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.
John Lasseter
Due to George Lucas's financially crippling divorce, he was forced to sell off Lucasfilm Computer Graphics, by this time renamed the Pixar Graphics Group, founded by Smith and Catmull, with Lasseter as one of the founding employees. It was spun off as a separate corporation with Steve Jobs as its majority shareholder in 1986. Over the next 10 years, Pixar evolved from a computer company that did animation work on the side into an animation studio. Lasseter oversaw all of Pixar's films and associated projects as executive producer. As well as "Toy Story", he also personally directed "A Bug's Life" (1998), "Toy Story 2" (1999), "Cars" (2006), and "Cars 2" (2011).
