Arthur Fiedler (December 17, 1894 – July 10, 1979) was the long-time conductor of the Boston Pops Orchestra, a symphony orchestra that specializes in popular and light classical music. With a combination of musicianship and showmanship, he made the Pops one of the best-known orchestras in the country. Some criticized him for watering down music, particularly when adapting popular songs or edited portions of the classical repertoire, but Fiedler deliberately kept performances informal, light, and often self-mocking to attract more listeners.

Fiedler was born in Boston, Massachusetts. His father was an Austrian-born violinist who played in the Boston Symphony Orchestra, and his mother was a pianist and musician. He grew up in Boston, and attended Boston Latin School until his father retired and returned to Austria, where he studied and worked until returning to Boston at the start of World War I.

In 1909, his father took him to Berlin to study violin with Willy Hess, and then in 1915 he joined the Boston Symphony Orchestra under Karl Muck as a violinist. He also worked as a pianist, organist, and percussionist.
