Brief scientific biography

Hans Freudenthal was born in Luckenwalde, a small town in the Prussian province of Brandenburg, between Berlin and Frankfurt/Oder, on 17 September 1905. His parents were Elisabeth Ehmann and Joseph Freudenthal. His father was the precentor and religious teacher of the small local Jewish community. In fact, the house where he was born served as the synagogue. He attended the local state school, Friedrichsschule, which evolved into a Reformrealgymnasiumand passed his Abiturthere. Although highly interested in the humanities as well as in literature, he decided to study mathematics and physics and entered Berlin university in 1923.

The mathematics professors there were Erhard Schmidt, Richard von Mises, Issai Schur, and Ludwig Bieberbach, and among the younger staff were John von Neumann, Heinz Hopf, and Karl Löwner, who introduced Freudenthal into intuitionism. A visit by Luitzen E.J. Brouwer in the winter semester 1926-27 brought him into closer contact w

History of Prof. Dr. Hans Freudenthal (1905 – 1990)

Hans Freudenthal was born in 1905 in the German town of Luckenwalde, the son of a Jewish teacher. Even at a young age he was interested in differential equations and integration, but by the age of 13 he had also read all the works of Goethe and Schiller. In 1923 he went to Berlin and Paris to study mathematics. After gaining his doctorate he moved to Amsterdam, in the Netherlands, where he became assistant to L.E.J. Brouwer, the famous mathematician, in 1930. Shortly after, he married Suus Lutter, who was a pedagogue. Thanks to his marriage to an Arian Dutch woman and a certain amount of luck, Freudenthal was able to survive the Second World War.
In 1946 Freudenthal became a professor in Utrecht, appointed to a chair in pure and applied mathematics and the principles of mathematics. In his time Freudenthal was an accomplished and well-known mathematician, and he made substantial contributions to topology, geometry and the theory of Lie groups.

As a teacher he acquired international fa
