PHYSICIAN FRIDERIK PREGL, NOBELIST OF SLOVENIAN DESCENT
Abstract
With his Nobel Prize for chemistry in 1923, Friderik (Fritz) Pregl (1869–1930), a physician and a university professor for medical chemistry became a famous person both among Slovenians and world’s most eminent scientists. He did not win the Nobel Prize only for his work on the field of microanalysis of organic substances because he would have invented something very new but because he made a significant contribution to the improvement of the methodology in the quantitative organic microanalysis of that time. In his scientific work he focused on reducing the amount of substance designed for the analysis and on the improvement of the analytical scales. He improved the scales’ accuracy to a thousandth of a gram, decreased the amount of testing substance and reduced working time and the energy spared for the work considerably. Consequently, the study of substance was possible also in cases where only 3–5mg of the substance or even less were available. The same amount of substance, which had been sufficient only for one analyse, was now enough to carry out more than 50 analyses. Therefore, his improvements made the work of physiological and pathological chemists more exact and quicker. Scientific success and many publications made Pregl’s name; he became an honorary doctor of the wellknown university in Göttingen, a member of the academy of sciences and arts in Vienna and an honorary citizen of GrazDownloads
