R.G. Davis founded the company that became the San Francisco Mime Troupe as an experimental project of the Actors' Workshop in 1959. He left the Troupe in 1970, formed the Epic West Center in Berkeley for the study of Bertolt Brecht and epic theatre, and became a pioneering director in the United States successively of the plays of Brecht and Dario Fo, on which he wrote in the original Theatre Quarterly 40 (Autumn–Winter 1981) and in New Theatre Quarterly 8 (November 1986). In this article he traces the course of his subsequent career in creating experimental storytelling events and, via an interlude garnering academic qualifications, into the field of ecological aesthetics, which he defines as ‘a Brechtian aesthetic and ecological socialism interrogating each other within a scientific ecological conception of nature’. The present article is based on a lecture he gave in June 2013 at Stanford University.
