Source-derived summary

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. He won the Nobel Prize in Chemistry in 1923 for making important contributions to quantitative organic microanalysis, one of which was the improvement of the combustion train technique for elemental analysis.

Biography

Pregl was born in Ljubljana within Austria-Hungary to a Slovene-speaking father and German-speaking mother. He was baptized Friedrich Michael Raimund Pregl. He died in Graz, Austria in 1930.

Pregl started his career as chemist after he studied medicine at the University of Graz. 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. He invited chemists to learn his method of elemental analysis, so that the method was soon widely accepted.

Editorial summary

The public source identifies “Fritz Pregl” as slovene-Austrian Nobel prize laureate and scientist (1869-1930). This brief keeps that definition visible, then builds a research path around Fritz, Pregl and Slovene-Austrian.

Editorial reviewA productive starting point for separating a subject’s documented career from later reputation and commemoration. The current lead gives the account dated anchors—1869, 1930, 1923—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Fritz, Pregl and Slovene-Austrian providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Fritz Pregl”, the useful work is to connect “slovene-Austrian Nobel prize laureate and scientist (1869-1930)” to the records capable of establishing context and consequence.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q78482. The first chronological checks are 1869, 1930 and 1923.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
