His early education culminated in a Bachelor of Arts in Sociology from Knox College in Galesburg, Illinois, in 1966.

### Career
Hanssen joined the FBI in 1976 as a special agent. Initially assigned to the FBI Laboratory, he later transitioned into roles involving counterintelligence and internal security. By 1978, he had begun offering classified information to the Soviet Union through intermediaries. From 1979 onward, he operated as a mole, selling sensitive U.S. intelligence to Soviet and later Russian handlers. His access allowed him to compromise thousands of pages of classified material, including information on U.S. intelligence operations, sources, and technological capabilities.

Hanssen used dead drops and encrypted communications to pass information. He was methodical, often demanding payment in cash or diamonds and taking extensive precautions to avoid detection. His espionage activities continued through multiple presidential administrations and geopolitical shifts, ending only when the FBI finally identified him in 2001 using surveillance and physical evidence.

### Arrest and Legal Proceedings

His actions compromised national security, endangered foreign agents, and exposed systemic weaknesses in FBI counterintelligence. The case prompted major reforms, including enhanced background checks, stricter access controls, and improved internal monitoring systems. It also led to increased awareness of insider threats and the need for continuous vigilance within intelligence communities.
