BiographyRichard Serra was an American minimalist sculptor renowned for his monumental works in weathered Cor-Ten steel—towering curved walls, leaning plates, and spiraling forms that transform architectural space and demand physical navigation by the viewer. His 1981 public installation Tilted Arc in New York City became one of the most contentious episodes in the history of public art when it was removed following a public outcry, raising lasting questions about site-specificity and censorship. He is widely considered one of the greatest sculptors of the 20th and 21st centuries.
