Richard J. Daley, American lawyer and politician, 48th Mayor of Chicago (d. 1976)
Richard Joseph Daley (May 15, 1902 – December 20, 1976) was an American politician who served as the Mayor of Chicago from 1955 and the chairman of the Cook County Democratic Party Central Committee from 1953 until his death. He has been called "the last of the big city bosses" who controlled and mobilized American cities. Daley was Chicago's third consecutive mayor from the working-class, heavily Irish-American South Side neighborhood of Bridgeport, where he lived his entire life. He was the patriarch of the Daley family, whose members include Richard M. Daley, another former mayor of Chicago; William M. Daley, a former United States Secretary of Commerce; John P. Daley, a member of the Cook County Board of Commissioners; and Patrick Daley Thompson, an alderman of the Chicago City Council.

Daley is remembered for doing much to save Chicago from the declines that other rust belt cities such as Cleveland, Buffalo, and Detroit experienced during the same period. He had a strong base of support in Chicago's Irish Catholic community and was treated by national politicians such as Lyndon B. Johnson as a pre-eminent Irish-American, with special connections to the Kennedy family. Daley played a major role in the history of the Democratic Party, especially with his support of John F. Kennedy in the presidential election of 1960 and of Hubert Humphrey in the presidential election of 1968. He would be the longest-serving mayor in Chicago history until his record was broken by his son Richard M. Daley in 2011.

On the other hand, Daley's legacy is complicated by criticisms of his response to the Chicago riots that followed the assassination of Martin Luther King Jr. and his handling of the notorious 1968 Democratic National Convention that happened in his city. He also had enemies within the Democratic Party. In addition, many members of Daley's administration were charged and convicted for corruption, although Daley himself was never charged with any crime.
