Weyl, ca. 1930 (Göttingen).
Courtesy of the Archives of the Mathematisches Forschungsinstitut Oberwolfach,
Weyl was born in the little town of Elmshorn (near Hamburg), Germany on
November 9, 1885. The son of Ludwig and Anna Weyl, he showed an unusual
aptitude for math and science as a youth. From 1904 to 1908 he studied
mathematics and physics in Munich and Göttingen, obtaining his PhD (at
the age of 22) in 1908 under the supervision of the great German
mathematician David Hilbert. His doctoral dissertation explored
singular integral equations with special consideration of Fourier
integral theorems. Following a teaching post in Göttingen, he
took a professorship at the Eidgenössiche Technische Hochschule (Swiss
Federal Technical University) in Zürich, Switzerland, where he was
appointed the chair of mathematics in 1913. Just 27 years old,
Weyl was now a senior colleague of Einstein who, already a professor of
physics at the school, was working feverishly on his greatest
achievement – the General Theory of Relativity.
Soon afterward, however, Pauli apologized to Weyl when he came to fully comprehend the significance of Weyl's discovery:
During his lifetime, Weyl published a large number of books and papers on space, time, matter, philosophy, logic, and the history of mathematics. His books include:
Was ist Materie? (What is Matter?), 1924
Gruppentheorie und Quantenmechanik (Group Theory and Quantum Mechanics), 1928.
Elementary Theory of Invariants, 1935
Philosophy of Mathematics and Natural Science, 1949.
Raum-Zeit-Materie (Space-Time-Matter), 1952
The Concept of a Riemannian Surface, 1955
Weyl's gauge theory of the gravitational and electromagnetic field and/or closely related mathematical material can be found in Space-Time-Matter and in
