Mauguin originally intended to become a school teacher and enrolled at
École normale supérieure de Saint-Cloud in 1902. Later he moved to
École Normale Supérieure, Paris, where he obtained his
Doctor of Science in 1910 in the field of
organic chemistry. During his chemistry studies, he also attended lectures on mathematics offered at
Sorbonne University, including those by
Émile Picard,
Henri Poincaré,
Paul Painlevé, and
Édouard Goursat. Before
World War I, Mauguin was briefly a faculty member at
University of Bordeaux in 1912 and at
University of Nancy from 1913 to 1919. He moved back to
University of Paris in 1919 and worked under
Frédéric Wallerant as an associate professor of mineralogy. He took over the position in 1933 and became a professor of mineralogy at
University of Paris and worked until 1948, when Mauguin retired. Mauguin was the first to notice that when he sandwiched the semi-solid liquid crystals between two aligned
polarizers, he could twist them in relation to each other, but the light continued to be transmitted. This phenomenon is called
Mauguin regime (waveguide regime) in twisted nematic effect . == References ==
