Of course, Chamberlain basically picked up on all that had been said previously (re: Aryan superiority and the decadence of the Semitic race) by Gustave Klemm in the 1840's as well as French scholar Ernest Renan and Swiss philologist Adolphe Pictet back in the late 1850's. Speaking of Switzerland, did you know that HSC first heard Wagner's name during a boat trip on Lake Lucerne in 1870? Just a little fun fact.
