Robert J. Lamphere (February 14, 1918 - January 7, 2002) was a former agent of the Federal Bureau of Investigation (FBI) involved in the cases of atomic spies Klaus Fuchs, Harry Gold, Julius Rosenberg, and Ethel Rosenberg, as well as British spy Kim Philby.

"He had a hand in every major Soviet spy case from the end of World War II through the mid-1950s.

[1][2][4][5][6][7] In September 1941, Lamphere joined the FBI and worked for half a year in Birmingham, Alabama.

"[1] Lamphere died age 83 in Tucson, Arizona, from a combination of Parkinson's disease and prostate cancer.

"[10] Historian Harvey Klehr, reviewing the book, noted Lamphere's criticism of J. Edgar Hoover: "Although Lamphere clearly admires Hoover, and praises his political acumen, it is evident that Hoover’s fondness for draconian punishments of underlings, his encouragement of excessive flattery, and his often petty demands sometimes prevented the FBI from making full use of its resources.
