Jonathan Pollard

Jonathan Jay Pollard is a former American intelligence analyst who was jailed for spying for Israel. In 1984, Pollard sold numerous state secrets, including the National Security Agency's ten-volume manual on how the U.S. gathers its signal intelligence, and disclosed the names of thousands of people who had cooperated with U.S. intelligence agencies. He was apprehended in 1985, and in subsequent proceedings agreed to a plea deal, pleaded guilty to spying for and providing top-secret classified information to Israel. (Wikipedia)
