'''Sidney Darlington''' (July 18, 1906 &ndash; October 31, 1997) was an American electrical engineer and inventor of a [[transistor]] configuration in 1953, the [[Darlington transistor|Darlington pair]]. He advanced the state of [[network theory]], developing the insertion-loss synthesis approach, invented [[pulse compression|chirp radar]], and contributed to the designs of [[bombsight]]s and gun and rocket [[Guidance system|guidance]].

Darlington was awarded a B.S. in physics, magna cum laude, from Harvard in 1928, where he was elected to [[Phi Beta Kappa]]. He also received a B.S. in E.E. from MIT in 1929, and a Ph.D. in physics from Columbia in 1940.<ref>{{Cite web|url=http://www.ieeeghn.org/wiki/index.php/Sidney_Darlington|title = Sidney Darlington - Engineering and Technology History Wiki|date = 14 August 2017}}</ref>

In 1945, he was awarded the [[Presidential Medal of Freedom]], the United States' highest civilian honor, for his contributions during World War II. He was an elected member of the [[National Academy of Engineering]], which cited his contributions to electrical network theory, radar, and guidance systems. In 1975, he received [[IEEE]]'s [[Edison Medal]] "For basic contributions to network theory and for important inventions in radar systems and electronic circuits" and the [[IEEE Medal of Honor]] in 1981 "For fundamental contributions to filtering and signal processing leading to chirp radar".

He died at his home in [[Exeter, New Hampshire]], USA, at the age of 91.
