Rainer Kurt Sachs

Sachs went in 1937 to the USA where he got his bachelor's degree at MIT in 1958 received his doctorate in 1953 at Syracuse University in gravitational theory with Peter Bergmann ( The structure of particles in linearized gravitational theory ). As a post - graduate student, he was 1959/60 at the University of Hamburg and 1960/61, at the University of London. In 1962, he was Assistant Professor at Stevens Institute of Technology in 1963 and an associate professor and then professor at the University of Texas. From 1969 he was professor at the University of California, Berkeley.

In 1962 he proved with Joshua Goldberg to the set of Goldberg -Sachs, which excludes the existence of geodetic and scherungsfreier null congruences on special algebraic properties of the Weyl tensor. The Ehlers- Geren -Sachs theorem in cosmology in 1968, is named P. Geren and Jürgen Ehlers for him.

Until 1985 he worked in the fields of relativistic cosmology and astrophysics. He then devoted himself to mathematical and computational biology, especially of radiation biology.
