Albert Szent-Györgyi, Hungarian-American physiologist and biochemist, Nobel Prize laureate (born 1893)

Albert Imre Szent-Györgyi de Nagyrápolt was a Hungarian biochemist who won the Nobel Prize in Physiology or Medicine in 1937. He is credited with first isolating vitamin C and discovering many of the components and reactions of the citric acid cycle and the molecular basis of muscle contraction. He was also active in the Hungarian Resistance during World War II, and entered Hungarian politics after the war.

The Nobel Prize in Physiology or Medicine is awarded yearly by the Nobel Assembly at the Karolinska Institute for outstanding discoveries in physiology or medicine. The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel's 1895 will, are awarded "to those who, during the preceding year, have conferred the greatest benefit to humankind". Nobel Prizes are awarded in the fields of Physics, Medicine or Physiology, Chemistry, Literature, and Peace.

October 22 is the 295th day of the year in the Gregorian calendar; 70 days remain until the end of the year.
