Una Chi (born Bruna Bianchi, Milan, 1942) is an Italian writer and translator. A strong erotic identity is manifest in her works and she is distinguished, among other characteristics, by her scholarly and coldly analytical prose and the cruelty of her stories.
Born in Milan in 1942, Bruna Bianchi now teaches German literature at the University of Milan. She is also a translator of Goethe and Thomas Mann. In the early 1990s, she drew the attention of critics and the public with the publication of some erotic novels, that she publishes under the pseudonym Una Chi (probably to preserve even more anonymity, because this name means One Who).
