The English conductor John Barbirolli and the Pole Artur Rodzinski, were joint replacements for Toscanini in 1936. The next year Barbirolli was made the main conductor, a post he held until the spring of 1941. In 1943, Rodzinski became conductor. He had also been conducting on the Sunday afternoon radio broadcast when CBS listeners around the country heard the announcer break in on Arthur Rubinstein's performance of Brahms's Second Piano Concerto to tell them about the attack on Pearl Harbor.
