Williams studied poetry with John Crowe Ransom at Kenyon College, studied anthropology at the University of Paris, and worked as an assistant to the ethnologist Paul Radin in Switzerland.
As an artist and poet, Emmett Williams collaborated with Daniel Spoerri in the Darmstadt circle of concrete poetry from 1957 to 1959. In the 1960s, Williams was the European coordinator of Fluxus, and a founding member of the Domaine Poetique in Paris, France.
In 1996 he was honoured for his life work with the Hannah-Hösch-Preis.
