The Idea Factory is a well written presentation of what happened in Bell Laboratories in its early and middle lifetime. The author has captured the view from within the Lab and has presented a history that is in many ways presented in a manner in which the Lab people would have wanted it presented. His conclusions however are subject to significant debate, if not being downright wrong.I write this review also having heard the author present his work in Madison, NJ to an audience almost totally filled with hundreds of former Labs staff and also as one who spent a great deal of time at the Labs from 1964 through 1972, while going back and forth to MIT, plus over fifty years in the industry.The author presents the often told tales of Shockley and the transistor, Shannon and information theory, as well as all the management types who formed, directed, and molded the Lab like Kelley and others. Many of these people I knew firsthand and as any observer the view is all too often colored by one's position at the time.The driving presumption of the author is best stated in his introduction where he says:"Some contemporary thinkers would lead us to believe that twenty-first century innovation can only be accomplished by small groups of nimble profit seeking entrepreneurs working amid the frenzy of market competition. Those idea factories of the past, and perhaps their most gifted employees, have no lessons for those of us enmeshed in today's complex world. This is too simplistic. To consider what occurred at Bell Labs, to glimpse the inner workings of its invisible and now vanished "production lines" is to consider the possibilities of what large human organizations might accomplish."This conclusion is frankly a significant over-reach, if not just out right wrong, since it is posited without any basis in fact contained within the book. The author never really looks at the many other parts of the Lab, the tens of thousands who worked on miniscule parts of large systems. The R&D group at Murray Hill was but a tiny part of an enterprise whose overall goal was to ensure the monopoly that AT&T had been granted by the Federal Government and to maximize the profit made in that monopoly.To understand one must recognize that in the old Bell System profit was defined as a return on investment, meaning the invested plant. Revenue thus equaled expense, plus depreciation plus that profit construct; namely the company could charge whatever it wanted to subject to the regulators limited control. The game was thus to maximize profit, which in turn meant to maximize the invested plant, and not to be maximally efficient in a competitive sense, there was no competition. Understanding the ground rules of the old Bell System is essential to the understanding of Bell Labs. No other company, save perhaps the power utilities, functioned in such a manner. This was the basis of the world view of the Labs, a world of monopolistic control.But the "creative destruction" of the free market did begin to surround the Labs. It surrounded the Labs in the areas in which the author appears paradoxically to make them most successful. Let me discuss just three examples.Satellite Communications: The author speaks glowingly of Pierce and his vision of satellite communications. Yet Pierce wanted dozens of low orbit satellites, apparently driven by his desire to have low time delay for voice. He wrote a paper which appeared in Scientific American proselytizing the idea. Based upon that proposal, COMSAT was formed and capitalized based upon a need for this massive investment not only in space segment but also in the complex tracking earth stations. A few days after the COMSAT IPO Hal Rosen and his team at Hughes launched Syncom I, the first synchronous satellite. Within weeks they launched Syncom II. Synchronous satellites provided global coverage with only three satellites, not the dozens demanded by Pierce's world view. COMSAT was then off with its own satellite, Intelsat 1 and its progeny using not Pierce, but Rosen. Somehow this minor fact is missing from the book.Digital Switching: Fred Kappel was the Chairman of AT&T in the 60s during the time of the development of the first Electronic Switching System, the No 1 ESS. This system was developed by people such as Ray Ketchledge and others. They had deployed a computer based system, albeit still with analog mechanical switches called Fereeds. Fereeds were small mechanical switches that clicked and clacked. The Fereeds made the new computer elements be the dog still wagged by this old technological tail cross-connection technology. Kappel wanted an all-digital switch and the Labs kept putting him off. But at the time he had another card up his sleeve. AT&T also owned Bell Canada and their Bell Labs entity called Bell Northern Research. So off he went and got them to build the all-digital switch. The entity doing it became Northern Telecom, NORTEL. NORTEL subsequently became a major switch supplier of their new and better switches to the Operating Companies. Thus, in a true sense, Kappel used the entrepreneurial spirit of the Canadians to do what the mass of people at Bell Labs would not do.The Internet: Now in the mid-1970s the ARPA net was in early development and some of the basic principles were evolving from Government, Academia, and a bunch of small start-up companies like Linkabit and BB&N. ARPA, the DOD advanced research arm had an office called IPTO and they wanted to expand the Internet more aggressively using the public telephone network. Yet since AT&T was a monopoly they somehow had to co-opt AT&T to agree. A first step was to go to a meeting at Murray Hill and seek their support. So off go a couple of folks from ARPA and in Murray Hill they met the standard Bell System meeting of a few dozen people. The senior person, a VP I was told, began to lecture them that if they wanted this accomplished just send them the money and they would deliver what they felt was the correct design. The ARPA folks walked away somewhat aghast and immediately reached the conclusion that they would develop what became the Internet, totally independent of AT&T. This was, in a sense, the final straw since it sowed, in my opinion, the seeds for AT&T's ultimate destruction, not the Judge Greene breakup.The author, in my opinion, misses many other R&D entities which had a significant role in the evolution of technology, oftentimes well exceeding Bell Labs. Let me discuss just a few:MIT Rad Lab: At the beginning of WW II Vannevar Bush set out to establish a center for R&D focusing on radar. Bell Labs had tried to capture this jewel but Bush wanted a more innovative and competitive center and as such he chose MIT and from that came the Rad Lab. The Rad Lab was composed of engineers, but they were drawn from many places and the best part was that when the war was over they went back to those many places. The Rad Lab designed radar but radar had the same elements as communications, and specifically digital communications. Thus from the Rad Lab came such innovations as the modem, designed by Jack Harrington, to interconnect signals from distributed sites. From the Rad Labs came rapidly effected engineering systems, and the terms system is critical, because the parts all worked together. From the Rad Labs came a set of book, the Rad Lab Series, which became the bible for engineers who entered the wireless world and the digital age. The Rad Lab was a petri dish that bred hundreds of engineers who went forth and created the core "startups" in the Cambridge 128 areas and also in Silicon Valley.DoD Design Companies: It is well known that many of the transistor companies were driven by the demands of DOD. Also many of these same types of companies in Silicon Valley and in the 128 Corridor were driven by DOD money as well. Groups of engineers educated from the Rad Lab type entities of WW II came out and started small companies fed from the DOD demands in those days. It allowed for many bright engineers to experience the "startup" albeit at the Government trough.This this book has strengths and weaknesses. Its strengths are:1. A well written story of some of the key players in Bell Labs.2. A well described evolution of the development of the management techniques.3. An excellent discussion of some of the major personalities in the R&D world at the time.Its weaknesses however should be considered when taking the author's conclusions to heart. Namely:1. This is truly a tale written from the perspective of Bell Labs. It totally fails to consider the competitors and thus when reaching his conclusion the author does so without any basis in fact. He totally ignores the weaknesses of such a system as Bell Labs and moreover he fails to consider the alternative entities such as the Rad Lab and its offshoots. In my opinion this is the major failing of this book. It would have been much more credible and useful if the author had looked at Bell Labs in the context of the total environment; the strengths and weaknesses and the competitors and alternative models of research.2. The monopolistic structure of AT&T was a major driver for what people do and why. The issue of return on investment being the profit, and not revenue less expenses, is a true distortion of what is done and why. This idea of a world view is a formidable force. It molded what the Labs and AT&T did and why they did it. The author seems to be totally devoid of any notion of its import.3. There were many failures at Bell Labs, and those failures were never truly perceived by those within the system, and it was this blind spot that in my opinion also led to its downfall. The author missed a great opportunity to follow up on this. Instead we see all these Herculean minds making great successes and yet the system collapses.4. Bell Labs was enormous in size and scope at its high point. I had spent time at Holmdel, Whippany, Indian Hill, Andover and even a brief stint at the remains of West Street. Yet the focus is on Murray Hill and a small part of a small part. This is especially disturbing in light of the author's global conclusion which is reached without a single discussion of these areas. To do Bell Labs justice one must perforce covers these as well. The Pierce, Shockley and Shannon tales are told again and again, but the efforts of the hundreds of thousands of others over the decades are still silent. In the presentation by the author before a mostly former Ball Labs group it was clear that my observation on this point had substantial merit.Overall there is a significant story to be told but this author does not accomplish it. In fact the author's statement denigrating the entrepreneur and the process of "creative destruction" is made without any attempt to understand the difference between a monopolistic structure and competitive markets. Perhaps if we had kept the old paradigm we would still have our black rotary dial phones.
Jon Gertner’s “The Idea Factory†is a mild corrective to the commonly found anguished certainty that America’s days of innovative scientific greatness are behind us. In its exploration of the might and works of Bell Labs, this book reminds us that genius requires the right cultural environment to flourish, and it addresses whether collective or individual genius is the mainspring of scientific advancement. Ultimately, Gertner’s account gives the obvious answer—scientific advancement stands on a three-legged stool, dependent on all of the broader culture, muscular group effort, and heroic individuals. Ayn Rand would not agree, but then, what did she ever actually accomplish?Today’s AT&T is the successor to the business created by Alexander Graham Bell in 1882. Before its breakup in the 1970s, the entire web of companies under the AT&T umbrella was called the “Bell System.†It included various regional telephone companies, later called the “Baby Bellsâ€; Western Electric, which manufactured telephone related equipment; and, crucially for this book and for AT&T, Bell Telephone Laboratories, officially created in 1925. Being a monopoly always offered both benefits and problems for AT&T—from early on, the company had an intermittently uneasy relationship with sectors of the federal government that opposed its monopolistic power and deemed it a threat to both competition and broader society. For the most part, though, AT&T blunted these attacks with a strategy that emphasized cheaper and better customer service over time, which required continuously advancing the frontier of technology (thus the creation of Bell Labs); the free distribution of intellectual property; and a very close relationship with the government during World War II and the Cold War.The early years of Bell Labs were driven by Mervin Kelly, who spent his entire career there, from 1918, until becoming Director from 1951 through 1959. Kelly was responsible for much of the hiring and structure that made the efflorescence of Bell Labs possible. Although he was himself a vacuum tube expert, his real genius was organization. The goal of his organizational work was to ensure the overall success of AT&T—to improve the “system†until it was “universal, economic and efficient.†Today we are used to both universal service and to a wide smorgasbord of other cheap and excellent communication methods, but offering low-cost, good, universal telephone service was a radical goal in the early 20th Century. Kelly was fully aware of the magnitude of the task, but also had little doubt that AT&T could achieve it.Because Bell Labs was designed to advance the goals of the telephone system, all scientific work was ultimately done to address specific operational needs. At the same time, scientific work was encouraged that might not solve an operational problem immediately, or succeed at all, as long as it had, or might offer, some promise of relevancy to the overall goal of the system. Naturally, fixing one operational problem often not only improved service, but created, or revealed, another operational problem, the solution for which might involve an entirely new and different line of thinking, continuing the need to make advancements. Kelly viewed this practical need driving scientific research as a huge advantage—his men, as Gertner says, “had the great advantage of working to improve a system where there were always problems, always needs.†Unlike today’s tech magnates, Kelly’s goal was not to “break things†or “disrupt†existing structures, and it most definitely was not to enrich himself or those who worked with him (although he did well enough to have a nice house). This was a more public-spirited time with a much more collectivist, in the good way, ethos.Among Kelly’s hires were Jim Fisk (instrumental in the development of radar and Kelly’s successor as Director of Bell Labs); William Shockley, Walter Brattain, and John Bardeen (the driving forces behind the invention of the transistor—Bardeen is the only person to have received two Nobel Prizes in physics); and Claude Shannon. Shannon was the developer of modern information theory, an utterly original set of ideas, including the reduction of communication “noise†through checksums, and also the author of a crucial 1945 mathematical treatise on cryptography. He additionally created a wide range of silly-yet-impressive inventions, including a calculator using Roman numerals, named THROBAC, which gives you a flavor of the Bell Labs environment. Through the 1920s and 1930s Kelly hired the best men, by offering both high salaries and prestige, moved them to New York, and put them in an environment of creative ferment. All Bell Labs scientific work was focused on experiment, but over time, as technology evolved, the tinkering aspects, such as endless methodical experiments to determine the best methods for cable sheathing, were supplemented by more theoretical physics, such as Shockley’s research and writing a classic work, “Electrons and Holes in Semiconductorsâ€, exploring the physics of solid state materials.Kelly also oversaw the move of Bell Labs from its original crammed offices in New York City to much larger quarters at Murray Hill in New Jersey. For both Kelly and Fisk, physical proximity of people was key. The New York offices provided such proximity by stuffing everyone in one building, but the new Murray Hill building was deliberately designed for collaboration. Office and lab space could be shrunk or expanded with movable walls. Kelly forbade any scientist to close his door and required that even the most senior be willing at any time to entertain walk-in questions from others. Men working together had their labs and offices separated, so that they constantly had to walk a long way down the corridors, bumping into people and having unplanned, fruitful conversations. Throwing together scientists working in disparate technical areas ultimately proved critically important to the success of Bell Labs, in ways great and small. For example, Shockley worked in close physical proximity to several scientists whose focus was the apparently unrelated area of creating ultra-pure elements of various types, work that proved critical to the creation of the transistor, both for its physical material and for understanding the theoretical underpinnings of semiconductors. (I suppose this creative ferment is what the modern fad for open office layouts is supposed to accomplish, but I suspect that you have to have geniuses working for your company—otherwise, you just have created inefficiency and wasted time.)Gertner covers the origin of Bell Labs and the war years; then he spends quite a bit of time on what is almost certainly the most important invention generated by Bell Labs, the transistor. Kelly and Fisk immediately realized the economic importance of the transistor, even though they could not foresee its ultimate role in modern society. Their focus was improving their system; transistors could replace vacuum tubes (and other devices, too), but were vastly cheaper and better. But they also saw that the transistor would have many additional applications, and they knew that many of those applications were not visible to them. AT&T’s ownership of Western Electric allowed the company to move transistors to mass production rapidly (a running theme of the book is the handoff of pure science to AT&T’s development/manufacturing teams, which got less glory but were necessary to every success of Bell Labs). Critically, even before the transistor was perfected, Bell Labs shipped samples for experimental use to any scientist who asked, and ultimately shared the intellectual property with the entire world (both on principle and to insulate themselves from attack as a monopoly). Gertner also covers other postwar work, from development of the Nike anti-missile system, to solar cells (which only came into wide use after the decline of Bell Labs), to fiber optics, which were critical to the ultimate development of the perfected telephone system, though the materials science mostly came from Corning. (Fiber optics helped underwater transmission, although transatlantic cables were first, amazingly, done with copper, using vacuum tubes as the amplifiers/repeaters.) Failures such as the Picturephone, a classic example of groupthink, also get their due. And, finally, Gertner covers the forced breakup of AT&T and the demise, for all practical purposes, of Bell Labs (although it still exists, legally, now as a subsidiary of Nokia). Probably its demise was inevitable, both because times changes, and because its guiding principal, improvement of the system, both was largely achieved and its importance largely eroded by other methods of communication.Almost all of the men profiled in this book (and they are all men) came from small town America, flyover country, with parents who were farmers, clerks, and housewives. Mervin Kelly came from Gallatin, Missouri; his father ran a hardware store. Claude Shannon came from Gaylord, Michigan; his father was a probate court judge. Brattain came from rural Washington State. Shockley came from Palo Alto—long before Palo Alto is what it is today. Thornton Fry, Bell Labs’s mathematical genius, came from Findlay, Ohio, the son of a poor carpenter. John Pierce (instrumental in satellite communication and the mind behind Echo, a huge metallized balloon in low-earth orbit used to test satellite communications concepts) grew up in Iowa. Yet these men became the giants that shaped the modern world. While many toiled in obscurity, many were widely recognized as geniuses at the time, both by the scientific community and by the popular media—more than one appeared on the cover of Time.This ascension of small-town Americans to positions of national prominence based on their intellect seems, at least in my impression, to happen much less nowadays. Why? First, I suspect the structures for identifying and elevating the promising in early and mid-20th Century America were better. As with the medieval church, local teachers could identify the promising, recommend them to others up the chain, and make it possible for them to both receive an education commensurate with their talents and find appropriate employment. Nobody, then, talked about “privilege,†believed in leveling egalitarianism, or wasted time on educational topics of no social value, such as Latino studies or the fantasy that the Constitution is at all based on the governance of the Iroquois Confederacy (something my eighth-grader today told me was being taught to him at his very expensive, and not progressive, school, an idea roughly equivalent to believing that the Sun is an egg for a monstrous alien). Instead, both teachers and students focused on advancement. For example, Cal Fuller, a Bell Labs chemist critical to semiconductor development, came from a poor family in Chicago. But his high school physics teacher knew that “the University of Chicago offered exams to high school students in science and math. She also knew that for those who passed, the university provided full tuition for the first year and, if you were among the top twenty-five students in your class at the university, for the following three years.†So she tutored Fuller nights for free and insisted Fuller pursue the scholarship, which he did, then going to graduate school “by working the four-o’clock-to-midnight shift at the ‘Chicago Tribune’.†With today’s teachers torn between shrill demands to use gender-inclusive pronouns and to teach what’s going to be on the next dumb federally mandated test, this sort of thing must happen much less today.Second, to the extent the intelligent and capable are identified, they rarely focus on the hard sciences. They are skimmed off into fields requiring far less hard training and offering far greater monetary rewards, yet which are largely destroyers of social capital, notably finance and law. Water flows on the path of least resistance, and why should our talented young be any different? Third, top colleges are now dominated by the children of our elite, who tend to marry each other much more than in the past, live on the coasts, and send their children to the same top colleges. They do this not so much to get an education as to get a credential that will allow them to pass the necessary filters and get jobs maintaining their position in the elite—which, for the most part, does not include those with jobs in hard science. In the hard sciences, therefore, most students today are Chinese or Indian, who take their knowledge home and advance their societies. For all these reasons (and perhaps others), even though our population is larger today, we appear to have fewer home-grown geniuses, and they are less prominent. Whether that means less absolute scientific advancement is less clear—maybe scientific breakthroughs are less obvious to the average person than they were decades ago, because earlier advances have made today’s advances more specialized and harder for the layman to understand. I suspect that if we had the old system we’d have a lot more advancement, though.Bell Labs scientists not only worked closely together; they frequently socialized together, although many had odd, difficult or intensely private personalities that made such socializing probably less than glittering. Their work efforts were, as Gertner says, “group efforts, a compilation of the ideas and inventions of individuals bound together with common purposes and complementary talents.†It could not really be otherwise, given that their overall goal was improving the telephone system. But at root, all critical breakthroughs were individual breakthroughs—as Kelly said, “With all the needed emphasis on leadership, organization and teamwork, the individual has remained supreme—of paramount importance. It is in the mind of a single person that creative ideas and concepts are born.†Surrounding all this, of course, was a forward-looking, optimistic America, focused on individual and societal progress without a morbid fear of risk or cost. Viewing old “Twilight Zone†episodes, for example, will give you a sense of how America thought, and it is very different than the way America thinks today. It was the combination of these things—group effort, individual effort, and the national culture—that enabled the achievements of Bell Labs.Gertner ends with an excellent question. “Regrettably, the language that describes innovations often fails to distinguish between an innovative consumer product and an innovation that represents a leap in human knowledge and a new foundation for industry. . . . [A]re we will living off the dividends from ideas that were nurtured, and risks that were taken, a half century ago?†Probably the answer is “yes.†I think that the existence and accomplishments of Bell Labs are in many ways a reproach to the extreme libertarian model that has taken hold of much of United States industry today. You don’t have to be a syndicalist or a Chestertonian Distributist to see that a model of close cooperation between a technology-focused company and the government, with the scientific results shared with all other comers for a nominal fee, rather than locked up by patents and legions of lawyers, accompanied by an ethos of public benefit (and lacking the parasitism of the “diversity and inclusion†crowd), is in many ways superior to the social utility-reducing quest for monopoly beloved by such men as Peter Thiel. It is not the case that everything that is not purely libertarian is crony capitalist. In fact, much of what is proudly libertarian is actually totally crony capitalist (see, e.g., Musk, Elon). Of course, the glory days of Bell Labs was a unique time, with easier, cheaper breakthroughs; a completely different government and ruling class; and World War II and the threat of global Communism—but then, every time is unique. Maybe, or probably, the exact same setup wouldn’t yield the same dividends today, but this book still has important lessons for us, among them that a search for a system that *will* yield such dividends is very worthwhile.
I absolutely loved this book. I was in telecommunications for over 10 years contacting for GTE at Sandia Laboratories - (once managed by an arm of Western Electric and Bell Labs) and I managed a Lucent / AT&T 5ESS. Reading about all of this made me feel nostalgic and a little sad. Technology has moved so fast, that it seems the old equipment, technicians and Switch engineers have been replaced by machines and forgotten. My company, GTE merged with a baby bell, Bell Atlantic and became Verizon. I just somehow feel connected to all of these great inventors who started my career path right out of high school. My first training was at a lab in Atlanta, GA called Lucent technologies and I learned how fiber was made, and was certified to pull, splice and install fiber. I eventually worked my way up from the manholes into the switch, then accepted a job running networks for Kirkland AFB. The progression in communications is always spiraling upward and gave a person like myself a career with no ceiling. I am grateful for their tireless efforts and labors and feel indebted to their genius. I am in awe of the brilliance of these men and women and I absolutely loved the book. A trip down memory lane for me!! Thank you!
