When the National Constitution Center opened on Independence Mall in 2000, John R. FitzPatrick's daughter saw an opportunity for her history-buff father.
"This is for you," she recalls telling him.
"I'm going to work there," her father responded.
He became a tour guide at the center shortly after it opened, and he brought history alive for visitors with his booming voice and dramatic presentations.
His loud enthusiasm once disturbed a woman who was taking a tour through the center. "She complained that he was too loud," said his daughter, Sheila Taney. "When someone told him about it, he said, 'Tell her to move.' "
