Abraham Elieser Adolph Schönberg, known as Al Shean, was a comedian and vaudeville performer. Other sources give his birth name variously as Adolf Schönberg, Albert Schönberg, or Alfred Schönberg. He is most remembered for being half of the vaudeville team Gallagher and Shean, and as the uncle of the Marx Brothers (Leonard Joseph "Chico" Marx, Adolph (Arthur) "Harpo" Marx, Julius Henry "Groucho" Marx, Milton "Gummo" Marx and Herbert Manfred "Zeppo" Marx).
