Died: 13 December 1930, Graz, Austria

Prize motivation: “for his invention of the method of micro-analysis of organic substances”

Prize share: 1/1


In nature organisms are composed of an enormously varied quantity of chemical compounds, with the element carbon as a common component. Determining the composition of these chemical compounds is a matter of great importance within chemistry. During the 1910s Fritz Pregl developed methods for doing this. Through an ingenious apparatus and methodology, he made it possible to precisely determine the composition of much smaller amounts of a substance than had been possible before. This was especially important in physiological contexts.
