Richard Joseph Daley (May 15, 1902 – December 20, 1976) served for 21 years as the mayor and undisputed Democratic boss of Chicago and is considered by historians to be the "last of the big city bosses." He played a major role in the history of the Democratic Party, especially with his support of John F. Kennedy in 1960 and of Hubert Humphrey in 1968.

Daley was Chicago's third mayor in a row from the working-class, heavily Irish American Bridgeport neighborhood on Chicago's South Side, where he lived his entire life.

Daley had two bases of power, serving as a Committeeman and Chairman of the Cook County Democratic Central Committee from 1953, and as mayor of Chicago from 1955. He used both positions until his death in 1976 to dominate party and civic affairs. Daley's Democratic political machine was often accused of corruption, but while many of Daley's subordinates were jailed, Daley was never formally charged with corruption.

He is remembered for doing much to avoid the declines that some other "rust belt" cities like Cleveland, Buffalo and Detroit experienced during the same period. He had a strong base of support in Chicago's Irish Catholic community, and he was treated by national politicians such as Lyndon B. Johnson as a preeminent Irish American, with special connections to the Kennedy family.

Malcolm X ( /ˈmælkəm ˈɛks/; May 19, 1925 – February 21, 1965), born Malcolm Little and also known as El-Hajj Malik El-Shabazz (Arabic: الحاجّ مالك الشباز‎), was an African-American Muslim minister and human rights activist. To his admirers, he was a courageous advocate for the rights of African Americans, a man who indicted white America in the harshest terms for its crimes against black Americans. Detractors accused him of preaching racism, black supremacy, antisemitism, and violence. He has been called one of the greatest and most influential African Americans in history.

Malcolm X's father died—killed by white supremacists, it was rumored—when he was young, and at least one of his uncles was lynched. When he was thirteen, his mother was placed in a mental hospital, and he was placed in a series of foster homes. In 1946, at age 20, he went to prison for breaking and entering.

In prison, Malcolm X became a member of the Nation of Islam and after his parole in 1952 he quickly rose to become one of its leaders. For a dozen years Malcolm X was the public face of the controversial group, but disillusionment with Nation of Islam head Elijah Muhammad led him to leave the Nation in March 1964. After a period of travel in Africa and the Middle East, he returned to the United States, where he founded Muslim Mosque, Inc. and the Organization of Afro-American Unity. In February 1965, less than a year after leaving the Nation of Islam, he was assassinated by three members of the group.

Leon Mathis Despres (February 2, 1908 - May 6, 2009) was an American author, attorney and politician. He was best known as a long-time alderman in Chicago, where he regularly disagreed with then-mayor Richard J. Daley, often engaging in loud arguments and debates on the assembly floor.

A native of Chicago, Despres received his undergraduate and law degrees in 1927 and 1929, respectively, from the University of Chicago, where he was elected to Phi Beta Kappa, before beginning a legal practice.

In April 1955, Despres was elected to the Chicago City Council from the city's Hyde Park neighborhood, as alderman of the 5th ward. Serving until 1975, Despres gained fame as an independent Democrat, consistently opposing the policies of Chicago Mayor Richard J. Daley. Frequently on the short end of 49-1 votes, Despres became known as the "liberal conscience of Chicago." Because of his strong advocacy of civil rights and open housing, Despres also became known as "the lone negro on the City Council," even though he was white and the council had six black alderman allied with the mayor.
