British arrest of physicist Klaus Fuchs for atomic espionage

British authorities arrested Klaus Fuchs on suspicion of passing atomic secrets to the Soviet Union; he later confessed to espionage.

Fuchs's arrest confirmed serious penetration of Allied nuclear research, intensified U.S.-U.K. security cooperation and contributed to expanded anti-espionage efforts during Truman's administration.
