DETROIT (AP) — General Motors Co. says former Chairman and CEO Robert Stempel has died.
The automaker announced Stempel's death in a statement Monday.
The Detroit News and the Detroit Free Press report he was 77 and died Saturday in Florida.
Stempel led the company from 1990-92 until he was forced out in a boardroom coup.
Detroit-based GM says Stempel "admirably led the company during very difficult times in the early 1990s."
Stempel spent three decades at GM, including work as an engineer. The automaker credits him with leading the development of the catalytic converter, which it calls "one of the great environmental advancements in auto history."
