Adrian Klein was an artist and wrote books on photography and cinematography. After serving as an officer in the British Army (he was commissioned a Major in 1921), he became a Fellow of the Royal Photographic Society and changed his name to Adrian Cornwell-Clyne to emphasize his English nationality.
In 1921 he designed a Colour Projector that consisted of a large spectroscope which dispersed spectral lights onto a cinema-type screen - projection was controlled by a keyboard. In 1932, Klein (as he was still known as then) gave a demonstration of the new instrument called a "colour organ" which "was able to project at the will of the player every possible coloured tone in any succession, order or speed". Klein performed many concerts accompanied by music, improvising from a range of over 150 combinations of coloured lights." [from an online source]
