G. David Forney, Jr.

G. David Forney, Jr. was born in New York, NY, on 6 March 1940. He received the B.S.E. degree in Electrical Engineering from Princeton University in 1961, summa cum laude, and the M.S. and Sc.D degrees in Electrical Engineering from the Massachusetts Institute of Technology in 1963 and 1965, respectively. His doctoral thesis, Concatenated Codes, was published as an M.I.T. Press monograph in 1966.

Forney joined Codex Corporation in 1965 as its thirteenth employee. During the next five years, he worked primarily on applications of convolutional codes to deep space and satellite communication applications. Under contract from NASA Ames, Forney designed the sequential decoding system for the Pioneer mission to the outer planets. During this period he introduced the representation of convolutional codes by trellis diagrams, and proved the optimality of the Viterbi algorithm.

In 1970-71, Forney was the principal designer of a family of high-speed telephone-line data modems, including the first commercially successful 9600 bps modem (Codex 9600C), which later became the basis of the international standard CCITT Recommendation V.29. He became Vice President of Research and a member of the Board of Directors of Codex in 1970. He spent the academic year 1971-72 at Stanford University, where he developed information theory course notes that enjoyed wide circulation. Upon his return to Codex, he led the development of the next generation of modem products and Codex's first networking products, both announced in 1975.

In 1975, Dr. Forney became Vice President of Research and Development for Codex, and oversaw the further development of its data communications product line. Codex was acquired by Motorola, Inc. in 1977. Over the next nine years he held various Codex and Motorola management positions, including Vice President and Director of Technology and Planning of Motorola's Information Systems Group during 1982-86.

Dr. Forney returned to full-time technical work in 1986 as a Vice President of the Technical Staff of Motorola, based at Codex. In recent years, he has been working on the fundamental theory of trellis coded modulation, while contributing to advancing commercial telephone-line modem speeds to 19.2 kb/s and beyond. He is currently participating in the development of the CCITT Recommendation 'V.fast' for dial modems at 19.2 kb / s and above.

Forney was Editor of the IEEE Transactions on Information Theory during 1970-73. He was a member of the Board of Governors of the IEEE Information Theory Group from 1970-76, and organized the IEEE-USSR Information Theory Workshop in Moscow in 1976. He has served on the Board of Governors of the Information Theory Society since 1986, and as President in 1992.

He received the IEEE Information Theory Group Prize Paper Award in 1970, the IEEE Browder J. Thompson Memorial Prize Award in 1972, the IEEE Centennial Medal in 1984, and the IEEE Donald G. Fink Prize Award in 1990 and 2009, and the IEEE Edison Medal in 1992 'For original contributions to coding, modulation, data communication modems, and for industrial and research leadership in communications technology.' He was elected a Fellow of the IEEE in 1973, and a member of the National Academy of Engineering (U.S.A.) in 1983.
