Extractions: Claude Shannon, Father of Information Theory, Dies at 84 Claude Shannon's clever electromechanical mouse, which he called Theseus, was one of the earliest attempts to "teach" a machine to "learn" and one of the first experiments in artificial intelligence. (This photograph is also available at higher resolution for use in print reproduction.) Murray Hill, N.J. (Feb. 26, 2001) Claude Elwood Shannon, the mathematician who laid the foundation of modern information theory while working at Bell Labs in the 1940s, died on Saturday. He was 84. Shannon's theories are as relevant today as they were when he first formulated them. "It was truly visionary thinking," said Arun Netravali, president of Lucent Technologies' Bell Labs. "As if assuming that inexpensive, high-speed processing would come to pass, Shannon figured out the upper limits on communication rates. First in telephone channels, then in optical communications, and now in wireless, Shannon has had the utmost value in defining the engineering limits we face." In 1948 Shannon published his landmark A Mathematical Theory of Communication . He begins this pioneering paper on information theory by observing that "the fundamental problem of communication is that of reproducing at one point either exactly or approximately a message selected at another point." He then proceeds to so thoroughly establish the foundations of information theory that his framework and terminology remain standard.

Extractions: I n 1936, graduate student Claude Shannon arrived at the Massachusetts Institute of Technology. In the best tradition of grad. students, Shannon was short of money, and happy to be recruited by his professor, Vannevar Bush, to tend the unwieldy entrails of Bush's mechanical computing device - the Differential Analyser. The Differential Analyser, while a marvel of scientific engineering for its time, was a lot of hard work to maintain. Basically an assembly of shafts and gears, the gears themselves had to be manually configured to specific ratios before any problem could be fed to the machine - a boring, laborious - and extremely messy - business. (I had to kind of, you know, fix [it] from time to time to keep it going.) Encouraged by Bush to base his master's thesis on the logical operation of the Differential Analyser, Shannon inevitably considered ways of improving it, perhaps by using electrical circuits instead of the present cumbersome collection of mechanical parts. Not long afterwards, it dawned on Shannon that the Boolean algebra he'd learned as an undergraduate was in fact very similar to an electric circuit. The next obvious step would be to lay out circuitry according to Boolean principles, allowing the circuits to binary-test propositions as well as calculate problems.

Extractions: Claude E Shannon 's father was also named Claude Elwood Shannon and his mother was Mabel Catherine Wolf. Shannon was a graduate of the University of Michigan, being awarded a degree in mathematics and electrical engineering in 1936. He then went to the Massachusetts Institute of Technology where he obtained a Master's Degree in electrical engineering and his Ph.D. in mathematics in 1940. Shannon wrote a Master's thesis A Symbolic Analysis of Relay and Switching Circuits on the use of Boole 's algebra to analyse and optimise relay switching circuits. His doctoral thesis was on theoretical genetics. At the Massachusetts Institute of Technology he also worked on the differential analyser, an early type of mechanical computer developed by Vannevar Bush for obtaining numerical solutions to ordinary differential equations . Shannon published Mathematical theory of the differential analyzer in 1941. In the introduction to the paper he writes:-

Extractions: Claude Shannon's creation in the 1940's of the subject of information theory is arguably one of the great intellectual achievements of the twentieth century. Information theory has had an important and significant influence on mathematics, particularly on probability theory and ergodic theory, and Shannon's mathematics is in its own right a considerable and profound contribution to pure mathematics. But Shannon did his work primarily in the context of communication engineering, and it is in this area that it stands as a unique monument. In his classical paper of 1948 and its sequels, he formulated a model of a communication system that is distinctive for its generality as well as for its amenability to mathematical analysis. He formulated the central problems of theoretical interest, and gave a brilliant and elegant solution to these problems. We preface this section of his collected works with a very short description of this pioneering work. Let us look first at his model. Shannon saw the communication process as essentially stochastic in nature. The semantic meaning of information plays no role in the theory. In the Shannon paradigm, information from a "source" (defined as a stochastic process) must be transmitted though a "channel" (defined by a transition probability law relating the channel output to the input). The system designer is allowed to place a device called an "encoder" between the source and channel which can introduce a fixed though finite (coding) delay. A "decoder" can be placed at the output of the channel. The theory seeks to answer questions such as how rapidly or reliably can the information from the source be transmitted over the channel, when one is allowed to optimize with respect to the encoder/decoder?

It is difficult to overstate the impact which Claude Shannon has had on the 20th century and the way we live and work in it, yet he remains practically unknown to the general public. Shannon spent the bulk of his career, a span of over 30 years from 1941 to 1972, at Bell Labs where he worked as a mathematician dedicated to research. While a graduate student at MIT in the late 1930s, Shannon worked for Vannevar Bush who was at that time building a mechanical computer, the Differential Analyser. Shannon had the insight to apply the two-valued Boolean logic to electrical circuits (which could be in either of two states - on or off). This syncretism of two hitherto distinct fields earned Shannon his MS in 1937 and his doctorate in 1940.

Wyner, is one of two biographies of Claude Shannon that appears in the book we edited, Shannon's Collected Papers Claude Elwood Shannon was born in Petoskey, Michigan, on Sunday, April 30, 1916. His father, Claude Sr. (1862-1934), a descendant of early New Jersey settlers, was a businessman and, for a period, Judge of Probate. His mother, Mabel Wolf Shannon (1880-1945), daughter of German immigrants, was a language teacher and for a number of years Principal of Gaylord High School, in Gaylord, Michigan. The first sixteen years of Shannon's life were spent in Gaylord, where he attended the Public School, graduating from Gaylord High School in 1932. As a boy, Shannon showed an inclination toward things mechanical. His best subjects in school were science and mathematics, and at home he constructed such devices as model planes, a radio-controlled model boat and a telegraph system to a friend's house half a mile away. The telegraph made opportunistic use of two barbed wires around a nearby pasture. He earned spending money from a paper route and delivering telegrams, as well as repairing radios for a local department store. His childhood hero was Edison, who he later learned was a distant cousin. Both were descendants of John Ogden, an important colonial leader and the ancestor of many distinguished people. Shannon's recent hero list, without deleting Edison, includes more academic types such as Newton, Darwin, Einstein and Von Neumann.

Extractions: This entry contributed by Rethnakaran Pulikkoonattu American mathematician and father of information theory . Claude Elwood Shannon was born in Gaylord, Michigan on April 30, 1916 to Claude Elwood and Mabel Wolf Shannon. Shannon's father Claude, was a judge in Gaylord, a small town with a population of about three thousand, and his mother Mabel was the principal of the local high school. Although he didn't work in the field of mathematics, Shannon proved to be mathematically precocious. Although there was not much scientific influence from Shannon's father, he received scientific encouragement from his grandfather, who was an inventor and a farmer whose inventions included the washing machine and farming machinery. While at MIT, Shannon studied with both Wiener and Bush. Noted as a 'tinkerer,' he was ideally suited to working on the Differential Analyzer, and would set it up to run equations for other scientists. At Bush's suggestion, Shannon also studied the operation of the analyzer's relay circuits for his master's thesis. This analysis formed the basis for Shannon's influential 1938 paper "A Symbolic Analysis of Relay and Switching Circuits," in which he put forth his developing theories on the relationship of symbolic logic to relay circuits. This paper, and the theories it contained, would have a seminal impact on the development of information processing machines and systems in the years to come.

Extractions: Professor Shannon, a distant relative of Thomas Edison, was affiliated with Bell Laboratories from 1941 to 1972, during which time he wrote the landmark A Mathematical Theory of Communication (1948). This pioneering paper on information theory begins by observing that "the fundamental problem of communication is that of reproducing at one point either exactly or approximately a message selected at another point." The information content of a message, he theorized, consists simply of the number of 1s and 0s it takes to transmit it. "Nobody had come close to this idea before," said MIT Professor emeritus Robert G. Gallager, who worked with Professor Shannon. "This was not something somebody else would have done for a very long time." The revolutionary idea was gradually adopted by communications engineers and stimulated the technology which led to today's information age. All communication lines today are measured in bits per second, the notion that Professor Shannon made precise with "channel capacity." His theory also made it possible to use bits in computer storage needed for pictures, voice streams and other data. After receiving BS degrees in mathematics and electrical engineering from the University of Michigan in 1936, he came to MIT as a graduate student. As a part-time job, he worked on Professor Vannevar Bush’s differential analyzer. His master's thesis, "A Symbolic Analysis of Relay and Switching Circuits," used Boolean algebra—in which problems are solved by manipulating two symbols, 1 and 0—to establish the theoretical underpinnings of digital circuits. This work was the beginning of modern switching theory. Harvard University Professor Howard Gardner called it "possibly the most important, and also the most famous, master’s thesis of the century."

One final note, the editor of this book was Wilbur Schramm, the head of the first Institute of Communication Research at the University of Illinois. This book heavily influenced Schramm, as seen later in this essay (see Schramm von Bertalanffy, Ludwig (1988). General system theory: Foundations, development, applications. Most notable is the theory of an organism as open system (published originally in 1940). This notion of open system "pried the lid off" of previous closed systems thinking and necessitated the incorporation of environment and culture in our scientific endeavors. Rapoport, Anatol. Fights, games, and debate s (1960). Ann Arbor, MI: The University of Michigan Press. Rapoport was one of the foremost game theoreticians. He looked for "different kinds of intellectual tools for the analysis of conflict situations (p. 12)." His last two chapters entitled, the "case for individualism" and the "case for collectivism" precede Hofstede's similar concept used today in intercultural communication. Rapoport claims it is the tension between cooperation and competition that provides conflict situations. In a recent (1985) book by Axelrod, Rapoport won a computer-simulated prisoner's dilemma contest by submitting a tit-for-tat solution (i.e., cooperation). Axelrod theorized that cooperation is the best strategy in solving prisoner dilemma-type conflicts. Rapoport helped us think twice about games and how they can serve as practical aids in the study of communication.

Extractions: for INFO NATION "We want information...information..." Number Two, in "The Prisoner" Claude Shannon isn't well known to the public at large, but he is one of a handful of scientists and thinkers who made our world of instant communications possible. Born in Gaylord, Michigan in 1916, into a fairly well-educated and intellectually stimulating environment, his younger days were spent working with radio kits and morse code, an early start to a promising career. (Later, he would remember Edgar Allan Poe's story "The Gold Bug", with its simple cryptogram, as another early influence.) In the late 1930s at MIT, he did important work showing how logic could be applied to the design of relay circuitsin short, that the true-and-false of Boolean logic could be the same as the on-and-off of an electric switch. For this pioneering work, important for both phones and computers, Shannon received his doctorate in 1940. Shannon then spent 31 years at Bell Labs , starting in 1941. Among the many things Shannon worked on there, one great conceptual leap stands out. In 1948, Shannon published "The Mathematical Theory of Communication" in the Bell System Technical Journal, along with Warren Weaver. This surprisingly readable (for a technical paper) document is the basis for what we now call information theorya field that has made all modern electronic communications possible, and could lead to astounding insights about the physical world and ourselves.
