ABSTRACT
I had not been back for almost twenty years when I visited Vienna in 1955 to give one or two lectures. And even earlier, before I last stopped over in 1937 en route from England to America, I had been in Vienna only infrequently. I had left as soon as I finished the Gymnasium, in 1927, not quite eighteen, and returned later only to spend Christmases with my parents, rarely for more than a week at a time.
