From the town of Minerva, Ohio, Fremont D. Davis, D.D.S. (left), advertised painless dentistry “by the use of pure Nitrous Oxide Gas” (right). Sadly, his personal health was hardly pain free. While driving back into Minerva, Dr. Davis’s buggy was struck after a railroad flatcar bumped into a switch.
