(Auto-generated)

He had been born in New Orleans and had been a quite young man there during the time that Louis Armstrong, a boy, was running errands for the dives and honky-tonks of what was always presented to me as one of the most wicked of cities—to this day, whenever I think of New Orleans, I also helplessly think of Sodom and Gomorrah.†

My father never mentioned Louis Armstrong, except to forbid us to play his records; but there was a picture of him on our wall for a long time.†

Definitions:

(1) (Louis Armstrong)
American jazz trumpeter, bandleader, and singer who helped make jazz popular around the world (1900-1971)

Raised in New Orleans, Armstrong became famous for bold trumpet solos and inventive improvisation. He also sang with a distinctive gravelly voice and helped popularize scat singing (improvised syllables instead of lyrics). Nicknamed "Satchmo," he recorded influential early jazz with small groups and later had major popular hits, including "What a Wonderful World."
