Primary Structures: Younger American and British Sculptors was an exhibition presented by the Jewish Museum in New York City from April 27 to June 12, 1966. The show was a survey of recent work in sculpture by artists from the Northeast United States, California and Great Britain that shared general characteristics of scale, simplified geometry and smooth, often colorful, industrial surfaces. Its legacy, which focuses on a subset of the artists in the show, is as the exhibition that introduced Minimal Art to a broad public, both through the exhibition itself, and the wide attention it received in national media. Primary Structures was organized by Kynaston McShine, the Jewish Museum's Curator of Painting and Sculpture.
