Chattanooga is the fourth-largest city in the US state of Tennessee, with a population of 167,674 as of the 2010 census. It is the seat of Hamilton County. Located in southeastern Tennessee on Chickamauga Lake and Nickajack Lake, which are both part of the Tennessee River, Chattanooga lies approximately 120 miles (190 km) to the northwest of Atlanta, Georgia, 120 miles (190 km) to the southwest of Knoxville, about 135 miles (217 km) to the southeast of Nashville, and about 148 miles (238 km) to the northeast of Birmingham, Alabama. Chattanooga abuts the Georgia border, and the region is at the junction of three major interstate highways: I-24, I-75, and I-59.

The city, which has a downtown elevation of approximately 680 feet (210 m), lies at the transition between the ridge-and-valley portion of the Appalachian Mountains and the Cumberland Plateau. The city is therefore surrounded by various mountains and ridges. The official nickname for Chattanooga is the Scenic City.

Chattanooga is ranked 8th out of America's 100 largest metro areas for the best "Bang For Your Buck" city, according to Forbes magazine. The study measured overall affordability, housing rates, and more. Since 1990, Chattanooga has been recognized as a Tree City USA community.

Alton Glenn Miller (March 1, 1904 – missing in action December 15, 1944) was an American jazz musician (trombone), arranger, composer, and bandleader in the swing era. He was one of the best-selling recording artists from 1939 to 1943, leading one of the best known Big Bands. Miller's notable recordings include "In the Mood", "Moonlight Serenade", "Pennsylvania 6-5000", "Chattanooga Choo Choo", "A String of Pearls", "At Last", "(I've Got a Gal In) Kalamazoo", "American Patrol", "Tuxedo Junction", and "Little Brown Jug". While he was traveling to entertain U.S. troops in France during World War II, Glenn Miller disappeared in bad weather over the English Channel. The Glenn Miller Orchestra was re-formed after the war and continues to record and perform to this day.

Miller was born on a farm in Clarinda, Iowa, to Lewis Elmer Miller and Mattie Lou (née Cavender). He went to grade school in North Platte in western Nebraska. In 1915, Miller's family moved to Grant City, Missouri. Around this time, Miller had finally made enough money from milking cows to buy his first trombone and played in the town orchestra. In 1918, the Miller family moved again, this time to Fort Morgan, Colorado, where Miller went to high school. During his senior year, Miller became very interested in a new style of music called "dance band music." He was so taken with it that he formed his own band with some classmates. By the time Miller graduated from high school in 1921, he had decided he wanted to become a professional musician.

The Andrews Sisters were a highly successful close harmony singing group of the swing and boogie-woogie eras. The group consisted of three sisters: contralto LaVerne Sophia Andrews (July 6, 1911 – May 8, 1967; Age 55), soprano Maxene Angelyn Andrews (January 3, 1916 – October 21, 1995; Age 79), and mezzo-soprano Patricia Marie "Patty" Andrews (born February 16, 1918; Age 94). Throughout their long career, the sisters sold well over 75 million records (the last official count released by MCA Records in the mid-1970s). Their 1941 hit "Boogie Woogie Bugle Boy" can be considered an early example of rhythm and blues or jump blues.

The Andrews Sisters' harmonies and songs are still influential today, and have been covered by entertainers such as Bette Midler, the Puppini Sisters and Christina Aguilera. The group was inducted into the Vocal Group Hall of Fame in 1998.

The Andrews sisters were born in Minnesota to a Greek immigrant father and a Norwegian American mother, Olga "Ollie" (née Sollie) Andrews (1886–1948) and Peter Andreas (proper probable Greek form of name Petros Andreou), who took the name of Andrews (1884–1949).

Charles Morrison Robinson (March 3, 1867 – August 20, 1932), most commonly known as Charles M. Robinson, was an American architect. He worked in Altoona and Pittsburgh, Pennsylvania from 1889 to 1906 and in Richmond, Virginia from 1906 until the time of his death in 1932. He is most remembered as a prolific designer of educational buildings in Virginia, including public schools in Richmond and throughout Virginia, and university buildings for James Madison University, College of William and Mary, Radford University, Virginia State University, and the University of Richmond. He was also the public school architect of the Richmond Public Schools from 1910 to 1929. Many of his works have been listed on the National Register of Historic Places.

Robinson was born in Hamilton, Virginia in Loudoun County, Virginia, the son of architect James T. Robinson. He apprenticed with D.S. Hopkins, of Grand Rapids, Michigan, and John K. Peebles of Richmond, Virginia. In 1889, Robinson formed the architectural firm of Smith & Robinson with G. T. Smith in Altoona, Pennsylvania. In 1891, Robinson married Altoona native, Annie Custer. They had two children, Charles Custer Robinson (born 1893) and Miriam Robinson (born September 1895). At the time of the 1900 United States Census, Robinson was living at 1910 West Chestnut Avenue in Altoona. He had two live-in servants, Bridget Sheehan and Mattie Jones, at that time. In 1901, Robinson moved his architectural practice from Altoona to Pittsburg, Pennsylvania.

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.
