American composer. He studied musicology under J. K. Paine at Harvard University. He began his compositional activities in earnest relatively late, in the 1910s. Prior to that, he had been involved in the business world. After graduating from university in 1897, he studied composition under Elgar and others. His distinctive style is characterized by a unique transformation of Impressionism, objectively expressing 20th-century America. His representative works include the orchestral suite The Adventures of a Baby Carriage (1915), and the ballets Crazy Cats (1921) and Skyscrapers (1926).

Among his works that include piano in their instrumentation, he composed not only pieces for solo piano but also a piano quintet.
