Source-derived summary

George David Forney Jr. (born March 6, 1940) is an American electrical engineer who made contributions in telecommunication system theory, specifically in coding theory and information theory.

Biography

Forney 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 Sc.D thesis introduced the idea of concatenated codes.

He is a member of the United States National Academy of Engineering (1989) and National Academy of Sciences (2003). He is a long-time faculty member at the Massachusetts Institute of Technology.

Among other things, he is generally credited with being the first to recognize the optimality and practical importance of the Viterbi algorithm, and his tutorial paper on the subject is widely cited.

His work in the Viterbi algorithm and in advancing the understanding of coding theory in general influenced the design of modern digital modems.

In 1965 he joined the Codex Corporation. His design resulted in the first mass-produced 9600 bit/s modem introduced in 1971.

Editorial summary

Begin with the source’s own compact description: “Dave Forney” is american information theorist (born 1940). The dossier treats that line as a proposition to test through Dave, Forney and American, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1940, 1961, 1963, 1965—that can be checked directly. The linked authority record independently contributes the date 1940-03-06. For this dossier, Dave, Forney and American is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “american information theorist (born 1940)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 5, 2025. The linked authority identifier is Q5228778. VIAF identifies the subject as 24835932. The Library of Congress control number is n88654770. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1940, 1961, 1963 and 1965.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
