The Jewish Encyclopedia of Western Pennsylvania is a descriptive record of Jewish history in Western Pennsylvania. Using archival materials found in the collections of the Rauh Jewish Archives, as well as links to other repositories and resources, this online encyclopedia provides basic information about hundreds of Jewish people, families, congregations, organizations, charities, businesses, and events going back to 1755.

The Rauh Jewish Archives was founded on November 1, 1988 to collect and preserve documentation of the Jewish experience in Western Pennsylvania and to make those materials widely available to the general public.
