Klein was born in Danderyd outside Stockholm, son of the chief rabbi of Stockholm, Gottlieb Klein from Humenné
in Slovakia
and Antonie (Toni) Levy. He became a student of Svante Arrhenius

broke out and he was drafted into the military. From 1917, he worked a few years with Niels Bohr

in the University of Copenhagen and received his doctoral degree at the University College of Stockholm
(now Stockholm
University) in 1921. In 1923, he received a professorship at University of Michigan

in Ann Arbor and moved there with his recently wedded wife, Gerda Koch from Denmark. Klein returned to Copenhagen in 1925, spent some time with Paul Ehrenfest

in 1926 and in 1930 accepted the offer of the professorial chair in physics at the Stockholm
University College, which had previously been held by Erik Ivar Fredholm

until his death in 1927. Klein was awarded the Max Planck Medal in 1959. He retired as professor emeritus in 1962. Klein is credited for inventing the idea, part of Kaluza–Klein theory, that extra dimensions may be physically real but curled up and very small, an idea essential to string theory / M-theory. In 1938, he proposed a boson-exchange model for charge-charging weak interactions (radioactive decay), a few years after a similar proposal by Hideki Yukawa. His model was based on a local isotropic gauge symmetry and anticipated the later successful theory of Yang-Mills. The Oskar Klein
