James M. Early (July 25, 1922 – January 12, 2004) was an American electrical engineer, best known for his work on transistors and charge-coupled device imagers.
[1] The Early effect in bipolar junction transistors is due to an effective decrease in the base width because of the widening of the base-collector depletion region, resulting in an increase in the collector current with an increase in the collector voltage.
The same type of length modulation in MOSFETs is also commonly referred to as Early effect.
Early was the first to make a transistor that would oscillate faster than "a thousand megacycles" (1 GHz), circa 1952, for which feat he won a bottle of Scotch whisky from John Robinson Pierce.
He also developed the transistors for America's first commercial communications satellite, the Telstar I.
