Louis Armstrong, born in 1901 in New Orleans, Louisiana, emerged as a jazz pioneer and influential musician in the genre's history. Beginning with his 1920s studio recordings with the Hot Five and Hot Seven ensembles, Armstrong's trumpet virtuosity and emotionally charged improvisation set a new standard for jazz. His distinctively phrased baritone singing and engaging personality also made him a lasting figure in popular music, showcased in hit recordings like "Hello Dolly" and "What a Wonderful World." Armstrong's career spanned decades, earning him the nickname "Ambassador Satch" for his global recognition and cultural impact. He passed away in 1971 at the age of 69, posthumously receiving a Grammy Lifetime Achievement Award in 1972.

Armstrong's early interest in music led him to self-taught cornet playing, eventually joining prominent bands like the Kid Ory Band and the Fate Marable band. He made his recording debut as a leader in 1925 and went on to achieve chart success with hits like "West End Blues" and "Ain't Misbehavin'." Throughout the years, Armstrong toured extensively, recorded with various labels, and collaborated with artists like Ella Fitzgerald. Despite his versatility and widespread popularity, Armstrong faced criticism from jazz purists for his shift towards light entertainment. His diverse catalog of recordings remains a testament to his musical genius and enduring appeal across different audiences.
