Ernst D. Hellinger (1883-1950) Papers 1906-1975

http://findingaids.library.northwestern.edu/catalog/inu-ead-nua-archon-547

Hellinger studied integral equations, infinite systems of equations, real functions, and continued fractions. A type of integral he introduced in his dissertation became known as “the Hellinger integral” and the Hilbert-Hellinger theory of forms in infinitely many variables profoundly influenced mathematical analysis. The Ernst D. Hellinger Papers fill one and one-half boxes and are arranged in two categories: teaching files and publications. These are preceded by one folder of biographical materials.

Ernst Hellinger was born in Striegau, Silesia, on September 30, 1883. After studying at the University of Heidelberg and the University of Breslau, Hellinger took his PhD in mathematics at the University of Gottingen (where he worked with David Hilbert and Franz Klein) in 1907. Hellinger studied integral equations, infinite systems of equations, real functions, and continued fractions. Hellinger taught at Gottingen (1907-1909), Marburg (1909-1914), and Frankfurt (1914-19...

Mathematics at Northwestern University has been taught since the University itself first offered classes. One of the University's three original faculty members appointed in 1854 was Henry S. Noyes, professor of mathematics. Noyes held major responsibility for mathematics instruction at Northwestern until 1871 when Julius F. Kellogg took over the department chairmanship. Kellogg held this position until his death in 1894. During the University's early years, the mathematics curricul...
