Alvy Ray Smith
Smith and Catmull co-founded Pixar in 1986 with financing from Steve Jobs. After the spinout from Lucasfilm of Pixar, he served on the board of directors and was executive vice president. According to the Steve Jobs biography "iCon" by Jeffrey S. Young and William L. Simon, Alvy Ray quit Pixar after a heated argument with Jobs over use of a whiteboard. It was an unwritten rule that none other than Jobs was allowed to use it, a rule Smith decided to break in front of everyone after Jobs went "total street bully" on him and they ended up screaming into each other's face "in full bull rage". Despite being the co-founder of Pixar, Young and Simon claim that the company has largely overlooked his part in company history since his departure. For example, there is no mention of Smith on the Pixar website.
Ralph Guggenheim
After his time at CMU, Ralph worked for the New York Institute of Technology Computer Graphics Lab. He was soon contacted by Lucasfilm and moved to California in 1980. During his time at Lucasfilm, Guggenheim developed EditDroid, which proved to be a revolutionary film-editing system. After his research lab at Lucasfilm was sold to Steve Jobs and renamed Pixar, Guggenheim continued to work in the world of graphics and animation. Guggenheim, a respected founder of Pixar, eventually became Vice President of Feature Animation and was a lead producer for "Toy Story." Guggenheim left the company in 1997 after Disney forced Pixar to remove him as producer from "Toy Story 2".
