Charles Glen King

Charles Glen King (October 22, 1896 – January 23, 1988) was an American biochemist who was a pioneer in the field of nutrition research and who isolated vitamin C at the same time as Albert Szent-Györgyi.

[3] World War I interrupted his college studies, where he served in the 12th Infantry Regiment, a heavy machine gun company.

King's contribution to the science of nutrition revolves around his isolation of vitamin C in 1931-1932 by studying the antiscorbic activities of guinea pigs with preparations from lemon juice.

Albert Szent-Györgyi was conducting similar research at the University of Szeged in Hungary, focusing on hexuronic acid.

Szent-Györgyi would later win a Nobel Prize for his part in the discovery, and controversy remains over whether both men deserve equal credit.

He also helped create the Food Protection Committee, the Recommended Dietary Allowances, the Protein Advisory Group, and the International Union of Nutritional Sciences.
