Biographical Notes

James M. Early was born in 1922 in Syracuse, New York. He received a B.S. in Pulp and Paper Manufacturing from the New York State College of Forestry, Syracuse in 1943. After army service at Ohio State University and the Manhattan Engineer District, Oak Ridge, Tennessee, he returned to O.S.U. as a graduate student and instructor in Electrical Engineering. He received the M.S. (magnetron resonances) in 1948 and the Ph.D. (anisotropic dielectric waveguides) in 1951. Early joined Bell Laboratories in 1951 and during his eighteen years at Bell, he created much of the design theory of bipolar transistors, discovered the effects of space-charge layer widening (the "Early effect"), created the oscillator transistor for the first U.S. satellite, led development of solar cells and transistors for Telstar I, and the development of sealed junction technology as part of Bell Lab's first major IC program. He ended his Bell Labs service as Director of the Electron Device Laboratory at Allentown, Pennsylvania. In September 1969 he joined Fairchild to replace Gordon Moore as Director of the R & D Lab, later known as the Fairchild Research Center. During his tenure, Fairchild created the Isoplanar bipolar process and the first Isoplanar memory products, buried channel CCD imagers, and the 100K series ECL family for high-speed computers. Under his leadership Fairchild installed the first ion implanter in a merchant semiconductor company (1970) and the first commercial electron beam mask-making machine (MEBES 1 - 1977). He became a technical adviser in mid-1983 and retired from Fairchild at the end of 1986. He died in 2004.
