On the Google home page, a pair of oranges find a place of pride in commemoration of the 118th birthday of Albert Szent-Györgyi, the Nobel Prize-winning Hungarian physiologist.

Szent-Györgyi is credited with discovering vitamin C and also the components and reactions of the citric acid cycle for which he was honored with the Nobel Prize in Physiology or Medicine in 1937. He worked in a number of universities during his research career.

The Nobel citation hailed his discoveries in connection with the biological combustion process with special reference to vitamin C and the catalysis of fumaric acid.

After World War II, Szent-Györgyi was well-recognized as a public figure and there was some speculation that he might become president of Hungary, should the Soviets permit it. Szent-Györgyi established a laboratory at the University of Budapest and became head of the biochemistry department there. He was elected to Parliament and helped re-establish the Academy of Sciences. But unhappy with the Communist takeover of Hungary, he emigrated to the United States in 1947.
He died in Woods Hole, Mass. on Oct. 22, 1986.

Vitamin C, his discovery, is essential to a healthy diet in humans, as well as being a highly effective antioxidant, acting to lessen oxidative stress. While plants are generally a good source of vitamin C, the amount in foods of plant origin depends on the precise variety of the plant, soil condition, climate where it grew, length of time since it was picked, storage conditions and method of preparation.

The Google logo in honour of Albert von Szent-Györgyi de Nagyrápol looks rich in vitamin C, as it contains oranges, lemons, strawberries and more.

Having put out commemorative doodles on events ranging from news events, civic milestones, birthdays, death anniversaries and important dates in history, Google doodles have been gaining immense popularity over the past few years

Google estimates it has created more than 900 doodles since 1998, with 270 of them running in 2010 and more than 150 in 2011.
