'''Julius (Judah David) Eisenstein''' (November 12, 1854–May 17, 1956) ({{lang-he|'''יהודה דוד אייזענשטיין'''}}) was a Polish JewsJewish-American writer born in Międzyrzec Podlaski, a city in Biała Podlaska County, Lublin Voivodeship, Russian Poland. While in Poland, he was educated in Talmud by his grandfather, Azriel Zelig. Julius emigrated in 1872 to the United States at the age of 17, settled in New York City, and married the following year. He became a successful businessman, but lost much of his fortune in a failed effort to establish an agricultural colony for Jewish immigrants in New Jersey.
Eisenstein was a lover of the Hebrew language, and established America's first society for the Hebrew language, called ''Shocharei Sfat Ever''. He was also the first to translate into Hebrew and Yiddish the Constitution of the United States (New York, 1891). Other early writings of his are ''Ma'amare Bamasoret,'' ib. 1897, and ''The Classified Psalter'' (Pesuke de-Zimrah), Hebrew text with a new translation (1899). He also made an attempt to translate and explain a modified text of the ''Shulhan 'Arukh''.
