In the Troy directory for 1860, we find this listing for Mrs. Mary Entwistle, Clairvoyant Physician. She lived at 611 River Street, and that is all we want to know about her. Jaded readers will be unsurprised to learn that some clairvoyant physicians were subject to malpractice suits. It would be nice to think we’ve moved past this, but of course we haven’t.
