Revilo Pendleton Oliver (July 7, 1908 – August 20, 1994) was an American professor of Classical philology, Spanish, and Italian at the University of Illinois at Urbana-Champaign.

[3] Oliver attracted national notoriety in the 1960s when he published an article after the President John F. Kennedy assassination, alleging that Lee Harvey Oswald was part of a Soviet conspiracy against the United States.

[5][independent source needed] He later wrote that as an adolescent, he found amusement in watching evangelists "pitch the woo at the simple-minded", attending performances of Aimee Semple McPherson and Katherine Tingley.

[10] After the assassination of President John F. Kennedy, Oliver wrote a two-part article called "Marxmanship in Dallas" published in March 1964 in American Opinion, the Birch magazine.

It alleged that Lee Harvey Oswald had carried out the murder as part of a communist conspiracy to kill Kennedy, whom Oliver described as a puppet who had outlived his usefulness.

[4] In 1966, Oliver embarrassed Welch by proclaiming that the world's troubles would be ended if "all Jews were vaporized at dawn tomorrow" along with "Illuminati" and "Bolsheviks".

[2] Oliver is described as "a virulent anti-Semite" in Claire Conner's memoir about the time, Wrapped in the Flag: A Personal History of America's Radical Right.

[3] Oliver is probably the author of the 1959 anonymous novel The John Franklin Letters, which was cited by Pierce as his most direct inspiration for The Turner Diaries.

[3] "Oliver's writings on Jews and race-mixing became an important part of neo-Nazi culture in the early twenty-first century," according to Andrew S. Winston of the University of Guelph.

[22] Damon T. Berry, in his book Blood and Faith: Christianity and American White Nationalism (Syracuse University Press, 2017), devotes a chapter to Oliver, concluding that "Oliver hated both conservativism and Christianity ... because they equally represented to him an ideological poison that was alien to the best instincts of the white race to defend its existence.

His estate arranged to publish several works posthumously through Historical Review Press and Liberty Bell, as well as to attend to the needs of his wife Grace in her declining years.

[23] He used the pen names "Ralph Perier" (for The Jews Love Christianity and Religion and Race) and "Paul Knutson" (for Aryan Asses).
