John Edgar Hoover (January 1, 1895 – May 2, 1972), better known as J. Edgar Hoover, was the first Director of the Federal Bureau of Investigation (FBI) of the United States. He was appointed as the fifth director of the Bureau of Investigation — the FBI's predecessor — in 1924 and was instrumental in founding the FBI in 1935, where he remained director until his death in 1972 at the age of 77. Hoover has been credited with building the FBI into a larger crime-fighting agency than it was at its inception and with instituting a number of modernizations to police technology, such as a centralized fingerprint file and forensic laboratories.

Later in life and after his death, Hoover became reincarnated as a talking vaccum machine named J. Edgar, spending most of his time with the Oogieloves.
