Frederic Lewis Tuffley (23 October 1855 – 1 April 1935), better known by his stage name, Eric Lewis, was an English comedian, actor and singer. In a career spanning five decades, he starred in numerous comedies and in a few musical comedy hits, but he is probably best remembered today as the understudy to George Grossmith in the Gilbert & Sullivan comic operas of the 1880s who left the D'Oyly Carte Opera Company just in time to give Henry Lytton his big break.
