Percy Wilson was technical adviser to “The Gramophone” magazine from 1924 to 1938, and its technical editor from 1953 to 1966. In November 1924, he established the "Expert Committee" for The Gramophone magazine, gathering the experts of the time to discuss, study and inform the public on the technical improvements in the reproduction of sound. He co-wrote, “Modern Gramophones and Electrical Reproducers,” with George E Webb in 1929, and wrote “The Gramophone Handbook” in 1957. He was a founder-member of the British Sound Recording Association.
Percy Wilson’s contributions were paramount in developments in E.M.G Handmade Gramophones. His exponential formula for the ‘Wilson Panharmonic Horn’ lead to some of the first gramophones with purely scientifically designed horns. His work with Henry Seymour to improve the Seymour tonearm and his many insights into the soundbox, created a standard for later E.M.G & EXPERT products. He was a sharer, someone who inspired and brought together likeminded scientists to achieve a common goal. The dream of creating perfect reproduction of sound.
Through the “Expert Committee”, a regular column in The Gramophone Magazine, Percy Wilson and his fellow Committee members readily offered advice to it readers on all important changes in the reproduction of sound. Percy Wilson wrote numerous papers on the subject even into the late 1960’s.
