Do you need a miracle cure from "whatever ails ya?" It would appear in 1901, and through the early 1910s, Dr. W.C. Walker may have been the man.
The good doctor would show up at the Lockwood Hotel once a month, working 9 am until 8 pm, where consultations were free. You only had to pay if he could cure you -- I wonder how often that happened! He had "the most successful methods in the treatment of all chronic diseases known to medical science" and was "a friend to the afflicted."
