4. Steve Jobs
Apple's creator and founder was also the father of PIXAR. Jobs took it upon himself to finance the formation of PIXAR as they broke away in 1986, investing nearly $50 million of his own dollars when all was said and done. When sold to Disney in May of 2006, Jobs became a major shareholder in Disney with a 7% share and also a seat on the board of directors, as well as a 50.1% share in PIXAR stock. Jobs was also responsible for moving the PIXAR films to the now-normal summer release slate, and freeing them from the usual pre-Christmas release window of November.
