Modern theatrical improvisation games began as drama exercises for children, which were a staple of drama education in the early 20th century thanks in part to the progressive education movement initiated by John Dewey in 1916.

How did improvisation begin?

In all likelihood, improvisation began in prehistory, with two cavepeople trying to explain to another caveperson what they were doing in each other's cavebeds. The earliest recorded example comes from the fourth century BC.

Who founded improvisation?

Its start in 1963, though, was anything but legendary. The Improvisation was founded in New York City by Broadway producer Budd Friedman.
