Steam engines drove electric generators, with exhaust steam used for heating and other facilities. The installation used more than two hundred dc motors, and was controlled from a seven-foot (two-meter) high, sixty-foot (eighteen-meter) long switchboard.</div>

Westinghouse Radio Station KDKA was a world pioneer of commercial radio broadcasting. Transmitting with a power of 100 watts on a wavelength of 360 meters, KDKA began scheduled programming with the Harding-Cox Presidential election returns on November 2, 1920. A shed, housing studio and transmitter, was atop the K Building of the Westinghouse East Pittsburgh works. Conceived by C.P. Davis, broadcasting as a public service evolved from Frank Conrad's weekly experimental broadcasts over his amateur radio station 8XK, attracting many regular listeners who had wireless receiving sets.

Experiments performed here have shown that the proton, one of the building blocks of the atom, is in turn composed of smaller particles now called quarks. Other research here has uncovered new families of particles and demonstrated subtle effects of the weak nuclear force. This research requires the utmost precision in the large and unique electromechanical devices and systems that accelerate, define, deliver and store the beams of particles, and in the detectors that analyze the results of the particle interactions.

On this site during the 1939-45 World War, 12,000 men and women broke the German Lorenz and Enigma ciphers, as well as Japanese and Italian codes and ciphers. They used innovative mathematical analysis and were assisted by two computing machines developed here by teams led by Alan Turing: the electro-mechanical Bombe developed with Gordon Welchman, and the electronic Colossus designed by Tommy Flowers. These achievements greatly shortened the war, thereby saving countless lives.

During the winter of 1957-58, Earl E. Bakken developed the first wearable transistorized pacemaker, the request of heart surgeon, Dr. C. Walton Lillehei. As earlier pacemakers were AC-powered, this battery-powered device liberated patients from their power-cord tethers. The wearable pacemaker was a significant step in the evolution to fully-implantable units.

On December 12, 1901, a radio transmission of the Morse code letter 'S' was broadcast from this site, using equipment built by John Ambrose Fleming. At Signal Hill in Newfoundland, Guglielmo Marconi, using a wire antenna kept aloft by a kite, confirmed the reception of these first transatlantic radio signals. These experiments showed that radio signals could propagate far beyond the horizon, giving radio a new global dimension for communications in the twentieth century.

This achievement altered for all time personal, commercial, and political relations between peoples on the two sides of the ocean. Five more cables between Heart's Content and Valentia, Ireland were completed between 1866 and 1894. This station continued in operation until 1965.</div>

July 17, 1909, the Shoshone Transmission Line began service carrying power, generated by the Shoshone Hydroelectric Generating Station, to Denver. The Line operated at 90 kV, was 153.4 miles long, and crossed the Continental Divide three times reaching an altitude of 13,500 feet. Its design and construction represented an outstanding electrical engineering accomplishment due to its length, the mountainous country over which it was constructed, and the unusually severe weather conditions under which it operated.

In this building in January 1838, Samuel F. B. Morse and Alfred Vail first demonstrated publicly crucial elements of their telegraph system, using instruments that Vail had constructed during the previous months. Electrical pulses, transmitted through two miles of wire, caused an electromagnet to ink dots and dashes (grouped to represent letters and words) on a strip of paper. Commercialization began in 1844 when funding became available.

In 1933, the police department in Bayonne, New Jersey initiated regular two-way communications with its patrol cars, a major advance over previous one-way systems. The very high frequency system developed by radio engineer Frank A. Gunther and station operator Vincent J. Doyle placed transmitters in patrol cars to enable patrolmen to communicate with headquarters and other cars instead of just receiving calls. Two-way police radio became standard throughout the country following the success of the Bayonne system.

In 1945, Marcellus Merrill first implemented an electronic dynamic wheel-balancing system. Previously, all mechanical methods were static in nature and required removing the wheels from the vehicle. Merrill's innovative balancing system came to be widely used internationally. Elements of the dynamic balancing systems are still used today, primarily for industrial and automotive production applications.
