The Hardy-Goldthwaite organ was a type of early analogue sampler, similar to the Welte Licht-Ton Orgel, The Superpiano and several other photo-electrical instruments of the period and was developed by the physicists Arthur Hardy and Sherwood Brown at the Massachusetts Institute of Technology at the request of DuVal R. Goldthwaite, chairman of the Interchemical Corporation (who apparently had originated the concept after working with Hardy on colour and ink chemistry). At the heart of the instrument was a single optical disc of photographed sound waves. The discs, created from translations of original instrumental sounds, rotate between a light a slit and a photo-electrical cell generating voltage outputs of various timbres. A small three octave manual keyboard operated a shutter within the instrument that projected a light beam through the specific tone on the disc correlating to the key’s pitch.
The instrument was said to be able to produce the timbres of an organ, trumpet, piano and strings – with the possibility of reproducing any sound that could be recorded to the glass disc.
Arthur C. Hardy born Worcester, Massachusetts:1895 died: 1977.
Arthur Hardy was a physicist best know for his work with spectrometers and colour analysers and was the author of the default text on the subject ‘The Principles of Optics’ . After the WWI Hardy worked at Kodak Research Labs and then transferred to Massachusetts Institute of Technology where he became chair of MIT’s physics department.
Hardy became president of the Optical Society of America from 1935-36 and in 1935 Hardy filed a patent for the first spectrophotometer – a device for measuring and recording colour values. It could detect two million different shades of colour and make a permanent record chart of the results. The patent was assigned to the General Electric Company of Schenectady, N.Y. which sold the first machine on 24 May 1935. It used a photo-electric device to receive light alternately from a sample and from a standard for comparison.
After the outbreak of WWII Hardy founded the ‘Visibility Laboratory’ which focused on applying optics to such problems as camouflage, misdirection of aerial bombardment, target location, visibility of submerged objects at sea.
