I seem to remember his name coming up on several threads asking about historical people who might be ASpies. Samuel Clemens visited him, and remarked on how quiet and shy he was. (Of course, compared to how rowdy Clemens was, most people would come across as shy.)
As to the pedaphile thing, it is documented that he took nude photos of young girls, but they were more artistic than pornagraphic. I believe I read that he asked in his will for all the photos to be destroyed after his death, but some have survived.
