'Daniel David Palmer and Wilhelm Conrad Roentgen were born in the same year, and each of them, at the age of fifty, made the discovery for which he came to be best known. Both of them built upon earlier theories and discoveries. Roentgen's discovery, x-ray, was to become an indispensable diagnostic tool for the profession which grew out of Palmer's discovery, chiropractic.'
