Louis Armstrong (August 4, 1901 – July 6, 1971) was an American trumpeter and vocalist. He was among the most influential figures in jazz, with a career spanning 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 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. This photograph, taken in 1947 by Harry Warnecke and Gus Schoenbaechler, shows Armstrong playing the trumpet in a blue suit against a yellow background. The image is in the collection of the National Portrait Gallery.
