Edward Harrigan (October 26, 1844 – June 6, 1911), sometimes called Ned Harrigan, was an Irish-American actor, singer, dancer, playwright, lyricist and theater producer who, together with Tony Hart (as Harrigan & Hart), formed one of the most celebrated theatrical partnerships of the 19th century. His career began in minstrelsy and variety but progressed to the production of multi-act plays full of singing, dancing and physical comedy, making Harrigan one of the founding fathers of modern American musical theatre.
