His first Happening, "The Theater is in the Street", took place in Paris in 1958, and incorporated auto parts and a TV. He was impressed by the work of Karlheinz Stockhausen, which he encountered in the electronic studios of the German radio station WDR in 1959 and he creates his electronic "TV Dé-coll/age". It marked the beginning of his dedication to the Fluxus Movement, which he co-founded in 1962. Vostell was behind many Happenings in New York, Berlin, Cologne, Wuppertal and Ulm among others. In 1962 he participated in the FLUXUS Internationale Festspiele Neuester Musik event in Wiesbaden together with Nam June Paik, George Maciunas and other artists. In 1963 Wolf Vostell became a pioneer of Video art and Installation with his work "6-TV-Dé-coll/age" shown at the Smolin Gallery in New York, and now in the collection of the Museo Reina Sofía in Madrid. The Smolin Gallery sponsored two innovative Wolf Vostell events on TV; the first, "Wolf Vostell and Television Decollage", featured visitors to the gallery who were encouraged to create poster art on the walls. In 1967 his Happening "Miss Vietnam" dealt with the subject of the Vietnam war. In 1968, he founded Labor e.V., a group that was to investigate acoustic and visual events, together with Mauricio Kagel, and others. In 1978 he met Salvador Dalí, with whom he would later create a joint project with a sculpture from each other in their museums.
