Vitamin C

In 1932, Professor C. Glen King of the University of Pittsburgh isolated vitamin C, a medical and scientific breakthrough, after five years of effort. By painstaking research extracting components from lemon juice - requiring untold thousands of lemons - King and his colleagues isolated a crystalline substance, identified, and later synthesized vitamin C. Their discovery meant prevention of the disease of scurvy, long a source of human suffering. During WW II, King was named chairman of the Nutrition Foundation, which funded research into the nutritional problems facing a country and an army at war. He continued his innovative work with vitamin C until his retirement from Columbia University in 1964.
