Chesney Archives, Johns Hopkins Medicine A giant in the field of nutritional science, ELMER VERNER McCOLLUM (pictured) was credited by his peers as the greatest single contributor to the improvement of human health through nutrition. The first chairman of the School of Public Health's Biochemistry Department, Dr. McCollum was the first to use rats in nutritional experimentation. He discovered vitamin A in 1913 and co-discovered vitamin D in 1921. These findings helped him demonstrate the relationship between nutritional deficiencies and clinical symptoms of disease. As a result of his work, childhood rickets, caused by a vitamin D deficiency, quickly disappeared in America. His dedication to research and teaching was equaled by his commitment to improving public awareness of the benefits of good nutrition. He helped bring about profound changes in the American diet by contributing regular columns on nutrition to McCall's magazine between 1922 and 1946.


BURTON McCOLLUM, who created this chair to honor his brother, was a physician.


PIERRE A. COULOMBE, the E.V. McCollum Professor and Chair of Biochemistry and Molecular Biology, joined the Bloomberg School of Public Health in December 2008. He holds additional faculty appointments in the departments of biological chemistry and dermatology in the School of Medicine. Dr. Coulombe is a leading expert in the cytoskeleton and underlying causes of diseases affecting the skin. He has received numerous awards for both his teaching and research. Most recently he was awarded the William F. Montagna Award by the Society for Investigative Dermatology for his overall contributions to the understanding of keratin function, and their implication in diseases. Dr. Coulombe has authored 111 publications and is the co-inventor of the patented use of Nrf2 inducers to treat epidermolysis bullosa simplex and related diseases.
