Albert Szent-Györgyi, a Hungarian biochemist, discovered vitamin C and rutin (vitamin P). The role of these vitamins in the body and their application to dermatology is vast. For the discovery of vitamin C and the description of oxidation, Albert Szent-Györgyi received a Nobel Prize in medicine in 1937. He discovered the role of adenosine triphosphate, actin-myosin, and many phases of the Krebs cycle, and also initiated studies on the influence of free radicals in the formation of tumors. Between 1918 and 1946, he worked in many European research centers and between 1947 and 1986, in the United States. His achievements were made possible due to his perseverance, which allowed him to overcome many maelstroms that plagued his scientific career.
