John Sculley
From Mac Guides
John Sculley was the third and longest serving CEO of Apple, from April 1983 to June 1993. He succeeded Mike Markkula and was replaced by Michael Spindler.
Sculley was lured to join Apple by Steve Jobs after his job as a president of Pepsi. Ironically, it was also Sculley who pushed Jobs out of Apple in 1985. His tenure is regarded by many as unsuccessful, beginning the company's decline that was only reversed by Jobs when he returned to the company many years later.
