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.
Stephen Rosenbaum
Rosenbaum began his career in visual effects at the reconstructed Computer Graphics Department of Lucasfilm's effects division Industrial Light & Magic in 1989. The previous members of this department moved to the building next door and formed the company Pixar. This new group of artists received their first chance to make a computer generated character when James Cameron asked them to create the Pseudopod water creature for "The Abyss". Cameron followed with Terminator 2 and the group expanded the artist base and created one of the first digital manipulations of a human character. The artists continued to thrive with opportunities to animate and render the seminal dinosaurs in "Jurassic Park". Rosenbaum then oversaw the removal of Lt. Dan's legs, rephrasing the words of presidents, and the fanciful feather animation in "Forrest Gump". These movies help spark the rapid transition of traditional film-processed visual effects and inspired a complete paradigm shift in visual effects and filmmaking methodologies and commercial digital imagery manipulation.
