Weibel studied medicine, literature, film, philosophy and mathematics (gaining his doctorate in modal logic) in Vienna and Paris. As of 1965 involvement with “Wiener Aktionismus”, a term coined by him. In the 60s, radical, body-related and socially critical actions. In 1968 Peter Weibel took part in the action “Art and Revolution” in a lecture-hall at Vienna University, where he held a speech with a burning glove against the then government. His work, that was set in the fields of concept art, performance, video art and film, may be summed up as “media art”.
The film medium is incorporated in Weibel’s works in order to explore the problem of the object and its depiction, production and reproduction. In the 70s he turned to media-centred works and works involving audience participation. Weibel’s interdisciplinary artistic activities were based on an all-embracing definition of the concept of medium (from panel painting to screen, from text to body). He saw film, video and computer as extensions of communicative possibilities of expression. His objects and installations reflect a search for new media, methods and materials. The artist focuses on the semiotic aspects of a wide range of materials such as wood, stone and light and also integrates the significance of characters in the work.
In his works the artist explored in depth the art industry and its possibilities and limitations. In 1972 his TV action teleaktionen was broadcast on the “Impulse” programme on Austrian television (ORF). With this work Weibel transcended the traditional exhibition space such as galleries or museums, experimenting with the effect of video technology in the mass medium of television.
