From his photo-text canvases in the 1960s to his video works in the 1970s to his installations in the 1980s, John Baldessari’s (b.1931) varied work has been seminal in the field of conceptual art. Integrating semiology and mass media imagery, he employed such strategies as appropriation, deconstruction, decontextualization, sequentiality, and text/image juxtaposition. With an ironic wit, Baldessari's work considers the gathering, sorting, and reorganizing of information.
