Richard Serra (November 2, 1938 – March 26, 2024) was an American artist known for his large-scale abstract sculptures made for site-specific landscape, urban, and architectural settings, whose work has been primarily associated with Postminimalism. Described as "one of his era's greatest sculptors", Serra became notable for emphasizing the material qualities of his works and exploration of the relationship between the viewer, the work, and the site.
