Ghadiali Dinshah

Dinshah P. Ghadiali was born in Bombay, India, in 1873. He studied orthodox medicine, receiving an honorary M. D. in 1899 and earned his doctorate in philosophy. Ghadiali also studied electronics and engineering and earned degrees in electro hydrotherapy, naturopathy, and food science. Ghadiali is best known as the inventor of the spectrochrome, an instrument which he claimed would cure any ailment by shining coloured beams on the affected body parts. These claims led to an investigation by the U.S. Food and Drug Administration and the American Medical Association, resulting in Ghadiali's indictment in 1947. He died in Malaga, New Jersey, in 1966.

Ghadiali moved from India to the United States in 1911 and eventually settled in New Jersey. In 1920, he invented the spectro chrome, a bright light bulb enclosed within a metal box, which emitted rays of light through coloured glass slides. According to Ghadiali, the application of different colours of light could restore balance in the body and cure various ailments without drugs or surgery. Ghadiali established the Spectro Chrome Institute in Malaga, New Jersey, and began marketing his spectro chrome to the public.
