The Open Siddur Project is a volunteer-driven collaboration between folk passionate about Jewish spiritual practice. Some are interested in the Siddur as a technology for preserving and disseminating an evolving history of Jewish ritual, practice, and sacred poetry. Others are energized by the design challenge of crafting Siddurim that function effectively for nurturing spiritual, emotional and creative intelligence. All of us see the potential that creative engagement holds for empowering students and teachers to take ownership of those ingredients comprising their shared cultural inheritance.

The Open Siddur is a non-prescriptive, non-denominational project whose only intent is to help revitalize Judaism by ensuring its collective spiritual resources — the creative content intended for communal use — remain free for creative reuse. The Open Siddur Project invites participation without prejudice towards ethnic heritage, skin color, nationality, belief or non-belief, sex, gender, sexuality or any other consideration. All we ask for is an intellectually honest commitment to the principles and sensibilities preserved in our mission statement.

He is best known to the general public for his mass–energy equivalence formula E = mc^2, which has been dubbed "the world's most famous equation."

Judah David Eisenstein (translation)
Julius (Judah David) Eisenstein (November 12, 1854 – May 17, 1956) (יהודה דוד אייזנשטיין‎) was a Polish-Jewish-American anthologist, diarist, encyclopedist, Hebraist, historian, philanthropist, and Orthodox polemicist born in Międzyrzec Podlaski (known in Yiddish as Mezritch d'Lita), a town with a large Jewish majority in what was then Congress Poland. He died in New York City at the age of 101. Eisenstein was a lover of Hebrew, and established America's first society for the Hebrew language, Shoharei Sfat Ever. He was also the first to translate the Constitution of the United States into Hebrew and Yiddish (New York, 1891). Other early writings of his are Ma'amarei BaMasoret, ib. 1897, and The Classified Psalter (Pesukei dezimra), Hebrew text with a new translation (1899). He also made an attempt to translate and explain a modified text of the Shulchan Aruch. He was known by many colleagues as the Ba'al ha-Otzrot ("Master of the Anthologies"). His works remain standard reference books in yeshivot, batei midrash, synagogues, and Jewish libraries to this day. (adapted from the article, "Julius Eisenstein," in Wikipedia)
