Anna Halprin (born Anna Schuman on 13 July 1920) helped pioneer the experimental art form known as postmodern dance and referred to herself as the breaker of modern dance. Halprin, along with her contemporaries such as Trisha Brown, Simone Forti, Yvonne Rainer, John Cage, and Robert Morris, collaborated and built a community based around the fundamentals of post-modern dance.
