Why Is Harold F. Blum Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Harold Francis Blum was a physiologist who explored the interaction of light and chemicals on cells, especially sunlight-induced skin cancer. Early life and education Harold Blum was born on February 12, 1899, in Escondido, California. For a year during the First World War, he served with the American Expeditionary Forces Signal Corps in France. Blum graduated in 1922 from the University of California, Berkeley, with an A.B. in zoology with honors. He attended Harvard Medical School from 1923 to 1924, then returned to Berkeley for a Ph.D. in physiology and graduated in 1927. During his PhD studies Blum worked for the San Francisco Bay Marine Piling Committee. Blum completed postdoctoral studies at the Laboratoire Maritime de Concarneau in France and the University of Liège in Belgium in 1933.
