The Congregation Gates of Prayer was organized in the "Old Lafayette" area of New Orleans in 1849 and incorporated in 1850. The Congregation later moved to Jefferson Parish and established a new synagogue in Metairie. It followed the Orthodox tradition and services were conducted by a cantor for many years. At the turn of the century, the influence of the Reform movement was felt, and in 1906 the first rabbi was engaged.
The collection consists of the Congregation Gates of Prayer's by-laws, constitutions, financial and property records, correspondence, pamphlets, charter amendments, congregation history, minute books, programs, telegrams, bulletins, newspaper clippings, and scrapbooks. The scrapbooks were created by Daniel B. Alexander of New Orleans, Louisiana, during his service as Secretary of the Congregation. They include information about the history of the congregation and include newspaper clippings, congregation bulletins, programs, photographs, and other items. They also contain materials concerning Alexander's personal interests, American-Israeli relations and Jewish history in particular.
