Bruno Walter
Among the guest conductors he played under were Bruno Walter, Wilhelm Furtwängler, Richard Strauss, Victor de Sabata, Fritz Reiner, Pierre Monteux, Igor Stravinsky, and Otto Klemperer. His first public performance was the First Symphony of Brahms under Walter. Giulini told interviewers that he detested the dictatorial, often demeaning manner of Molinari, the orchestra's music director, but loved the gentle manner of Bruno Walter, who he said had a gift for making every musician feel important.
