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 from 1953, until his death. He has been called "the last of the big city bosses" who controlled and mobilized American cities. He was the patriarch of a powerful Chicago political family. His son, Richard M. Daley, would also go on to serve as mayor of Chicago and another son, William M. Daley, served as the United States Secretary of Commerce and White House Chief of Staff.
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 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. He has been ranked by some historians as among the ten best mayors in American history.
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 held in his city. During his tenure, 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.
