Although orchestral players resented Sargent for much of his career after the 1936 interview, instrumental soloists generally liked working with him. The cellist Pierre Fournier called him a "guardian angel" and compared him favourably with George Szell and Herbert von Karajan. Artur Schnabel, Jascha Heifetz and Yehudi Menuhin thought similarly highly of him. Cyril Smith wrote in his autobiography, "...he seems to sense what the pianist wants of the music even before he begins to play it... He has an incredible speed of mind, and it has always been a great joy, as well as a rare professional experience, to work with him." For this reason, among others, Sargent was continually in demand as a conductor for concertos.
