Frans Maurits Jaeger (born May 11, 1877 in The Hague , † March 2, 1945 in Haren (Groningen) ) was a Dutch chemist .

Life

Jaeger, the son of an artillery officer and mathematics teacher, studied chemistry and geology in Leiden from 1895 with the candidate exam in 1898 and was an assistant at the Geological Museum. In 1900 he obtained his doctoral examination. He then studied crystallography in Berlin for two years. In 1903 he was in Leiden at APN Franchimont with the work en Crystallographic symmetry molekulaire van plaatsings-isomeric benzene derivatives (Crystallographic and molecular symmetry of positionally benzene derivatives) PhD . From 1902 to 1908 he was a chemistry teacher at the high school in Zaandam . In 1904 he became a private lecturer at the University of Amsterdam. In 1908 he became a lecturer and in 1909 professor for inorganic and physical chemistry at the University of Groningen , succeeding Jacob Böeseken. His inaugural address was on atomistic and energetic ideas in the evolution of general chemistry (Dutch). In 1910/11 he conducted research in the geophysics laboratory of the Carnegie Institution in Washington DC with Arthur Louis Day , where he also took inspiration for the new chemistry laboratory at the University of Groningen opened in 1912, and in 1929 he was George Fisher Baker Lecturer at Cornell University . In 1934 he was elected a corresponding member of the Göttingen Academy of Sciences . In 1943 he retired in Groningen, ostensibly for health reasons, but in reality out of dissatisfaction with the measures taken by the German occupiers.

He was very versatile, but was particularly concerned with crystallography and symmetry in chemistry (optical activity, which he measured for many complex compounds, from 1914 with X-ray crystallography, for example for ultramarine), solid-state chemistry, measurements in physical chemistry at high temperatures (up to 1600 degrees Celsius) and with the history of chemistry, for example with Cornelis Drebbel and his contemporaries and Johann Joachim Becher .

In 1904 he married Maria Antonina de Bruyn, with whom he had a son and a daughter. His hobbies were music, painting and astronomy. He was a member of the Dutch Academy of Sciences .
