Congregation Ohab Zedek, was founded in 1873 on the Lower East Side. The congregation built a synagogue building at 70 Columbia Street in 1881. In 1886 the congregation sold the Columbia Street building to Congregation Ahavath Acheim Anshe Ungarn and moved into the gothic-style synagogue building 172 Norfolk Street that is now the Angel Orensanz Center, the oldest surviving synagogue building in New York and the fourth-oldest in the United States.
In 1906–07 the congregation built and moved into a "monumental" building on 116th Street, in the newly fashionable neighborhood of Harlem. The "monumental" design was influenced by the Gothic character of the previous Norfolk Street home. The street-facing gable prominently featured a large four-centered arch-headed window over a large pedimented doorcase, appearing styled in loose or Vernacular Gothic on the interface of Moorish Revival architecture. The famous singer Yossele Rosenblatt was a cantor there from 1911 to 1926, and again in 1929. In 1926 O.Z. moved to its present building at 118 West 95th Street; the 116th Street property was sold, eventually becoming the Baptist Temple Church, which occupied the location for over five decades. Conversion into a church removed the Jewish-themed terracotta ornaments. Costly structural damage necessitated the building's demolition, which occurred slowly throughout late 2009 and early 2010.
Current building, West 95th Street
The current synagogue building at 118 West 95th Street is noted for its Moorish Revival architecture. Designed by architect Charles B. Myers, the interior features magnificent Mudéjar style plasterwork. The building was listed on the National Register of Historic Places in 2017.
Early in the 21st century, the congregation became known for attracting large numbers of orthodox Jewish singles to its services and programs. The congregation published a book in 2005 about its history, First Hungarian Congregation Ohab Zedek, written by O.Z. member Chaim Steinberger. Currently, the senior Rabbi is Allen Schwartz and the Executive Director is Chad Hopkovitz.
