Abstract

Albert (von) Szent-Györgyi started his studies on biological oxidation processes - which also resulted in the discovery of vitamin C, for which he received the Nobel Price in 1937 - in the Laboratory of Physiology of the University in Groningen in 1922-1926. These studies were later continued in Cambridge (UK) and Szeged (Hungary). When he had already received the invitation as well as the financial means to come and work in Cambridge, he still did experiments in Groningen to find out whether the adrenal extract, isolated by him and later found to be a major source of vitamin C, contained the hormone essential for the survival of cats whose adrenals were removed. He was rather upset by the negative results of this experiment, judging by the recollections of a former student of his. This history constitutes an interesting example of the difference between serendipitous discovery and planned invention.
