This Passing Parade entry tells the story of Dr. Joseph Goldberger (1874-1929), a Hungarian immigrant who devoted his life to finding the cause of pellagra, a disease that killed hundreds of thousands in the southern United States. Although the medical community believed that the condition was caused by a virus, Goldberger proved that a healthy diet was the cure.
