By this time Chamberlain had met his first wife, the Prussian Anna Horst, whom he would divorce in 1905 after 28 years of marriage. Chamberlain was an admirer of Richard Wagner, and wrote several commentaries on his works including "Notes sur Lohengrin " ("Notes on Lohengrin") (1892), an analysis of Wagner's drama (1892), and a biography (1895), emphasising in particular the heroic Teutonic aspects in the composer's works. Stewart Spencer, writing in "Wagner Remembered", described Chamberlain's edition of Wagner letters as "one of the most egregious attempts in the history of musicology to misrepresent an artist by systematically censoring his correspondence". In particular, Wagner's lively sex life presented a problem for Chamberlain. Wagner had abandoned his first wife Minna, had an open affair with the married woman Mathilde Wesendonck and had started sleeping with his second wife Cosima while she was still married to her first husband. Chamberlain in his Wagner biography went to considerable lengths to distort the Master's love-life such as implying that Wagner's relationship with Cosima von Bülow only started after the death of her first husband.
