Harold Alden Wheeler (10 May 1903 – 25 April 1996) was a noted

electrical engineer
.

Early life and education

Harold A. Wheeler was born in Saint Paul, Minnesota, to William Archibald Wheeler and Harriet Marie Alden Wheeler (a descendant of John and Priscilla Alden).

In 1925 Wheeler graduated from

Ruggles Prize for excellence in Mathematics. Subsequently, he studied physics at Johns Hopkins University
until 1928.

During his education he worked part-time at the

National Bureau of Standards' Radio Laboratory, then from 1922 onwards at Stevens Institute of Technology, with Prof. Louis Alan Hazeltine, after discovering that they had independently invented the Neutrodyne
receiver. (It entered large-scale production in 1923, and was the dominant receiver for most of the 1920s.)

Career

In 1924 he became

automatic volume control that maintained a constant sound level while tuning to broadcasts of differing strengths. AM radio receivers incorporating this circuit came into use about 1930, and it has been included in every set since. He led the Hazeltine laboratory 1930–1939, and during this time received patents for 126 inventions on a wide range of work including circuits, test equipment, acoustics, antennas, transmission lines, methods of calculation for inductance of coils (included in all relevant textbooks since the mid-1930s), skin effect, coupled circuit theory, television
scanning theory, and analysis and design of wide-band TV amplifiers.

During World War II Wheeler led work on identification friend or foe (IFF) antennas for aircraft, surface vessels, submarines, and ground stations. By war's end, these "lifesaver antennas" had been placed on all Allied ships.

In 1946 he founded Wheeler Laboratories to develop microwave circuits and antennas for missile systems tracking and guidance radar. In 1959, when it became a Hazeltine subsidiary, he was named a Hazeltine director and vice-president.

Honours

All told, Wheeler held 180 United States patents and received over fifty awards. He was a member of the National Academy of Engineering, a fellow of the Institute of Radio Engineers (1927) and of the American Institute of Electrical Engineers (1946), and awarded the IEEE Morris N. Liebmann Memorial Award in 1940 "for his contribution to the analysis of wide-band high-frequency circuits particularly suitable for television", and the IEEE Medal of Honor in 1964 "for his analyses of the fundamental limitations on the resolution in television systems and on wideband amplifiers, and for his basic contributions to the theory and development of antennas, microwave elements, circuits, and receivers."

Wheeler was also a member of Sigma Xi, Tau Beta Pi, and the Defense Science Board.
