Some former notable police chiefs are Theodore Roosevelt (1858-1959), J.Edgar Hoover (1895-1972), and James Traficant (1941-2014). David Hennessy (1858-1890) is also among the top five, according to Ranker’s list.
Theodore Roosevelt is also on the list of United States presidents, and the site notes him for his leadership of the Progressive Movement, range of achievements and his exuberant personality. He was the founder of the Progressive Party of 1912 and a leader of Republican Party. J. Edgar Hoover was the first director of the Bureau of Investigation of the United States, the predecessor to the FBI. Hoover gets credit for instituting several modernizations to police technology that include forensic labor and centralizing fingerprint files, states Ranker.
James Traficant represented Ohio as a member of United States House of Representatives. He lost this position as a result of his conviction on various counts, including forcing his aides to perform chores at his Ohio farm and houseboat in Washington D.C., filing false tax returns, taking bribes and racketeering, explains Ranker.
David Hennessy was at one time a police chief of New Orleans, Louisiana. In 1820, his assassination led to a sensational trial. A mob formed outside the prison the following day after the verdict, forcing open the doors and lynching 11 of 19 Italians indicted in connection with Hennessy’s murder, says Ranker.
