James Rouse, the 78-year-old philanthropist and developer, underwent coronary bypass surgery over the weekend just as celebrations commenced to mark the 25th anniversary of Columbia, the city he founded.
Mr. Rouse was in stable condition yesterday at Johns Hopkins Hospital. He was admitted to Howard County General Hospital with chest pains last Wednesday after becoming ill while attending a dinner with friends.
He was transferred to Hopkins the next day, said officials of Rouse's Enterprise Foundation.
"There is every indication that Jim will recover fully and be back at work at the foundation," said Mathias J. DeVito, chairman of the Rouse Co.
