Royal R. Rife

Royal Raymond Rife (May 16, 1888 - August 5, 1971) was an American inventor who developed specialised optical microscopes for high-magnification photography and microcinematography, including several that he asserted allowed him to view particular micro-organisms he believed responsible for disease, and the Rife Beam Ray device, a gas-filled ray tube that he argued would eliminate these micro-organisms by exposing them to electromagnetic waves oscillating at specific frequencies that he called the Mortal Oscillatory Rates.
