Chicago’s Richard Daley (1902-1976) was among the most famous big-city mayors of 20th century America. He earned election to the Illinois House of Representatives in 1936, and served as Democratic minority leader in the state senate from 1941 through 1946. Moving into Chicago politics, Daley took over as chair of the Cook County Democratic Central Committee in 1953. Elected Chicago mayor for the first of six terms in 1955, he cultivated alliances with organized labor and industry, but drew criticism for the violence that erupted at the 1968 Democratic convention. Holding office until he died from a heart attack, Daley was succeeded by his son as mayor in 1989.
