Vitamin C is one of the first vitamins that was ever discovered and could already appear at the beginning of the 20th century. At that time, Albert Szent-Györgyi isolated the vitamin from cabbage and paprika.
Subsequently, in 1933, Walter Norman Haworth succeeded in breaking down the chemical structure of vitamin C. As a result, both received a Nobel Prize in chemistry and medicine in 1937.
The knowledge on which this was based later led to a further development that enabled the industrial production of vitamin C from simple glucose. That innovation came from Tadeus Reichstein, a chemist who was also honored with a Nobel Prize.
