Donna Leon (; born September 28, 1942, in Montclair, New Jersey) is the American author of a series of crime novels set in Venice, Italy, featuring the fictional hero Commissario Guido Brunetti.
Leon lived in Venice for over 30 years and now resides in a small village in Switzerland. She also has a home in Zurich. She was a lecturer in English literature for the University of Maryland University College – Europe (UMUC-Europe) in Italy and then worked as a professor from 1981 to 1999 at the American military base of Vicenza, Italy. She has stopped teaching and concentrated on writing and other cultural activities in the field of music (especially baroque music).Her Commissario Brunetti novels all take place in or around Venice. They are written in English and have been translated into many foreign languages, but–at Leon’s request–not into Italian. The ninth Brunetti novel, Friends in High Places, won the Crime Writers’ Association Silver Dagger in 2000. German television has produced 22 Commissario Brunetti episodes for broadcast.
