The first public "happening" was produced by Allan Kaprow in 1959 at the Reuben Gallery in New York.
Happenings were influenced by Jackson Pollock's process of action painting, Dada and the teachings of John Cage on chance and indeterminacy. Kaprow defines "а happening" as a choreographed event that facilitates interactions between objects including performers and visitors.
