William Rock

William Baker Rock (August 5, 1872 – June 27, 1922) was an American vaudeville comedian and dancer. His early career was in musical comedy, before he teamed up with Maude Fulton in the vaudeville act of Rock and Fulton. He is credited with being the first vaudeville performer to have a band accompanying his act on stage, and also one of the first to condense a Broadway musical into a vaudeville act. He later married Gladys Tilbury of Brighton, England. On July 6, 1921, he married Helen Eby of Altoona, Pennsylvania, who appeared with him in Hitchy-Koo.

On July 13, 1921, he was hospitalized and had one-third of his stomach removed. He died on June 27, 1922, at the National Stomach Hospital in Philadelphia, Pennsylvania, of cancer of the stomach. He was buried in Fairview Cemetery in Bowling Green, Kentucky.
