On the surface he [Dr. Charles Bonnier] seemed to be incongruously versatile; he wrote poetry, prose philosophy, belles-lettres, articles on socialism (of the French type) and he painted pictures in the pointilliste style.  But the strangest of all his activities was connected with his intense love of Wagner.  In a loud tenor voice he would sing stretches of the Wagnerian operas, the while he would accompany himself on – of all things – a harmonium!  (Not when I was trying to compose, of course).  This instrument reposed incongruously in his own sitting-room, on the walls of which he had hung enormous French posters by Toulouse-Lautrec of ballet-dancers, or maybe they were prostitutes, displaying a large expanse of leg and white drawers.
