Dan Graham’s interest in the social implications of systems, popular culture, and architecture is articulated in his installations, conceptual pieces, performances, videos, architectural designs, and prolific writing. Graham began using video as a medium in the 1970s as a way to engage his viewers directly, while attempting to restructure perceptions of time and space—a motive carried into his later glass and mirror pavilions. Circularity and feedback are major themes in Graham’s works, evidenced by his frequent use of mirrors, participation, and sometimes two cameras to create a loop. His influences include Larry Bell, Robert Mangold, Sol LeWitt, and Mies van der Rohe. In spite of his contributions to the legacy of media and installation art, Graham is still uncomfortable considering himself a professional artist.
