Steve Jobs ousted from Apple (1985)
After a power struggle with CEO John Sculley and the board, Apple stripped Jobs of his operational role. He resigned and founded NeXT, taking several Apple engineers with him.
Apple lost its visionary founder and floundered for a decade; Jobs built NeXT and later bought Pixar.
Apple acquired NeXT in 1997 and Jobs returned, eventually saving the company with the iMac and iPhone.
A founder removed by his own board retains enormous institutional power; the question is whether that power pulls him back in or drives a permanent split.
