Arthur Hartmann

Arthur Martinus Hartmann (né Arthur Hartman; July 23, 1881 – March 30, 1956) was an American violinist, composer and friend of Claude Debussy.

Hartmann was the son of Sigmund Hartman and Pepi Schweiger, who had immigrated from Hungary in December 1879. His father discovered his musical talents early on, and from the age of 6 Arthur studied with the Dutch-born violinist and composer Martinus van Gelder [nl; ru] (1854–1941). Later, Hartmann would adopt "Martinus" as a middle name in his teacher's honor.

Uncle to writer/artist Alfred Bendiner (1899–1964)
