He was born to Rabbi Yaakov Eisenstadt in Białystok, in the Russian Empire, in 1813 , a descendant of Rabbi
Meir Eisenstadt, author of the responsa Panim Me’irot. At the age of 15, he married Yenta Reizel, daughter of Yehuda Leib HaKohen of Grodno, and lived with her in Białystok. His wife was engaged in commerce and ran a shop selling paper goods and writing instruments, while he devoted himself to Torah study in the beit midrash of Rabbi Yechiel Neches, along with Rabbi Shmuel HaLevi (author of Bigdei Yesha) and Rabbi Gershon Chen-Tov (author of Mincha Chadasha). The shop’s main customers were government institutions in the city. A few years later, when the government offices moved to Grodno, the couple relocated there as well. However, their business did not succeed in the new location, and in order to support his family, Rabbi Eisenstadt accepted a position as a dayan (rabbinical judge) in the city for several years. In 1836, he was chosen to serve as the rabbi of Bristovitz in the Grodno district. From there, he went on to serve as the rabbi of Utyan (
Utena) in the Kovno region. In the winter of 5628, he traveled to Königsberg on the Baltic coast for medical treatment. He died there on the 3rd of Elul that same year (1868). He was buried there, between Rabbi
Yehuda Ashkenazi of Tykocin, author of
Be’er Heitev, and Rabbi Yaakov Tzvi Mecklenburg, author of HaKetav VeHaKabbalah. ==Works==
