Sophie Calle (born 9 October 1953) is a French writer, photographer, installation artist, and conceptual artist. Calle's work is distinguished by its use of arbitrary sets of constraints, and evokes the French literary movement known as Oulipo. Her work frequently depicts human vulnerability, and examines identity and intimacy. She is recognized for her detective-like tendency to follow strangers and investigate their private lives. Her photographic work often includes panels of text of her own writing. Since 2005 Calle has taught as a professor of film and photography at European Graduate School in Saas-Fee, Switzerland. She has lectured at the University of California, San Diego in the Visual Arts Department. She has also taught at Mills College in Oakland, California. Exhibitions of Calle's work took place at the Centre Georges Pompidou, Paris; Hermitage Museum, St. Petersburg, Russia; Musée d'Art et d'Histoire du Judaïsme, Paris; Paula Cooper Gallery, New York; Palais des Beaux-Arts, Brussels, Belgium; Videobrasil, SESC Pompeia, São Paulo, Brazil; Museum of Modern Art of Bahia, Salvador, Brazil; Whitechapel Gallery, London; and the De Pont Museum of Contemporary Art, Tilburg, Netherlands. She represented France at the Venice Biennale in 2007. In 2017 she was shortlisted for the Deutsche Börse Photography Prize for her publication My All (Actes Sud, 2016). In 2019 she was the recipient of the Royal Photographic Society's Centenary Medal and Honorary Fellowship. Works 1979–1981 In Suite Venitienne (1979), Calle followed a man she met at a party in Paris to Venice, where she disguised herself and followed him around the city, photographing him. Calle's surveillance of the man, who she identifies only as Henri B., includes black and white photographs accompanied by text. Calle's first artistic work was The Sleepers (Les Dormeurs), a project in which she invited passers-by to occupy her bed. Some were friends, or friends of friends, and some were strangers to her. She served them food and photographed them every hour. In order to execute her project The Hotel (1981), she was hired as a chambermaid at a hotel in Venice where she was able to explore the writings and objects of the hotel guests. Insight into her process and its resulting aesthetic can be gained through her account of this project: "I spent one year to find the hotel, I spent three months going through the text and writing it, I spent three months going through the photographs, and I spent one day
