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. After World War II, he published in the National Review, becoming known as a polemicist for white supremacist and right-wing causes.
Oliver also briefly attracted national notoriety in the 1960s when he published an article after the President John F. Kennedy assassination, suggesting that Lee Harvey Oswald was part of a Soviet conspiracy against the United States. He was called to testify before the Warren Commission investigating the murder.
Revilo Pendleton Oliver was born in 1908 near Corpus Christi, Texas. He attended two years of high school in Illinois. Disliking the severe winters, and once requiring hospitalization "for one of the first mastoidectomies performed as more than a daring experiment", he relocated to California, where he studied Sanskrit. He used Max Müller's handbooks and Monier Williams' grammar, later finding a Hindu missionary to tutor him.
