The story of Louis Armstrong (Trumpet, vocalist, cornet) is the classic tale of the child who grows up in poverty, commits petty crimes and is a victim of racial segregation, only to be saved and redeemed by his talents, in this case his musical talent. So this man is born in a New Orleans slum and after being abandoned by his father and left in the care of his grandmother, he suddenly finds himself working for a family of Lithuanian Jews, the Karnofskys, who took the boy as a member of their family.

The Karnofskys were decisive in the life of little Louis. For some reason they insisted on strengthening his taste for music, keeping him away from the problems of the street. Even when Armstrong was summoned by music, the same family gave him his first trumpet. 

For Louis Armstrong, "jazz" was just a word he heard from the New Orleans brass bands. He learned to play the cornet in the reformatory, with the New Orleans Home for Colored Waifs band, and when he left there, after doing all kinds of jobs, he managed to get into cabarets in Storyville where nightclubs abounded. He then managed to meet the renowned cornetist Joe King Oliver, his instrumental master and almost father, as he later considered him.

Like many musicians, Louis Armstrong (Satchmo) migrated to Chicago to join King Oliver's Creole Jazz band and then moved to New York, where he came to the attention of Fletcher Henderson, who hired him in his orchestra. It was in New York where Louis switched to the trumpet, debuted with it at the Roseland Ballroom and revolutionized jazz with a unique and innovative style, until he achieved the prestige that accompanied him for the rest of his life.
