Resettled in Los Angeles in 1943 on contract with MGM (Loring had a feature role in "National Velvet" even before he choreographed for them), he turned his attention to regularizing and applying his principles of versatile "Freestyle" professional dance education, including (from 1955) his own dance notation, Kineseography. Loring operated the commercially successful American School of Dance in Hollywood along those principles, and from 1965 developed them in a university educational setting, on invitation by Dean Clayton Garrison to chair the Department of Dance within the School of Fine Arts of the newly formed University of California, Irvine. Loring retired from UCI in 1981, returned to New York State but died a year later, aged seventy-one.
