This collection contains the records of the Society for the History of Czechoslovak Jews, an organization founded in 1961, in New York City, by members of the Joseph Popper unit of B’nai B’rith, to foster and disseminate knowledge about the history and culture of Jews in the Czech and Slovak lands. Along with the Joseph Popper unit and, later, the Holocaust Survivors of Slovakia, the society sponsored an annual memorial service held in New York City to honor Czechoslovak Jews who perished in the Holocaust. A majority of the records are from the tenure of Rabbi Norman Patz as president (1994-2008). The materials primarily comprise correspondence, and items related to the annual memorial service, including texts of addresses, and yizkor memorial booklets. Also included are meeting minutes, letters to the membership, financial reports, writings, speeches, obituaries, clippings, photographs, and printed ephemera. The society's correspondence reflects its participation in cultural events related to Czech and Slovak Jewish history, as well as its relationship to the Jewish communities in the Czech Republic and, to a lesser extent, Slovakia; some correspondence with members contains genealogical information.

The Freedom Benevolent Society was a mutual aid and fraternal organization founded by Jewish immigrants from the Austro-Hungarian Empire in 1882, on the Lower East Side of New York City. Originally known as the Erster Kaiser Franz Josef Kranken Unterstützungs–Verein, or the First Franz Joseph Sick and Benevolent Society, it was incorporated in 1883. Its main purpose was to provide its members with sick benefits, and relief in times of need, as well as fellowship and entertainment. Eventually it also functioned as a burial society, and maintained cemetery plots. The collection documents the society's activities over more than a century, from 1884 until its initiation of dissolution proceedings, in 1991. It includes membership applications from the early decades of the society's history (1884-1927), anniversary programs spanning fifty years (1932-1982), and a visitors' register for the 1500th meeting, in 1950, as well as account books, meeting notices, and two cemetery plans, one of which relates to the Franz Joseph Ladies Sick and Benevolent Society.
