Richard M. Daley
Richard Michael Daley (born April 24, 1942) is an American politician who served as the 54th Mayor of Chicago, Illinois from 1989 to 2011.
Daley was elected mayor in 1989 and was reelected five times until declining to run for a seventh term.
At 22 years, he was the longest-serving Chicago mayor, surpassing the tenure of his father, Richard J. Daley.
As Mayor, Daley took over the Chicago Public Schools, developed tourism, oversaw the construction of Millennium Park, increased environmental efforts and the rapid development of the city's central business district downtown and adjacent near North, near South and near West sides.
He also expanded employee benefits to same-sex partners of city workers, and advocated for gun control.
Daley received criticism when family, personal friends, and political allies disproportionately benefited from city contracting.
He took office in a city with regular annual budget surpluses and left the city with massive structural deficits.
His budgets ran up the largest deficits in Chicago history.
A national leader in privatization, he temporarily reduced budgetary shortfalls by leasing and selling public assets to private corporations, but this practice removed future sources of revenue, contributing to the city's near insolvency at the end of his tenure.
Police brutality was a recurring issue during his mayorship.
