Allan Kaprow is considered to be the father of Happening because he was the first artist to create and perform a Happening in 1959.

Happening is characterized by audience participation, surprise and spontaneity, and its ephemeral nature.

Claes Oldenburg is known for his Happenings that involved food, such as his "The Store" (1961), where he sold food items as art objects.

Happening and Fluxus are two distinct art movements, although they share some similarities, such as their emphasis on audience participation and their ephemeral nature.

Happening is characterized by its ephemeral nature, meaning that it is not meant to be permanent.

The audience in Happening is not just a passive observer, but an active participant who is encouraged to interact with the artists and the performance.

Allan Kaprow's "18 Happenings in 6 Parts" (1959) is considered to be the first Happening.

Happening marked the beginning of performance art, challenged traditional notions of art, and opened up new possibilities for artistic expression.

Andy Warhol is not associated with Happening. He is more closely associated with Pop Art.

Happening continues to influence contemporary art, particularly performance art. Many contemporary artists have been inspired by the ideas and practices of Happening.
