Who was Fritz Pregl?

Fritz Pregl (Slovene: Friderik Pregl; 3 September 1869 – 13 December 1930), was a Slovenian-Austrian chemist and physician from a mixed Slovene-German-speaking background. Pregl was born in Ljubljana within Austria-Hungary to a Slovene-speaking father and German-speaking mother. Pregl started his career as chemist after he studied medicine at the University of Graz. He was baptized Friedrich Michael Raimund Pregl. With his focus on physiology and especially chemical physiology, he suffered from the limitations of quantitative organic microanalysis. The small quantities of substances he obtained during the research of bile acid made it necessary to improve the process of elemental analysis by reducing the necessary components. At the end of his research, he had lowered the minimal amount of substance necessary for the analysis process by a factor of 50. Fritz Pregl, was a Slovenian-Austrian chemist and physician from a mixed Slovene-German-speaking background.
