As it happened, Szeged is the center of the paprika (red pepper) industry. Paprika was not available at Cambridge. I once saw it on the market but the vendor cautioned me that it was poisonous. One night [at Szeged] we had fresh red pepper for supper. I did not feel like eating it and thought of a way out. Suddenly it occurred to me that this was practically the only plant I had never tested. I took it to the laboratory and about midnight I knew that it was a treasure chest of vitamin C, containing 2 mg per gram. A few weeks later I had kilograms of crystalline vitamin C which I distributed all over the world among researchers who wanted to work on it. This made complete analysis and synthesis possible: Albert Szent-Györgyi, "Lost in the Twentieth Century" in Annual Review of Biochemistry vol. 32 (1963) pp. 1-14
