Frank Stella is an American artist born in 1936 in Massachusetts. He studied painting at Phillips Academy and graduated from Princeton University. Stella lives in New York City and is known for his minimalist and abstract paintings that use simple geometric shapes and repetitive lines. In the 1960s, Stella focused on flat, two-dimensional canvases but in the 1980s his work became more sculptural and three-dimensional. Some of his most notable series include works based on circles from the 1970s called the Protractor Series. Stella continues to experiment with form and push the boundaries of abstract art.
