- Westinghouse Lamp Company Experimental Radio Tube, 1920-1921 - Radio engineer McMurdo Silver created six tiny experimental vacuum tubes while employed at Westinghouse Electric in the early 1920s. The tubes were near-duplicates of Western Electric's VT-5s--the original "peanut" tubes. Tubes like these were essential to the low-powered trench radios used in WWI. Silver went on to found Silver-Marshall Inc. and frequently contributed technical articles to radio hobbyist magazines.
