Barbara Hammer (1939-2019) was an American feminist filmmaker, visual artist, and lesbian activist with a career spanning over fifty years—constructing revelations on gender and sexuality, and later illness and mortality. She produced over ninety films, ranging from experimental shorts to essays and full-length documentaries, as well as performances, installations, and photographs that illuminate the representation of lesbian lives. In her work, Hammer explodes traditional notions of female sexuality by showing it for what it is: complex, messy, human.
