J. Edgar Hoover.

John Edgar Hoover was the first director of the Federal Bureau of Investigation (F.B.I.) and served in that post from the time he was 29 years old until his death at the age of 77. J. Edgar Hoover began working in U.S. government service in 1913, first at the Library of Congress, then at the Justice Department. During World War I, Hoover worked for the Bureau of Investigation, keeping statistical records of immigrants for the Alien Enemy Bureau. A vigorous anti-communist, Hoover quickly moved up the agency's ranks in the postwar period, and by 1924 was appointed Director of the Bureau of Investigation (later called the Federal Bureau of Investigation). He held the post until 1972, an administration that lasted through eight presidential administrations, fromCalvin Coolidge.到理查德尼克松。在面对犯罪和政治颠覆，警惕的警惕地，呼吸悬停在极端警惕，这可能会倾向于滥用权力。在Hoover的任期期间F.B.I.在大家上，从歹徒和间谍到文化人物一样，他们留在了约翰列侬那马丁路德金。那Marilyn Monroe.和Eldridge砍刀。J.
