Saul David Alinsky (January 30, 1909 – June 12, 1972) was an American community organizer and writer. He is generally considered to be the founder of modern community organizing, and has been compared to Thomas Paine as being "one of the great American leaders of the nonsocialist left." He is often noted for his book Rules for Radicals.

In the course of nearly four decades of political organizing, Alinsky received much criticism, but also gained praise from many public figures. His organizing skills were focused on improving the living conditions of poor communities across North America. In the 1950s, he began turning his attention to improving conditions of the African-American ghettos, beginning with Chicago's and later traveling to other ghettos in California, Michigan, New York City, and a dozen other "trouble spots".

His ideas were later adapted by some U.S. college students and other young organizers in the late 1960s and formed part of their strategies for organizing on campus and beyond.Time magazine once wrote that "American democracy is being altered by Alinsky's ideas," and conservative author William F. Buckley said he was "very close to being an organizational genius."

Saul (Hebrew: שָׁאוּל, Šāʼûl ; "asked for, prayed for"; Arabic: طالوت‎, Ṭālūt; Greek: Σαούλ Saoul; Latin: Saul) (circa 1079 BC – 1007 BC) was the first king of the united Kingdom of Israel. He was anointed by the prophet Samuel and reigned from Gibeah. He fell on his sword to avoid capture in the battle against the Philistines at Mount Gilboa, during which three of his sons were also killed. The succession to his throne was contested by Ish-bosheth, his only surviving son, and his son-in-law David, who eventually prevailed. The main account of Saul's life and reign is found in the Books of Samuel.

According to the Tanakh, Saul was the son of Kish, of the family of the Matrites, and a member of the tribe of Benjamin, one of the twelve Tribes of Israel. (1 Samuel 9:1-2; 10:21; 14:51; Acts 13:21) It appears that he came from Gibeah.

Saul married Ahinoam, daughter of Ahimaaz. They had four sons and two daughters. The sons were Jonathan, Abinadab, Malchishua and Ish-bosheth. Their daughters were named Merab and Michal.

William Frank Buckley, Jr. (November 24, 1925 – February 27, 2008) was an American conservative author and commentator. He founded the political magazine National Review in 1955, which had a major impact in stimulating the conservative movement. He hosted 1,429 episodes of the television show Firing Line from 1966 until 1999, where his public persona was famous for a sesquipedalian vocabulary. He also wrote a nationally syndicated newspaper column, and wrote numerous spy novels.

George H. Nash, a historian of the modern American conservative movement, states that Buckley was "arguably the most important public intellectual in the United States in the past half century... For an entire generation, he was the preeminent voice of American conservatism and its first great ecumenical figure." Buckley's primary contribution to politics was a fusion of traditional American political conservatism with laissez-faire economic theory and anti-communism, laying groundwork for the new American conservatism of U.S. presidential candidate Barry Goldwater and President Ronald Reagan.

Louis "Studs" Terkel (May 16, 1912 – October 31, 2008) was an American author, historian, actor, and broadcaster. He received the Pulitzer Prize for General Non-Fiction in 1985 for The Good War, and is best remembered for his oral histories of common Americans, and for hosting a long-running radio show in Chicago.

Terkel was born to Samuel Terkel, a Russian Jewish tailor and his wife, Anna Finkelin in New York City, New York. At the age of eight he moved with his family to Chicago, Illinois, where he spent most of his life. He had two brothers, Ben (1907–1965) and Meyer (1905–1958).

From 1926 to 1936, his parents ran a rooming house that also served as a meeting place for people from all walks of life. Terkel credited his understanding of humanity and social interaction to the tenants and visitors who gathered in the lobby there, and the people who congregated in nearby Bughouse Square. By 1939, he had grown to adulthood, marrying Ida Goldberg (1912–1999) that year, and the couple produced one son, Dan. Although he received his law degree from the University of Chicago Law School in 1934, he decided instead of practicing law, he wanted to be a concierge at a hotel, and he soon joined a theater group.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
