Louis Armstrong

Louis Daniel Armstrong (August 4, 1901{{ref|birthday}} – July 6, 1971) (also known by the nicknames Satchmo and Pops) was an American jazz musician. Probably the most famous jazz musician of the 20th century, Armstrong was a charismatic, innovative performer whose musical skills and bright personality transformed jazz from a rough regional dance music into a popular art form. Armstrong first achieved fame as a trumpeter, but was also one of the most influential jazz singers, and towards the end of his career was best known as a vocalist.

Notes

• {{note|birthday}}Armstrong said he was not sure exactly when he was born, but celebrated his birthday on July 4. He usually gave the year as 1900 when speaking in public (although he used 1901 on his Social Security and other papers filed with the government). Using Roman Catholic Church documents from when his grandmother took him to be baptised, New Orleans music researcher Tad Jones established his birthday was August 4, 1901. With various other collaborative evidence, this date is now accepted by Armstrong scholars.
