Arthur Fiedler (December 17, 1894 – July 10, 1979) was an American conductor known for his association with both the Boston Symphony and Boston Pops orchestras. With a combination of musicianship and showmanship, he made the Boston Pops one of the best-known orchestras in the United States. Fiedler was sometimes criticized for over-popularizing music, particularly when adapting popular songs or editing portions of the classical repertoire, but he kept performances informal and sometimes self-mocking to attract a bigger audience.
