In the early 20th century, Bronzeville was known as the "Black Metropolis," one of the nation's most significant landmarks of African-American urban history. Between 1910 and 1920, during the peak of the "Great Migration," the population of the area increased dramatically when thousands of African-Americans fled the oppression of the south and emigrated to Chicago in search of industrial jobs. Many famous people were associated with the development of the area including: Andrew "Rube" Foster, founder of the Negro National Baseball League; Ida B. Wells, a civil rights activist, journalist and organizer of the NAACP; Margaret Taylor-Burroughs, noted artist, author, and one of the co-founders of the DuSable Museum of African American History; Bessie Coleman, the first African-American woman pilot; Gwendolyn Brooks, famous author and first African-American recipient of the Pulitzer Prize, actress Marla Gibbs, the legendary singers, Sam Cooke and Lou Rawls, and Louis Armstrong, the legendary trumpet player and bandleader who performed at many of the area's night clubs. The neighborhood contains the Chicago Landmark Black Metropolis-Bronzeville District.
