Denham Harman, M.D., Ph.D.

He gained international acclaim as the father of the free-radical theory of aging. He also discovered the role of antioxidants (vitamins C, E, and beta-carotene) in fighting heart disease and cancer. And today, the internist, chemist and octogenarian Dr. Denham Harman continues his pioneering work, searching for ways to extend a person’s healthy life span.

“He deserves the Nobel Prize,” said Dr. Donald Ingram, acting chief of the laboratory of experimental gerontology at the National Institute on Aging in Baltimore.
