In the late 1940s, Paolozzi spent time in Paris, France, shadowing such surrealist artists as Jean Dubuffet and Alberto Giacometti. During this time, Paolozzi started making sculptures and collages that uniquely combined the influences of surrealism with elements of popular culture and contemporary machinery. A collection of Paolozzi's collages, comprised of clippings he pulled from magazines American soldiers had given him in Paris, were later displayed in a slideshow at the Institute of Contemporary Arts in 1952. To many, the slideshow designated Paolozzi as the "inventor of Pop Art."
Throughout his career as an artist, Paolozzi would teach at a number of art institutions, including his alma mater, St. Martin's School of Art
Paolozzi spent much of the 1970s working on abstract art, including screen printing and reliefs. His color schemes were largely monochromatic during this time—a major departure from his previous, colorful work. One formidable product of this stage in Paolozzi's career was a commission of panels for the ceiling of Cleish Castle in Kinross-shire, Scotland.(.biography.com)
