According to publisher Ian Sternthal, who published several portraits of Hannah Arendt on his website (last accessed March 10, 2017 http://sternthalbooks.com/journal/a-letter-from-hannah-arendt-to-gershom-scholem/), including the same image depicted in the New School Archives' oversize print, Sternthal obtained the prints from New School for Social Research professor Richard Bernstein. The photographer is unknown.

E-mail communication from Ian Sternthal to the New School Archives, February 12, 2014.

The 1971 photograph of Arendt may have been taken at the Graduate Faculty conference,"Weimar Germany 1919-1932: Intellectuals, Culture and Politics."
