He has been called "the Father of information theory" (Lilley-Trice). His theory "considered the transmission of information as a statistical phenomenon." It gave communications engineers a way to determine the capacity of a communication channel. His theory is not "concerned with the content of information or the message itself" and, therefore, some feel should not be called information theory (Farkas-Conn).

Claude E. Shannon (1916-2001) was an American mathematician and electrical engineer.

Life

Claude Elwood Shannon was born April 30, 1916 in Petosky, MI. He earned a BS in both electrical engineering and mathematics at the University of Michigan in 1936. His Master's thesis in electrical engineering at Massachusetts Institute of Technology (MIT) demonstrated that electrical applications of Boolean algebra could construct any logical numerical relationship, thereby establishing the theory behind digital computing and digital circuits. He also completed a PhD in mathematics at MIT with a dissertation focused on genetics.

In 1940, Shannon became a National Research Fellow at the Institute for Advanced Study in Princeton, NJ. He worked at Bell Labs on fire-control systems and cryptography during World War II under a contract with the National Defense Research Committee. In 1956 Shannon joined the MIT faculty, holding an endowed chair. He worked in the Research Laboratory of Electronics and continued to serve on the MIT faculty until 1978, then as emeritus professor. He died Feb 24, 2001 in Medford, MA.

Contributions

Shannon's extensive contributions to and influence on circuitry, computing, cryptography, artificial intelligence, and much more are covered in detail elsewhere.[1]

Shannon's communication theory built on two insights: (i) That information reflects choices made; and thus reduces uncertainty and (ii) that information is inversely proportional to the amount of uncertainty. Further, probability can be used as a measure of uncertainty.

The relevance of his work to documentation and information services has been widely misunderstood following Warren Weaver's popularization which implied that Shannon's communication theory of the reliability of digital signals could be extended to include the transmission of meaning. Shannon was clear that this was not the case and regretted that his communication theory became known misleadingly as "information theory."
