Pops was the first superstar of jazz music.
"A jazz pioneer, Louis Armstrong was the first important soloist to emerge in jazz, and he became the most influential musician in the music's history. As a trumpet virtuoso, his playing, beginning with the 1920s studio recordings he made with his Hot Five and Hot Seven ensembles, charted a future for jazz in highly imaginative, emotionally charged improvisation. For this, he is revered by jazz fans."

As a child, Armstrong worked for and befriended Lithuanian-Jewish immigrants, the Karnofskys. He would later write that they treated him as one of their own and loaned him the money to buy his first horn. He often wore a Star of David in their honor.
