Louis Armstrong, affectionately known as "Satchmo," was born on August 4, 1901, and remains one of the most influential figures in jazz and American music as a whole. Armstrong's innovative trumpet playing, distinctive voice, and charismatic stage presence helped shape the sound of jazz and brought it to mainstream audiences around the world. His hits like “What a Wonderful World” and “La Vie En Rose” continue to be beloved classics. Armstrong’s influence extended beyond music; he became a symbol of Black excellence and resilience during a time of significant racial inequality in the United States.
