Gerald Rudolph Ford Jr. (born Leslie Lynch King Jr.; July 14, 1913 – December 26, 2006) was an American politician who served as the 38th President of the United States from August 1974 to January 1977, following the resignation of Richard Nixon.
 Prior to this he served eight months as the 40th Vice President of the United States, following the resignation of Spiro Agnew.
 He was the first person appointed to the vice presidency under the terms of the 25th Amendment, and consequently the only person to have served as both Vice President and President of the United States without being elected to executive office.
 Before his appointment to the vice presidency, Ford served 25 years as U.S. Representative from Michigan's 5th congressional district, the final nine of them as the House Minority Leader.
Abraham Lincoln ( ; February 12, 1809 – April 15, 1865) was an American politician and lawyer who served as the 16th President of the United States from March 1861 until his assassination in April 1865.
 Lincoln led the United States through its Civil War—its bloodiest war and perhaps its greatest moral, constitutional, and political crisis.
 In doing so, he preserved the Union, paved the way to the abolition of slavery, strengthened the federal government, and modernized the economy.
Tremont House (1850–1871, pictured left) was a leading hotel in Chicago, United States, that served as the Headquarters for the Illinois Republican Party during the 1860 Republican National Convention held at the nearby Wigwam as they lobbied for Abraham Lincoln's nomination.
 Both Lincoln and Stephen Douglas started their Senatorial campaigns from the balcony of this hotel.
 It was the third hotel bearing this name constructed at the Southeast corner of Lake Street and Dearborn in Chicago.
 It was a 260-room hotel by early Chicago architect John M. Van Osdel, who is known as the architect of the Illinois Executive Mansion.
 It was a block masonry structure with the finest amenities of the day.
 The original Tremont House built in 1833 had been named after the Boston Tremont House.
 In 1861, this building served as Douglas' deathplace.
Stephen Arnold Douglas (April 23, 1813 – June 3, 1861) was an American politician from Illinois and the designer of the Kansas–Nebraska Act.
 He was a member of the House of Representatives, the United States Senate, and the Democratic Party nominee for president in the 1860 election, losing to Republican Abraham Lincoln.
 Douglas had previously defeated Lincoln in a Senate contest, noted for the famous Lincoln–Douglas debates of 1858.
 He was nicknamed the "Little Giant" because he was short in physical stature, but a forceful and dominant figure in politics.
 (His height is given in various sources as being in the range of 5 ft to 5 ft ; five feet four is reported most often.)
Lyndon Baines Johnson ( ; August 27, 1908January 22, 1973), often referred to as LBJ, was an American politician who served as the 36th President of the United States from 1963 to 1969, assuming the office after serving as the 37th Vice President of the United States from 1961 to 1963.
 A Democrat from Texas, he also served as a United States Representative and as the Majority Leader in the United States Senate.
 Johnson is one of only four people who have served in all four federal elected positions.
The Lincoln–Douglas debates (also known as The Great Debates of 1858) were a series of seven debates between Abraham Lincoln, the Republican candidate for the United States Senate from Illinois, and incumbent Senator Stephen Douglas, the Democratic Party candidate.
 At the time, U.S. senators were elected by state legislatures; thus Lincoln and Douglas were trying for their respective parties to win control of the Illinois General Assembly.
 The debates previewed the issues that Lincoln would face in the aftermath of his victory in the 1860 presidential election.
 Although Illinois was a free state, the main issue discussed in all seven debates was slavery in the United States.
Alton is a city on the Mississippi River in Madison County, Illinois, United States, about 15 mi north of St. Louis, Missouri.
 The population was 27,865 at the 2010 census.
 It is a part of the Metro-East region of the Greater St. Louis metropolitan area.
 It is famous for its limestone bluffs along the river north of the city, for its role preceding and during the American Civil War, and as the hometown of jazz musician Miles Davis and Robert Wadlow, the tallest known person in history.
 It was the site of the last Abraham Lincoln and Stephen Douglas debate in October 1858.
 The former state penitentiary here was used during the war to hold up to 12,000 Confederate prisoners of war.
Stephen John Brademas Jr. (March 2, 1927 – July 11, 2016) was an American politician and educator originally from Indiana.
 He served as Majority Whip of the United States House of Representatives for the Democratic Party from 1977 to 1981 at the conclusion of a twenty-year career as a member of the United States House of Representatives.
 In addition to his major legislative accomplishments, including much federal legislation pertaining to schools, arts, and the humanities, he served as the 13th president of New York University from 1981 to 1992, and was a member of and subsequently the chairman of the board of the Federal Reserve Bank of New York.
 In addition he was a board member of the New York Stock Exchange and the Rockefeller Foundation.
James Alexander McDougall (November 19, 1817 – September 3, 1867) was an American attorney and politician elected to statewide office in two U.S. states, then to the United States House of Representatives and United States Senate.
 A gifted orator, McDougall began his career as a civil engineer in New York, then read law, rising quickly to heights in his profession in Illinois, where he became a friend of fellow prairie attorneys Abraham Lincoln, Edward D. Baker, and Stephen Douglas.
 Like many Americans, McDougall was drawn to Gold Rush California in 1849; he resumed his law practice and was elected second attorney general for the new state of California.
 In the election of 1860, Lincoln won the presidency as a Republican, Baker was elected Republican senator from Oregon, and McDougall was elected senator from California, joining Douglas in the Senate as fellow War Democrats.
 All three of McDougall's Prairie State friends would die in the six years before his term as senator expired.
 A noted drinker, McDougall once gave an address to the Senate disparaging a proposed rule to outlaw the sale of alcohol in the United States Capitol, but died shortly after leaving the Senate, "...hastened by his indulgence in the bowl."
