Louis Armstrong (1901-1971) was a renowned American jazz musician, virtuosic trumpet player, and influential cultural figure. He was one of the first African-American entertainers to successfully cross the colour line of racially segregated America, his charisma and talent earning affection throughout the country and internationally. Armstrong's impact on jazz and popular music was tremendous. In the words of Bing Crosby, "He is the beginning and the end of music in America."
