27 Claude Shannon, oral history with Robert Price, IEEE.
28 “We had an internal distribution system,” recalls a Bell Labs mathematician, Brock McMillan, who worked in the office next to Shannon’s at Murray Hill at the time. “So people in the math department could read things before publication. Shannon was not particularly talkative. He talked to us about his theories maybe a little bit. But that 1948 paper caught me almost stone cold.” Most of the Bell researchers, with the exception of Shannon’s friend Barney Oliver, experienced a similar sense of shock. John Pierce likened the surprise he felt upon encountering his friend’s ideas to the dropping of a powerful explosive.

32 John Robinson Pierce, quoted in M. Mitchell Waldrop, “Claude Shannon: Reluctant Father of the Digital Age,”
Technology Review
, January 7, 2002. For my explication of information theory, I owe a debt to a number of people who have written on Shannon’s theory: John Pierce, Warren Weaver, David Kahn, Robert Gallager, Bob Lucky, Neil Sloane, Aaron Wyner, John Horgan, Wiliam Poundstone, and Erico Marui Guizzo. Before me, Pierce, Poundstone, and Guizzo also made the insightful point juxtaposing the reduction of redundancy in cryptanalysis with the addition of redundancy in coding. Finally, Shannon was especially eloquent on the genesis and meaning of his own work in his speeches throughout the 1950s, which were rich with metaphors to explain his ideas; in his interviews with Robert Price and Anthony Liversidge; and (later still) in his Kyoto prize speech in 1985.
33 Richard Hamming and David Slepian are most often credited for their work on these codes.
34 Waldrop, “Claude Shannon: Reluctant Father of the Digital Age.” As Bob Gallager at MIT points out, communications engineers (Fano included) had long understood that errors could be reduced by increasing the power of a transmission and/or increasing the channel capacity—that is, the “bandwidth” through which transmissions moved. Shannon’s great breakthrough was in showing that they could reduce errors without doing either.

42 Liversidge, “Profile of Claude Shannon.” When asked, “Can Bell Labs take credit to some extent for your achievement?” Shannon answered, “I think so. If I had been in another company, more aimed at a particular goal, I wouldn’t have had the freedom to work that way.”
43 Walter Brattain conceded this in a 1963 oral history interview with Harriet Zuckerman, Columbia University Oral History Research Office.

13 THROBAC stands for “THrifty ROman numeral BAckward-looking Computer.” Shannon later admitted that the name (and to some extent the calculator itself) was inspired by the era’s computer acronyms—ENIAC, UNIVAC, and so on. Unlike some of Shannon’s other machines, which are now owned by the MIT Museum, his original “ultimate machine,” with the mechanical hand, has been lost, according to his wife, Betty.

21 Shannon’s work on cryptography with the NSA probably did not continue beyond the 1960s. Even in the 1980s, though, he was forbidden to speak of it—a hallmark of the secrecy obligations that involve any type of work with the NSA. In response to a Freedom of Information Act request by this book’s author, the NSA responded that “Dr. Shannon was never an affiliate of NSA. He was, however, involved as a consultant to
NSA as a member of various committees.” Documents demonstrate that while Shannon was still at Bell Labs he was at least involved with the Mathematics Panel of the National Security Agency Scientific Advisory Board (NSASAB). When asked by Bob Price during an oral history many years later about his National Security Agency contributions, Shannon replied, “I was a consultant. I probably should … I don’t know … I think, I don’t know that I have any … even though this was a long time ago, I’d better not talk about …” Claude Shannon, oral history with Robert Price, IEEE.

It is by all means possible that a Bell Labs scientist used the word “innovation” before 1958. However, in a review of thousands of Bell Labs documents and hundreds of speeches from the 1950s, the first instance I came across was in a speech by Jack Morton, “Some Thoughts About the Future,” at the tenth anniversary of the transistor, June 17, 1958. “In the past,” Morton remarked, “American industry has led the world because we have used existing knowledge with ingenuity, energy and innovation.” Perhaps simultaneously, John R. Pierce began using the word, too. “Innovation in Technology,” an essay by Pierce, appeared in the September 1958 issue of
Scientific American
. Moreover, a draft of a paper of Pierce’s later titled “Myths of Creation,” dated September 10, 1958, was originally titled “On Innovation in Science.”

Some of the most acclaimed Bell Labs scientists would often stand amazed by the talents of their technical assistants. For Morris Tanenbaum, for instance, it was Ernie Buehler, who was adept at growing crystals.

Labs where he is next in line to become president upon the expected retirement of Dr. Oliver Buckley in about a year and a half.”

Ernest Braun and Stuart Macdonald sum up the military’s reasons concisely: “The military in the early fifties was not primarily concerned with price. Instead it was more concerned with such matters as availability, whether performance could match military specifications, and whether semiconductor devices would be reliable. … One considerable attraction of the new devices was the reduction in weight they offered,
both in the components themselves and in the batteries of power supplies required.” Ernest Braun and Stuart Macdonald,

(Cambridge: Cambridge University Press, 1982), p. 70.
