Temple Emanu-El of New York was the first Reform Jewish congregation in New York City and, because of its size and prominence, has served as a flagship congregation in the Reform branch of Judaism since its founding in 1845. Its landmark Romanesque Revival building on Fifth Avenue is one of the largest synagogues in the world. In size, it rivals many of the largest European synagogues such as Grand Choral Synagogue of St. Petersburg, Moscow Choral Synagogue, and the Budapest Great Synagogue.Emanu-El means "God is with us" in Hebrew.
The congregation currently comprises approximately 3,000 families and has been led by Senior Rabbi Joshua M. Davidson since July 2013. The congregation is located at 1 East 65th Street on the Upper East Side of Manhattan. The Temple houses the Bernard Museum of Judaica, the congregation's Judaica collection of over 900 objects.
The congregation was founded by 33 mainly German Jews who assembled for services in April 1845 in a rented hall near Grand and Clinton Streets in Manhattan's Lower East Side. The first services they held were highly traditional. The Temple (as it became known) moved several times as the congregation grew larger and wealthier.
In October 1847, the congregation relocated to a former Methodist church at 56 Chrystie Street. The congregation commissioned architect Leopold Eidlitz to draw up plans for renovation of the church into a synagogue. Radical departures from Orthodox religious practice were soon introduced to Temple Emanu-El, setting precedents which proclaimed the principles of 'classical' Reform Judaism in America. In 1848, the German vernacular spoken by the congregants replaced the traditional liturgical language of Hebrew in prayer books. Instrumental music, formerly banished from synagogues, was first played during services in 1849, when an organ was installed. In 1853, the tradition of calling congregants for aliyot was abolished (but retained for bar mitzvah ceremonies), leaving the reading of the Torah exclusively to the presiding rabbi. By 1869 the Chrystie Street building became the home of Congregation Beth Israel Bikur Cholim.
