Kathy Acker was an American experimental novelist, poet, playwright, essayist, critic, performance artist, and postmodernist writer, known for her idiosyncratic and transgressive writing that dealt with complex themes such as childhood trauma, sexuality, language, identity, and rebellion. Her writing incorporates pastiche and the cut-up technique, involving cutting-up and scrambling passages and sentences; she also defined her writing as existing in the post-nouveau roman European tradition. In her texts, she combines biographical elements, power, sex and violence.
