Walter Saxer

Walter Saxer (born December 2, 1896 in Stein , †  June 25, 1974 in Samaden ) was a Swiss mathematician . After Saxer had attended the canton school in Trogen , he studied at the ETH Zurich . In 1920 he received his diploma as a subject teacher and in 1923 he did his doctorate with George Pólya . He then worked first at the Federal Insurance Office, then as a main teacher at the Aarau Cantonal School. In the academic year 1926/27 he was able to deepen his knowledge thanks to a Rockefeller scholarship to the universities in Paris and Göttingen . From 1927 to 1966 he was a professor of mathematics at the ETH. In the Auditorium Maximum he lectured basic mathematical lectures for all future engineers, mathematicians and physicists. In the post-war years, the Swiss Federal Council appointed him mathematical advisor on social security issues. In this role he played a key role in the creation of the Swiss old-age and survivors' insurance (AHV).

In 1934/35 he was president of the Swiss Mathematical Society and from 1939 the youngest elected rector of the ETH.

Saxer's main area of ​​work was initially function theory . His dissertation, which deals with Picard's exceptional values ​​of the derivatives of whole functions , also contains a presentation of the Wiman-Valiron theory . In further work he examined normal families of meromorphic functions . Later he turned mainly to probability and statistics . His two-volume textbook on actuarial mathematics became a standard work.

Heinz Huber , Albert Pfluger and Heinz Rutishauser are among his students .
