz ("the Holy Jew"), Simcha Bunim of Peshischa, Meir of Apta, David of Lelov, Moshe Teitelbaum, Tzvi Elimelech of Dinov, Naftali Zvi of Ropshitz, and Shalom Rokeach of Belz. Rabbi Yaakov Yitzchak was known as the "Seer of Lublin" (Chozeh MiLublin) due to his reputed prophetic insight and spiritual vision. His disciples, followers, and contemporaries testified that he possessed the ability to perceive realities beyond the physical realm — across spatial dimensions such as distance, height, and depth, as well as temporal dimensions, including past and future events. Witnesses also attributed to him the capacity to discern people's innermost thoughts, words, and hidden actions. He was further described as having visions of spiritual worlds, including Heaven, Hell, reincarnated souls, and angels. His students regarded him as a figure akin to a biblical prophet. During his stay in Lublin, Horowitz was opposed by a prominent mitnaged rabbi, Azriel Horowitz. Even after Horowitz's death the synagogue remained the heart and soul for the scholars of the city. During the war the building was demolished to the ground, and was never rebuilt. Lately the Lublin Organization in New York made an attempt to restitute the property in order to rebuild the synagogue in remembrance of Rabbi Horowitz, but their efforts were unsuccessful.

Horowitz was a descendant of Isaiah Horowitz, a prominent rabbi and mystic, from injuries relating to this fall. He is buried in the Old Jewish Cemetery, Lublin. His great grandson was Rabbi Kalonymus Kalman Shapira of Piaseczna.
