ANNAPOLIS, Md. — A colorful and complex figure in Maryland politics, Marvin Mandel was seen by some as an innovator who reorganized state government to be more efficient. For others, he was forever stained by his conviction for selling the powers of office.

Mandel died Sunday afternoon after spending two days with family celebrating his stepson’s 50th birthday. He was 95. The cause of death was not yet known.

He was widely acknowledged as a creative and effective governor who restructured state government and pushed big school construction and mass transit initiatives. Yet he made national headlines in a political corruption scandal that sent him to federal prison in a legal case that was later overturned.

Then, there was his tumultuous personal life — including a temporary exile from the governor’s mansion when he left his wife of 32 years to marry another woman. His first wife, Barbara “Bootsie” Mandel, wouldn’t leave the mansion.

“No other governor has had the lasting impact on all three branches of Maryland government,” Gov. Larry Hogan in a statement Sunday night.
