Pregl, Fritz(frĭts prā`gəl), 1869–1930, Austrian physiologist and chemist, M.D. Univ. of Graz, 1894. He taught at the universities of Innsbruck (1910–13) and Graz (from 1913). For his methods of quantitative organic microanalysis he received the 1923 Nobel Prize in Chemistry. His other contributions include several micromethods for measuring atomic groups and a sensitive microbalance.
Born Sept. 3, 1869, in Laibach, now Ljubljana, Yugoslavia; died Dec. 13, 1930, in Graz. Austrian chemist.
Pregl was a professor at the University of Innsbruck beginning in 1910 and at the University of Graz beginning in 1913. He founded quantitative organic microanalysis by developing methods for determining elements and functional groups in compounds analyzed in small amounts (2–6 mg) and by inventing specialized apparatus for these procedures. In particular, Pregl’s techniques facilitated the rapid development of the synthesis of hormones, vitamins, and other complex natural substances. Pregl received a Nobel Prize in 1923.
