Bruce Nauman was one of the most prominent, influential, and versatile American artists to emerge in the 1960s. Although his work is not easily defined by its materials, styles, or themes, sculpture is central to it, and it is characteristic of Post-Minimalism in the way it blends ideas from Conceptualism, Minimalism, performance art, and video art. The revival of interest in Marcel Duchamp in the 1960s also clearly influenced Nauman in various ways, from encouraging his love of wordplay to infusing his work with a satirical and sometimes absurdist tone. Despite the impact of Dada, however, he has continued to view his art less as a playful or creative enterprise than as a serious research endeavor, one he likes to carry out in seclusion from the art world, one that is shaped by his interests in ethics and politics.
