GenRad Museum Project

Preserving the rich history of GenRad is just as important as preserving its technical documents for reference and at IET we strive to do both. We welcome and value your input. It is important to preserve all that reflects General Radio, so please send us what you have: photos, catalogs, written documentation, personal recollections and we will put them up on this site. We will also put up any original articles, scientific or otherwise. We are also establishing a museum that will contain instruments and documents. This museum will be set up in perpetuity and will not only be for our generation but for generations to come. Please let us know if you would care to generously lend or donate anything that you feel would be of interest.
