A deadly Purple Plague was killing untold numbers of people in Metropolis, and threatening to spread to the whole world. Professor Henry Travers was desperately working on developing a cure. An eminent scientist named Dr. Greenley led the committee observing the first public test of Travers' proposed cure. Unfortunately, the serum failed to cure a victim dying from the Purple Plague. Professor Travers was driven from the failed demonstration by a chorus of boos.
Later Superman found Travers despondent after he had received a dishonorary dismissal from his scientific society. It was Dr. Greenley who spearheaded the dismissal of Travers. Superman had to work hard to rally Travers back to his work on coming up with a cure for the plague.
Tragedy befell Dr. Greenley's own family when his only son fell ill with the plague. The boy, who appeared to be four years old, was near death. Travers by then felt that he had discovered the error in his past formula and that his new version was successful. Superman rushed Dr. Greenley's son to Travers to test the serum. It worked and the boy recovered.
A grateful Dr. Greenley told Professor Travers, "I'll have you reinstated in the Society at once -- and your serum made available to all doctors! You're a great man, Travers -- a great man!!"
