Ann Bannon was born Ann Weldy in Joliet, Illinois. From 1957 to 1962, as a young housewife exploring her own sexuality, she wrote five lesbian pulp novels, The Beebo Brinker Chronicles, whose cast of four recurring characters includes Beebo Brinker, who came to embody the butch lesbian archetype.
She stopped writing in 1962, later earned a doctorate in linguistics and became an academic. When the books were republished in the 1980s and again between 2001 and 2003, she was surprised to learn how much they had meant to readers. They are now taught in women's and LGBT studies courses.
