Arturo Toscanini (; Italian: [arˈtuːro toskaˈniːni]; March 25, 1867 – January 16, 1957) was an Italian conductor. He was one of the most acclaimed and influential musicians of the late 19th and early 20th century, renowned for his intensity, his perfectionism, his ear for orchestral detail and sonority, and his eidetic memory. He was at various times the music director of La Scala in Milan and the New York Philharmonic. Later in his career he was appointed the first music director of the NBC Symphony Orchestra (1937–54), and this led to his becoming a household name (especially in the United States) through his radio and television broadcasts and many recordings of the operatic and symphonic repertoire.
