Louis Armstrong in Paris by photographer Ervin Marton (with Pearl Bailey?).
From Wikipedia:
He worked for a Lithuanian-Jewish immigrant family, the Karnofskys, who had a junk hauling business and gave him odd jobs. They took him in and treated him as almost a family member, knowing he lived without a father, and would feed and nurture him. He later wrote a memoir of his relationship with the Karnofskys titled, Louis Armstrong + the Jewish Family in New Orleans, La., the Year of 1907. In it he describes his discovery that this family was also subject to discrimination by “other white folks’ nationalities who felt that they were better than the Jewish race. I was only seven years old but I could easily see the ungodly treatment that the White Folks were handing the poor Jewish family whom I worked for.” Armstrong wore a Star of David pendant for the rest of his life and wrote about what he learned from them: “how to live—real life and determination.” The influence of Karnofsky is remembered in New Orleans by the Karnofsky Project, a non-profit organization dedicated to accepting donated musical instruments to “put them into the hands of an eager child who could not otherwise take part in a wonderful learning experience.”
