Claes Oldenburg was born January 28, 1929 in Stockholm, Sweden. He is a sculptor, best known for his public art installations typically featuring very large replicas of everyday objects. Another theme in his work is soft sculpture versions of everyday objects.

Claes Oldenburg is the son of a Swedish diplomat. As a child he and his family moved to United States in 1936, first to New York then, later, to Chicago where he graduated from the Latin School of Chicago. He studied at Yale University from 1946 to 1950, then returned to Chicago where he studied under the direction of Paul Wieghardt at the Art Institute of Chicago until 1954.

The most memorable aspects of Oldenburg's works are perhaps, the colossal sculptures that he has made. Sculptures, though quite large, often have interactive capabilities. One such interactive early sculpture was a soft sculpture of a tube of lipstick which would deflate unless a participant re-pumped air into it. In 1974, OLdenburgs' sculpture, Lipstick (Ascending) on Caterpillar Tracks, was redesigned in a sturdier aluminum form, the giant lipstick being placed vertically atop tank treads. Originally installed in Beinecke Plaza at Yale, it now resides in the Morse College courtyard.

In the 1960s he became associated with the Pop Art movement and attended many so-called happenings, which were performance art related productions of that time. The name he gave to his own productions was "Ray Gun Theatre". Oldenburg's spirited art found first a niche then a great popularity that endures to this day.
