Robert Hanssen

American double agent and spy (1944–2023)

Robert Philip Hanssen (April 18, 1944 – June 5, 2023) was an American Federal Bureau of Investigation (FBI) agent who spied for Soviet and Russian intelligence services intermittently against the United States from 1979 to 2001. His espionage was described by the United States Department of Justice as "possibly the worst intelligence disaster in U.S. history". In 1979, three years after joining the FBI, Hanssen approached the Soviet Main Intelligence Directorate (GRU) to offer his services, beginning his first espionage cycle, lasting until 1981.
