Arturo Toscanini was particularly impressed by him, and he wrote in a note to Cantelli's wife Iris in 1950, after four concerts of Cantelli as guest conductor with the NBC Symphony Orchestra:
I am happy and moved to inform you of Guido's great success and that I introduced him to my orchestra, which loves him as I do. This is the first time in my long career that I have met a young man so gifted. He will go far, very far.[1]
Toscanini, who died in 1957, was never told of Cantelli's death.
Cantelli left a small but valuable legacy of recordings.
