Career
Mahler was a student at the universities in Frankfurt and Göttingen, graduating with a Ph.D. from Johann Wolfgang Goethe University of Frankfurt am Main in 1927; his advisor was Carl Ludwig Siegel.[2] He left Germany with the rise of Adolf Hitler and accepted an invitation by Louis Mordell to go to Manchester. However, at the start of World War II he was interned as an enemy alien in Central Camp in Douglas, Isle of Man, where he met Kurt Hirsch, although he was released after only three months.[3] He became a British citizen in 1946.
Mahler held the following positions:
- University of Groningen
- Assistant 1934-36
- University of Manchester
- Assistant Lecturer at 1937–39, 1941–44
- Lecturer, 1944–47; Senior Lecturer, 1948–49; Reader, 1949–52
- Professor of Mathematical Analysis, 1952–63
- Professor of Mathematics, Institute of Advanced Studies, Australian National University, 1963–68 and 1972–5
- Professor of Mathematics, Ohio State University, USA, 1968–72
- Professor Emeritus, Australian National University, from 1975.
Research
Mahler worked in a broad variety of mathematical disciplines, including transcendental number theory, diophantine approximation, p-adic analysis, and the geometry of numbers.[1]
Mahler proved that the Prouhet–Thue–Morse constant and the Champernowne constant 0.1234567891011121314151617181920... are transcendental numbers.[4][5]
Awards
He was elected a member of the Royal Society in 1948[1] and a member of the Australian Academy of Science in 1965. He was awarded the London Mathematical Society's Senior Berwick Prize in 1950, the De Morgan Medal, 1971, and the Thomas Ranken Lyle Medal, 1977.
Personal life
Mahler spoke fluent Japanese and was an expert photographer.
