Westinghouse Tungsten Lamp, 1908
- 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.

- Westinghouse Experimental Vacuum Tube, circa 1922 - Vacuum tubes appear in older radios, televisions, amplifiers, computers, and other electronic devices. Their function: to amplify and strengthen weak electronic signals. Typical tubes are sealed glass bulbs evacuated of gas, allowing electron flow to be influenced by an interior cathode, plate and grid. Perfected in 1906 by Lee De Forest, the vacuum tube was the genesis of a communications revolution.
