Mierle Laderman Ukeles's manifesto ''Maintenance Art--Proposal for an Exhibition'' (1969) was a major intervention in feminist performance practices and public art. The proposal argued for an intimate relationship between creative production in the public sphere and domestic labor--a relationship whose intricacies Ukeles has been unraveling ever since. In 1977, she became the unsalaried Artist-in-Residence for the New York City Department of Sanitation, a position that enables her to introduce radical public art into an urban municipal infrastructure.
