Perhaps the Legion had a convention there.
Legionnaires' disease acquired its name in July 1976 when an outbreak of pneumonia occurred among people attending a convention of the American Legion at the Bellevue-Stratford Hotel in Philadelphia.
America had a Social Healthcare System in 1976?
Philly....another dirty city?
Lack of cleanliness knows no boundaries.
Legion members should be proud to have disease named after them.
