Roman Signer (born in 1938 in Appenzell, lives and works in Saint-Gall), who represented Switzerland in the 48th Venice Biennale in 1999, is famous for his « interventions » consisting of actions and performances that explores physic laws of natural elements such as wind, weight falling or river stream power. These works, mostly ephemeral, in which the artist often takes actively part, might articulate use of explosives, and redefine parameters of time and space within the field of sculpture. His work, made of raw quality materials of daily use, activates itself with a great sense of humor and absurdity through narrative actions, in a kind of a philosophical paradigma of the dynamic mecanisms of life.
