This dissertation examines the work of the San Francisco-based artist Jess (1923-2004). Jess's multimedia and cross-disciplinary practice, which takes the form of collage, assemblage, drawing, painting, film, illustration, and poetry, offers a perspective from which to consider a matrix of issues integral to the American postwar period. These include domestic space and labor; alternative family structures; myth, rationalism, and excess; and the salvage and use of images in the atomic age. The dissertation has a second protagonist, Robert Duncan (1919-1988), preeminent American poet and Jess's partner and primary interlocutor for nearly forty years. Duncan and Jess built a household and a world together that transgressed boundaries between poetry and painting, past and present, and acknowledged the limits and possibilities of living and making daily.
