Biomedical Research

Through brilliant field investigations of orphanages, insane asylums, and prison farms in the South during the 1910s and early 1920s, Joseph Goldberger (1874-1929) demonstrated that pellagra, which killed thousands of mostly poor people yearly, was caused by a nutritional deficiency resulting from an unbalanced diet and could be cured by the addition of fresh milk, meat, or yeast. The deficient nutrient was identified in 1937 as niacin, a member of the vitamin B complex.
