Katherine Murray Millett was an American feminist writer, educator, artist, and activist. She attended the University of Oxford and was the first American woman to be awarded a degree with first-class honors after studying at St Hilda's College, Oxford. She has been described as "a seminal influence on second-wave feminism", and is best known for her book Sexual Politics (1970), which was based on her doctoral dissertation at Columbia University. Journalist Liza Featherstone attributes the attainment of previously unimaginable "legal abortion, greater professional equality between the sexes, and a sexual freedom" in part to Millett's efforts.

St Hilda's College is one of the constituent colleges of the University of Oxford in England. The college is named after the Anglo-Saxon saint Hilda of Whitby and was founded in 1893 as a hall for women; it remained a women's college until 2008. St Hilda's was the last single-sex college in the university as Somerville College had admitted men in 1994. The college now has almost equal numbers of men and women at both undergraduate and postgraduate level.
