Biography

Harold Chestnut was born in 1918. He studied electrical engineering
Electrical engineering
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical...

  degree in 1940. In that same year he began a life-long career with the General Electric Company, which would last until his retirement in 1983. He married his wife Erma Ruth Callaway Chestnut in 1944 and they had three sons.

During the Second World War Chestnut was both a student and an instructor in General Electric's well-known Advanced Engineering Program. He worked on the design of the central fire-control system and remotely controlled gunturrets used on the B-29 aircraft. Later he worked in the Aeronautics and Ordnance Department and the Systems Engineering and Analysis branch of the Advanced Technology Laboratory, where he served as manager from 1956 to 1972. Here he worked on a wide variety of technical problems including reliability issues in rapid transit and the Apollo mission to the moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

. Later in his career he returned to the field of electric power
Electric power
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt.-Circuits:Electric power, like mechanical power, is represented by the letter P in electrical equations...

 technical committee for another three years. He served as honorary editor from 1969 to 1972 and was the first advisor appointed for life in 1984. Chestnut was also involved in the IEEE since its establishment in 1963 and served as president in 1973. He was active in the formation of the IEEE History Center and the International Federation of Automatic Control.

In 1961 Chestnut edited Automatica: The International Journal on Automatic Control and Automation. He also became editor of a John Wiley book series on systems engineering

 and analysis. In this series Chestnut published his own books.

In the 1980s and 1990s after retirement he created the "Supplemental Ways of Improving International Stability (SWIIS) Foundation" to identify and implement "supplemental ways to improve international stability". He devoted those years to this effort in which he applied principles from the control field, such as stability and feedback, to international political realities.

Harold Chestnut received many awards: In 1966 he received an Honorary Doctorate in engineering from Case Institute of Technology, Cleveland, and in 1972 from Villanova University. In 1984 he won the IEEE Centennial Medal

 and in 1985 the AACC Bellman Heritage Award. Chestnut further in 1981 received the prestigious Honda Prize for ecotechnology, with it a substantial financial award from the Japan’s Honda Foundation. He was further a Fellow of the AIEE, ISA, and AAAS. He was elected to the US National Academy of Engineering in 1974 and selected as a Case Centennial Scholar in 1980.

In 1998 Harold Chestnut and the Chestnut Family provided a gift to IFAC for the IFAC Textbook Prize. The income from this generous gift is used to fund the award for an outstanding textbook author recognized at each IFAC Congress.
