Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed Satchmo, Satch, and Pops, was an American trumpeter, composer, vocalist and occasional actor who was one of the most influential figures in jazz. His career spanned five decades, from the 1920s to the 1960s, and different eras in the history of jazz. In 2017, he was inducted into the Rhythm & Blues Hall of Fame.

Armstrong was born and raised in New Orleans. Coming to prominence in the 1920s as an “inventive” trumpet and cornet player, Armstrong was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. Around 1922, he followed his mentor, Joe “King” Oliver, to Chicago to play in the Creole Jazz Band. In the Windy City, he networked with other popular jazz musicians, reconnecting with his friend, Bix Beiderbecke, and made new contacts, which included Hoagy Carmichael and Lil Hardin. He earned a reputation at “cutting contests“, and relocated to New York in order to join Fletcher Henderson‘s band.

With his instantly recognizable rich, gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also very skilled at scat singing. Armstrong is renowned for his charismatic stage presence and voice almost as much as for his trumpet playing. Armstrong’s influence extends well beyond jazz, and by the end of his career in the 1960s, he was widely regarded as a profound influence on popular music in general. Armstrong was one of the first truly popular African-American entertainers to “cross over”, that is, whose skin color became secondary to his music in an America that was extremely racially divided at the time. He rarely publicly politicized his race, often to the dismay of fellow African Americans, but took a well-publicized stand for desegregation in the Little Rock crisis. His artistry and personality allowed him access to the upper echelons of American society, then highly restricted for black men.

Armstrong often stated that he was born on July 4, 1900. Although he died in 1971, it was not until the mid-1980s that his true birth date, August 4, 1901, was discovered by Tad Jones by researching baptismal records. At least three other biographies treat the July 4th birth date as a myth. Armstrong was born in New Orleans to Mary Albert and William Armstrong. Albert was from Boutte, Louisiana, and gave birth at home when she was about sixteen. William Armstrong abandoned the family shortly after. Armstrong played in brass bands and riverboats in New Orleans, first on an excursion boat in September 1918. He traveled with the band of Fate Marable, which toured on the steamboat Sidney with the Streckfus Steamers line up and down the Mississippi River.
