Otto Ernst Heinrich Klemperer (1899–1987[1]) was a physicist expert in electron optics.
He was granted his doctorate by the Humboldt-Universität zu Berlin in 1923.
[5] During the 1930s, he worked at the Cavendish Laboratory at the University of Cambridge on discrepancies between Fermi's theory of β-decay and the observed radiation properties of rubidium and polonium.
[3] He was later an assistant professor and Reader in Physics at Imperial College, London,[6] where he wrote the third edition of his book on electron optics with Mike Barnett.
[7] The conductor Otto Klemperer was his father's cousin.
