Arthur Duncan
Arthur Chester Duncan was an American tap dancer, also called an "Entertainer's Entertainer," known for his stint as a performer on The Lawrence Welk Show from 1964 to 1982. This, along with his earlier inclusion on The Betty White Show in 1954 and with the help of White herself, made him the first African-American regular on a variety television program. He performed all over the world, and notably at Lincoln Center and Carnegie Hall.
