J. Edgar / J. Edgar

As head of the FBI for nearly 50 years, Edgar Hoover became one of the most powerful Americans. Having served under eight presidents and in three wars, Hoover used both a ruthless and epic method to ensure the security of his country. Projecting a cautious persona in public and private, he left few in his inner circle. Among his close friends were Clyde Tolson and Helen Gandy, his loyal secretary.
