In 1926, Oskar Klein gave Kaluza's classical five-dimensional theory a quantum interpretation, to accord with the then-recent discoveries of Heisenberg and Schrödinger. Klein introduced the hypothesis that the fifth dimension was curled up and microscopic, to explain the cylinder condition.
German mathematician Theodor Kaluza and Swedish physicist Oskar Klein independently developed the Kaluza–Klein theory in 1921, which used the fifth dimension to unify gravity with electromagnetic force.
It was a result coming out of his unification of electromagnetism and gravitation based on Einstein's general theory of relativity in a five-dimensional spacetime. This idea had previously been explored by Kaluza, but Klein made it more acceptable by suggesting that the extra dimension could be compactified and therefore remain unobservable ...

Klein assumed the fifth dimension to be periodic with a period l = ℏ c 2 k e l = \hbar c \Large\frac{\sqrt {2k}} {e} l = ℏ c e 2 k where e e e was the charge of the electron and k k k was Einstein's constant of gravitation. The dimension was on the order of the Planck length.
16. Sept. 2013 · Oskar Klein and the fifth dimension. Finn Ravndal. After a short biographical summary of the scientific life of Oskar Klein, a more detailed and hopefully didactic presentation of his derivation of the relativistic Klein-Gordon wave equation is given.
