Peter Fischli (born 8 June 1952) and David Weiss (21 June 1946 – 27 April 2012), often shortened to Fischli/Weiss, were an artist duo that had been collaborating since 1979. They were among the most renowned contemporary artists of Switzerland.
Their best-known work is the film Der Lauf der Dinge (The Way Things Go, 1987), described by The Guardian as being “post apocalyptic”, as it concerned chain reactions and the ways in which objects flew, crashed and exploded across the studio in which it was shot. Fischli lives and works in Zurich; Weiss died on 27 April 2012.
