In the autumn of 1896, Alys and I went to America for three months,...
I viewed America in those days with the conceited superiority of the insular Briton, Nevertheless, contact with academic Americans, especially mathematicians, led me to realise the superiority of Germany to England in almost all academic matters. Against my will, in the course of my travels, the belief that everything worth knowing was known at Cambridge gradually wore off. In this respect my travels were very useful to me.
