Roy DisneyRoy Disney, the son and nephew of The Walt Disney Co. founders who twice led shareholder revolts that shook up the family business, died Wednesday. He was 79. The company announced that Disney died in Newport Beach, Calif., after a bout with stomach cancer.

Although he generally stayed out of the spotlight, Roy Disney didn't hesitate to lead a successful campaign in 1984 to oust Walt Disney's son-in-law after concluding he was leading the company in the wrong direction.

Nearly 20 years later, he launched another successful shareholders revolt, this time against Michael Eisner, the man he'd helped bring in after the previous ouster.
