Ruth Beymer Drown (October 21, 1891 – March 13, 1965) born in Colorado was an American alternative medicine practitioner, chiropractor and proponent of radionics. She invented radio devices which she claimed could cure any patient in the world, just from blood-sampling. Drown was investigated by the California State Bureau of Food and Drug Inspection and charged with grand theft in 1963. Investigators claim her radiotherapy used worthless electrical devices to treat non-existent ailments. Drown died before the case came to trial.
