# Walther Mayer Information

*https://en.wikipedia.org/wiki/Walther_Mayer*

**Walther Mayer** (11 March 1887 – 10 September 1948) was an Austrian mathematician, born in
Graz,
Austria-Hungary.^{
[1]} With
Leopold Vietoris he is the namesake of the
Mayer–Vietoris sequence in
topology.^{
[2]} He served as an assistant to
Albert Einstein,^{
[1]} and was nicknamed "Einstein's calculator".^{
[3]}

## Biography

Mayer studied at the
Federal Institute of Technology in
Zürich and the
University of Paris before receiving his doctorate in 1912 from the
University of Vienna;^{
[1]}^{
[4]} his thesis concerned the
Fredholm integral equation.^{
[5]}^{
[6]} He served in the military between 1914 and 1919, during which he found time to complete a
habilitation on
differential geometry.^{
[5]} Because he was Jewish, he had little opportunity for an academic career in Austria, and left the country; however, in 1926, with help from Einstein, he returned to a position at the
University of Vienna as Privatdozent (lecturer).^{
[7]} He made a name for himself in
topology with the
Mayer–Vietoris sequence,^{
[2]} and with an axiomatic treatment of
homology predating the
Eilenberg–Steenrod axioms.^{
[8]} He also published a book on
Riemannian geometry in 1930, the second volume of a textbook on differential geometry that had been started by
Adalbert Duschek with a volume on curves and surfaces.^{
[5]}

In 1929, on the recommendation of
Richard von Mises, he became Albert Einstein's assistant with the explicit understanding that he work with him on
distant parallelism, and from 1931 to 1936, he collaborated with
Albert Einstein on the
theory of relativity.^{
[1]} In 1933, after
Hitler's assumption of power, he followed Einstein to the United States and became an associate in mathematics at the
Institute for Advanced Study in
Princeton, New Jersey.^{
[1]} He continued working on mathematics at the Institute, and died in Princeton in 1948.^{
