Louis Armstrong (August 4, 1901 – July 6, 1971)
Armstrong was called The Father of Jazz who replaced the
Beatles on the Billboard Hot 100 chart with "Hello, Dolly!"
when he was 63 years old, the oldest person at that time
to hit the #1 ranking. As the grandson of slaves, he worked
as a paperboy and sold food he salvaged to restaurants.
Bunk Johnson, considered one of the best trumpeters of the
early 1900s, taught Louis Armstrong how to play by ear at
the age eleven when he had dropped out of school.
