Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed "Satchmo", "Satch", and "Pops", was an American jazz and blues trumpeter and vocalist. He was among the most influential figures in jazz. His career spanned five decades and several eras in the history of jazz. Armstrong received numerous accolades including the Grammy Award for Best Male Vocal Performance for Hello, Dolly! in 1965, as well as a posthumous win for the Grammy Lifetime Achievement Award in 1972. His influence crossed musical genres, with inductions into the DownBeat Jazz Hall of Fame, the Rock and Roll Hall of Fame, and the National Rhythm & Blues Hall of Fame, among others.
Armstrong was born and raised in New Orleans. Coming to prominence in the 1920s as an inventive trumpet and cornet player, he was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. Around 1922, Armstrong followed his mentor, Joe "King" Oliver, to Chicago to play in Oliver's Creole Jazz Band. Armstrong earned a reputation at "cutting contests", and his fame reached band leader Fletcher Henderson.
