Hoover Takes FBI Helm: Five Decades of Power

J. Edgar Hoover was 29 years old when Attorney General Harlan Fiske Stone appointed him director of the Bureau of Investigation on May 10, 1924. He would hold the position for 48 years, serving under eight presidents, transforming a corrupt and ineffective agency into the most powerful domestic law enforcement organization in the world, and wielding secret files against political enemies with an impunity that no other unelected official in American history has matched. Hoover inherited an agency in crisis. The Bureau of Investigation under his predecessor, William Burns, had been used as a political weapon during the Palmer Raids of 1919-20, conducting mass arrests of suspected radicals with no regard for civil liberties. Burns was forced out after the Teapot Dome scandal revealed corruption throughout the Justice Department. Stone gave Hoover the job with explicit instructions to professionalize the bureau and remove it from politics. Hoover fulfilled the first mandate brilliantly. He imposed strict hiring standards, requiring agents to hold law or accounting degrees. He centralized fingerprint records, created a national crime laboratory, and established the FBI National Academy to train local police. The bureau's pursuit of Depression-era outlaws like John Dillinger, Pretty Boy Floyd, and Machine Gun Kelly turned Hoover into a national celebrity and the FBI into a symbol of incorruptible federal authority. The second mandate, to stay out of politics, Hoover violated comprehensively. He compiled secret dossiers on politicians, journalists, activists, and anyone he considered a threat to national security or his own position. His COINTELPRO operations infiltrated and disrupted civil rights organizations, antiwar groups, and the Communist Party through surveillance, disinformation, and provocation. He bugged Martin Luther King Jr.'s hotel rooms and sent an anonymous letter suggesting King should commit suicide. No president dared fire him. The files were too dangerous, and Hoover's public reputation too strong. He died in office on May 2, 1972, and Congress subsequently passed legislation limiting FBI directors to a single ten-year term. The agency Hoover built remains one of his legacies; the surveillance state he pioneered is the other.
