Chamberlain's ideas particularly influenced Alfred Rosenberg, who became the Nazi Party's in-house philosopher. In 1909, some months before his 17th birthday, Rosenberg went with an aunt to visit his guardian where several other relatives were gathered. Bored, he went to a book shelf, picked up a copy of Chamberlain's "The Foundations" and wrote of the moment: "I felt electrified; I wrote down the title and went straight to the bookshop." In 1930 Rosenberg published "The Myth of the Twentieth Century," a homage to and continuation of Chamberlain's work. Rosenberg had accompanied Hitler when he called upon Wagner's widow, Cosima, in October 1923 when he met her son-in-law. Hitler told the ailing Chamberlain he was working on his own book which, he intended, should do for the Third Reich what Chamberlain's book had done for the Second.
