Arturo Toscanini

Arturo Toscanini, an Italian, conducted the metropolitan opera from 1908 to 1915, the New York philharmonic from 1926 to 1936, and many other orchestras worldwide.

Many critics, fellows, and much of the classical listening audience consider this greatest musician of all time. His photographic memory gave him extraordinary command over a vast repertoire of works, and allowed him to correct errors that his colleagues left unnoticed for decades. His renowned brilliant intensity, restless perfectionism, phenomenal ear for detail and sonority characterized his work.
