Katharina Eleonore Behrend (July 22, 1888 – November 15, 1973) was a German-born Dutch photographer who is remembered for her work in a wide variety of photographic genres including a nude self-portrait.
Born in Leipzig, she grew up in a well-to-do family as the daughter of Robert Behrend, a chemistry professor, later moving to Hanover.
In 1930, when she started using a Zeiss Ikon Ikonta, she stopped keeping detailed records.
In addition to photographs of family and friends, there are views of Algeria (1905–06), including the temple ruins at Timgad, and of her husband's factory (1913–1915).
There are also nude photographs of herself and her friends (1910–11) at a time when she supported the German Freikörperkultur movement.
