Peter Fischli (8 June 1952 in Zurich) and David Weiss (21 June 1946 in Zurich), often shortened to Fischli/Weiss, are an artist duo that have been collaborating since 1979. They are among the most renowned contemporary artists of Switzerland. For their work, they make use of a large bandwidth of artistic forms of expression: Film and photography, art-books, sculptures made out of different materials, and multimedia-installations. They adapt objects and situations of the everyday life and place them into an artistic context — often using humour and irony.
