I feel that it was the greatest honor of my life when, in 1915, my distinguished friend Enrico Caruso called me to New York to be his coach and accompanist. I had previously served him in the same capacities during his frequent visits to Berlin, where our closer friendship began in the year of 1909. In those days I always eagerly awaited Caruso's arrival in Berlin, not only because it was an inspiration and a musical education to work with the great master of song, but also be cause his very presence di?'used sunshine and happiness. In fact, it is difficult for me to say whom I loved more, Caruso the artist or Caruso the man — both were so great.
