McCarthyism, name given to the period of time in American history that saw Wisconsin Sen. Joseph McCarthy produce a series of investigations and hearings during the 1950s in an effort to expose supposed communist infiltration of various areas of the U.S. government. The term has since become a byname for defamation of character or reputation by means of widely publicized indiscriminateallegations, especially on the basis of unsubstantiated charges.

McCarthy was elected to the Senatein 1946 and rose to prominence in 1950 when he claimed in a speech that 205 communists had infiltrated the State Department. McCarthy’s subsequent search for communists in the Central Intelligence Agency, the State Department, and elsewhere made him an incredibly polarizing figure. After McCarthy’s reelection in 1952, he obtained the chairmanship of the Committee on Government Operations of the Senate and of its Permanent Subcommittee on Investigations.
For the next two years he was constantly in the spotlight, investigating various government departments and questioning innumerable witnesses about their suspected communist affiliations. Although he failed to make a plausible case against anyone, his colourful and cleverly presented accusations drove some persons out of their jobs and brought popular condemnation to others.
McCarthyism both reached its peak and began its decline during the “McCarthy hearings”: 36 days of televised investigative hearings led by McCarthy in 1954. After first calling hearings to investigate possible espionage at the Army Signal Corps Engineering Laboratories in Fort Monmouth, New Jersey, the junior senator turned his communist-chasing committee’s attention to an altogether different matter, the question of whether the Army had promoted a dentist who had refused to answer questions for the Loyalty Security Screening Board.
The hearings reached their climax when McCarthy suggested that the Army’s lawyer, Joseph Welch, had employed a man who at one time had belonged to a communist front group. Welch’s rebuke to the senator—“Have you no sense of decency, sir, at long last? Have you left no sense of decency?”—discredited McCarthy and helped to turn the tide of public opinion against him.
Moreover, McCarthy was also eventually undermined significantly by the incisive and skillful criticism of a journalist, Edward R. Murrow. Murrow’s devastating television editorial about McCarthy, carried out on his show, See It Now, cemented him as the premier journalist of the time. McCarthy was censured for his conduct by the Senate, and in 1957 he died. While McCarthyism proper ended with the Senator’s downfall, the term still has currency in modern political discourse.
