Roman Vishniac was a Russian-American photographer, best known for capturing on film the culture of Jews in Central and Eastern Europe before the Holocaust. A complete archive of his work now rests at the International Center of Photography. Vishniac was a versatile photographer, an accomplished biologist, an art collector and teacher of art history. He also made significant scientific contributions to photomicroscopy and time-lapse photography. Vishniac was very interested in history, especially that of his ancestors, and strongly attached to his Jewish roots; he was a Zionist later in life. Roman Vishniac won international acclaim for his photos of shtetlach and Jewish ghettos, celebrity portraits, and microscopic biology.
