Roy E. Disney, son of Disney Studios co-founder Roy O. Disney, and nephew of Walt Disney, passed away yesterday after a year-long battle with stomach cancer.

John Lasseter, chief creative officer for Walt Disney and Pixar Animation Studios, added, “I first met Roy when I was still an animation student at CalArts. Not only did I consider him a personal friend, but he was a great man who believed deeply in the art of animation. He put his heart and soul into preserving Disney’s legendary past, while helping to move the art of animation into the modern age by embracing new technology. Roy was a visionary and passionate supporter of the art form, and he was all about quality. I was always impressed that he would make time for someone like me when I was fresh out of college, and he continued to support and encourage me throughout my career.”
