R.I.P.: Norman Pickering Perfected The Phonograph

Norman Pickering
Norman C. Pickering, an engineer, inventor and musician whose pursuit of audio clarity and beauty helped make phonograph records and musical instruments sound better, died on Nov. 18 at his home in East Hampton, N.Y.

He was 99, according to The NYTimes.

A man of intellectual energy and wandering curiosity, Mr. Pickering flew planes and designed solutions to help mammoth passenger aircraft manage vibration issues. He played the French horn because a baseball injury to his hand upended his aspiration to be an orchestral violinist. He studied the acoustical properties of stringed instruments, and he aided ophthalmologists by developing an ultrasound method for identifying eye ailments.

Record lovers, however, probably owe him the most. In 1945, Mr. Pickering, who enjoyed listening to records and was frustrated by the sound quality of recordings, developed an improved pickup — that is, the mechanism that includes the phonograph needle, or stylus, and translates the information in the groove of a record into an electrical signal that can be reproduced as sound.

Previous pickups were heavier and more unwieldy; styluses were made of steel, they needed to be replaced frequently, and the weight of the mechanism wore out records after a limited number of plays.

The so-called Pickering pickup (and later, its even more compact iteration, the Pickering cartridge) was introduced just as the favored material for records was shifting from shellac to vinyl, which had a lower playback noise level.



Originally designed for use in broadcast and recording studios, it was a fraction of the size of earlier models, and it replaced the steel of the stylus with a significantly lighter and harder material — sapphire or diamond — which lasted much longer and traced a more feathery path along the record. Because of it, records lasted longer and original sounds were reproduced with less distortion.
