How would people describe Armstrong's public persona

Louis Armstrong is rightly celebrated as a master jazz trumpeter, but his distinctive gravelly-voiced singing also had a huge influence on later artists. His vocal improvisations and the powerful feeling of swing that he brought to everything he sang loosened up the more formal style of his contemporaries. Louis Armstrong was the most important and influential musician in jazz history. Although he is often thought of by the general public as a lovable, clowning personality, a gravel-voiced singer who played simple but dramatic trumpet in a New Orleans-styled Dixieland setting, Armstrong himself was so much more.
