Photographer Roman Vishniac's vast archive of images of pre-Holocaust Eastern European Jewish life is being made available to the public and researchers.

The International Center of Photography in New York and the United States Holocaust Memorial Museum in Washington, D.C. Monday announced the joint creation of a digital database to facilitate access to the archive.

Vishniac was a Russian-born Jew who immigrated to Berlin in 1920. As an avid photographer, he documented the ominous rise of Nazi power and its effect on everyday Jewish life in Central and Eastern Europe.

The database includes all of Vishniac's 9,000 negatives, most of which have never before been printed or published.

ICP and the museum are also asking scholars and the public to help identify the people and places depicted in the images.
