Felix Michael Haurowitz (March 1, 1896, Prague – December 2, 1987, Bloomington, Indiana) was a Czech-American physician and biochemist.
He visited Leonor Michaelis's laboratory in Berlin, where he learned physicochemical methods, such as pH measurement, from the biochemist Peter Rona (1871–1945).
In 1925 Haurowitz was appointed a docent in Prague and this gave him the financial security to marry Regina "Gina" Hedvika Perutz (1903–1983) in June 1925.
[1] On a visit to Felix and Gina Haurowitz, Perutz became interested in the problem of determining the chemical structure of hemoglobin.
Landsteiner's techniques were developed by Haurowitz for "quantitative determination of the composition of the antigen-antibody precipitate, calculation of dissociation constants, and other parameters of the antibody-antigen interaction.
"[1] In the 1930s and early 1940s, Felix Haurowitz and Friedrich Breinl (1888–1936), as well as other scientists including Jerome Alexander, Stuart Mudd, William Whiteman Carlton Topley, and, most notably, Linus Pauling, proposed variants of the now-discredited template theory of antibody formation.
[5][6][7] In 1938 Haurowitz was working at Copenhagen's Carlsberg Laboratory at the invitation of the Danish biochemist Albert Fischer, when the Munich Agreement was made.
However, Felix Haurowitz spent two more years at Istanbul University o fulfill his academic contract, but he did visit his family in 1947.
