William Alonzo Anderson (12 September 1916 – 29 April 1981), known as Cat Anderson, was an American jazz trumpeter best known for his long period playing with Duke Ellington's orchestra, and for his extremely wide range (more than five octaves), especially his playing in the higher registers. Born in Greenville, South Carolina, Anderson lost both parents when he was four years old, and was sent to live at the Jenkins Orphanage in Charleston, where he learned to play trumpet.
