In 1879, he conducted the first American production of a Savoy opera, H.M.S. Pinafore and became associated with Gilbert and Sullivan works for the next decade. He also conducted a number of other musical theatre works and at music halls. In 1913 and 1914, he composed musical scores for silent films, including In the Land of the Head Hunters.
