FBI spied on Albert Einstein for 22 years until his death
The FBI started spying on renowned German-born scientist Albert Einstein when he moved to America in 1933, shortly before Adolf Hitler rose to power. Agents listened to the physicist's phone calls and browsed his mail and trash, suspecting he was a Soviet spy. The surveillance, totalling 1,800 pages, ended with Einstein's death on April 18, 1955, with no supporting evidence.
