Born in the Back o' Town neighborhood of New Orleans on August 4, 1901, Louis Daniel Armstrong grew up in poverty but found music early. Sent to the Colored Waifs' Home at age 12, he received his first formal instruction on the cornet there. Under the mentorship of King Oliver, he developed with extraordinary speed into one of the most gifted improvisers who ever lived.
Armstrong moved to Chicago in 1922 to join Oliver's Creole Jazz Band, and his star rose quickly. His Hot Five and Hot Seven recordings of the mid-1920s are among the most significant in the history of American music, establishing the language of jazz soloing that all players since have worked within or against.
