Felix Bloch (diplomatic officer)

Felix Bloch (born July 19, 1935) is a former director of European and Canadian Affairs in the United States Department of State. He is known for his connection to the Robert Hanssen espionage case.

Hanssen, a Federal Bureau of Investigation (FBI) agent who was a spy for the Soviet Union and later Russia, reported to his KGB handlers about ongoing FBI investigations of Bloch and Reino Gikman in order to save them from possible arrest. Gikman escaped to Moscow and made a warning phone call to Bloch only later.^{: 246–247} The FBI intercepted this and other espionage-related phone calls, but was unable to collect enough evidence to charge Bloch with any crime. Bloch worked a total of 32 years at the State Department.
