Mierle Laderman Ukeles is an artist known for her exploration of feminist, labor, and ecological themes. Since 1977, she has created art that deals with the endless maintenance and service work that “keeps the city alive,” urban waste flows, recycling, ecology, urban sustainability and our power to transform degraded land and water into healthy public places. Since the late 1980s, much of Ukeles’ work has been created through “I-II: Infrastructure Interface Inc,” her conceptual organization, focused on transforming closed landfills into urban parks, with her Percent for Art commission for Fresh Kills in Staten Island, New York since 1989, once the largest municipal landfill in the world, at Danehy Park in Cambridge since 1990, and in Evapotranspiration for Hiriya, an installation at the Tel Aviv Museum proposed for Israel’s largest landfill.
