On this date in 1955, Richard J. Daley secured the Democratic nomination to run for mayor of Chicago. He had defeated Martin Kennelly, a Democrat who had been mayor of Chicago since 1947, by more than 100,000 votes. UIC Special Collections and University Archives holds the papers of both Richard J. Daley and Martin Kennelly. See the finding aids (inventory listings) for Kennelly and for Daley, and make an appointment to look at the collections in person in our reading room.
