Famed American abstract artist and sculptor Ellsworth Kelly passed away Sunday at his home in Spencertown, New York. He was 92.

Influenced by Picasso and Matisse, Kelly studied art in Paris on the GI Bill after serving in World War II.

“In his work Kelly abstracts the forms in his paintings from observations of the real world, such as shadows cast by trees or the spaces between architectural elements,” reads the Guggenheim's biography of the artist.

Kelly had numerous retrospectives and major exhibitions over his decades-long career, with highlights including New York’s Guggenheim Museum and the San Francisco Museum of Modern Art.
