It's taken a while, but you can now read Lewis Edson Waterman's Long Strange Trip.
Stranger than fiction -- did you know that the books the young Waterman was peddling were those of Fowler & Wells, leading promoters of Victorian quackery (Phrenology, food faddism, Spiritualism, and more)? And that he was a keen supporter of phrenology to the end of his life? Further, that he spent his early years in New York promoting a weightlifting fitness system?
There's yet more to come, believe it or not.
