Mike Kelley, the L.A.-based but internationally renowned artist, was found dead in his South Pasadena home Tuesday, police said Wednesday.
Police are still investigating and did not immediately have a cause of death.
Kelley's studio released a statement saying: "Mike was an irresistible force in contemporary art.... We cannot believe he is gone. But we know his legacy will continue to touch and challenge anyone who crosses its path. We will miss him. We will keep him with us."
