Boris Yuzhin

Boris Nikolaevich Yuzhin (; born February 21, 1942 ) is a former Soviet spy. He was a mole in the KGB, spying for the Federal Bureau of Investigation in the 1970s and 1980s before being caught and imprisoned. Arriving in San Francisco in 1975, he, as an expert in semiconductors, posed as a visiting scientist at UC Berkeley where he attempted to find any useful information or possible contacts. (A group "North" unit usually consisted of one or two officers of the PR (political intelligence) and KR (foreign counterintelligence) lines, as well as one from the X line (scientific and technical intelligence).) Occasionally, officers from group "North" would visit a residency to liaison with the work of the "main enemy groups". Group "North" was in the First Division of the PGU and was headed by Vadim Kirpichenko , who was the former KGB rezident for Tunisia and Egypt in Cairo (1970-1974) that allegedly recruited Nasser's intelligence chief Sami Sharaf.

Yuzhin worked at the Soviet Consulate General in San Francisco, California, where he revealed that Harry Bridges was a KGB agent and that Bridges told the KGB in 1980 that Ronald Reagan would be more predictable and that the KGB should support Reagan during the 1980 election rather than Carter whom the KGB abhorred. David Wise stated that 36 agents were lost because of Ames. Yuzhin spent six years of a 15-year sentence in Perm 35 (ITK VS-389/35), a Siberian prison.
