Initially Fritz Pregl's (1869-1930) scientific work had been mainly in the fields of physiology and physiological chemistry; later he turned to the study of the constitution of chemical compounds, in particular the investigation of bile acids. By 1912 he was able, by using his own methods of quantitative micro-analysis, to make measurements of carbon, hydrogen, nitrogen, sulphur, and halogen, using only 5-13 mg of starting materials with results as accurate as those obtained by macro-analysis. Later he perfected his techniques so that as little as 3-5 mg were adequate. Pregl also contributed a number of micromethods for measuring atomic groups and developed a series of apparatus, including a sensitive microbalance, necessary for his work. Recognition for his work was first accorded with the Lieben Prize for Chemistry from the Imperial Academy of Science in Vienna (1914), an honorary doctorate in philosophy from the University of Göttingen (1920 ); in 1921 he was elected Corresponding Member by the Academy of Sciences in Vienna. The greatest and most unexpected honour was the award of the Nobel Prize for Chemistry by the Swedish Academy of Sciences in 1923. O. Hammarsten, the Chairman of the Nobel Committee at the time, pointed out that it was not for a discovery, but for modifying and improving existing methods that Pregl was awarded the prize. Pregl had, in the early stages of his investigations, avoided publishing individual reports on his experiments, until he had convinced himself that his methods did not only work in his own, but also in other laboratories. He then, in 1917, set down his findings in a monograph entitled Die quantitative Microanlalyse (published by J. Springer, Berlin). A second edition was published in 1923 and a third revised and enlarged edition (256 pages) appeared in 1930. Later editions were revised by Dr. H. Roth. The seventh edition was published in 1958 by Springer in Vienna. Pregl's monograph has also been translated into French and English. Following the award of the Nobel Prize for Chemistry in 1923, chemists from all over the world came to the Medico-Chemical Institute in Graz to study Pregl's techniques of quantitative organic micro-analysis under his guidance. -cf.From Nobel Lectures, Chemistry 1922-1941.

Dezember 1930 in Graz) war ein slowenisch-österreichischer Physiologe und Chemiker. 1923 erhielt er den Nobelpreis für Chemie. Pregl war für die weitere Entwicklung der klinisch-chemischen Analytik von ausschlaggebender Bedeutung. Erst durch seine Untersuchungen wurde es grundsätzlich möglich auch in kleinsten Probenmengen, wie sie in der Regel für klinisch-chemische Untersuchungen zur Verfügung stehen, exakte Analysen durchzuführen. Pregls Arbeiten führten zu einem nachhaltigen Fortschritt in der Stoffwechsel-, Hormon- und Enzymforschung. Sprache: Deutsch Gewicht in Gramm: 550.
