Cäcilia Rentmeister is a German art historian, author, and feminist scholar whose work helped shape the intellectual foundations of the 1970s German women's and lesbian movements. With her partner, filmmaker Cristina Perincioli, with whom she has worked since 1973, she co-wrote Anna und Edith (1975), the first feature film about a lesbian relationship broadcast on German television — the story of two colleagues who fall in love with each other in the midst of a labor dispute. In the 1970s and 1980s she published influential and controversial essays on feminist aesthetics and women's art, and from the mid-1980s she and Perincioli turned to the theme of computers and creativity, later editing and managing web projects on social and gender subjects. Though screenwriting was a single chapter of her career, its landmark status — bringing lesbian love to a mainstream German television audience decades ahead of its time — secured her a lasting place in queer film history.
