My question had to be narrower, more rooted in time and place. It was about the object. “Not ideas about the thing but the thing itself,” as Wallace Stevens wrote. Not, where did the Internet begin? But, where was its first box? And that, at least, was clear. In the summer of 1969, a machine called an interface message processor, or IMP, was installed at the University of California–Los Angeles, under the supervision of a young professor named Leonard Kleinrock. He’s still there, a little less young, but with a boyish smile and a website that seemed to encourage visitors. “You’ll want to meet me in my office,” he replied when I emailed. “The original site of the IMP is just down the hall.” We made arrangements. But it wasn’t until I settled into my cramped seat on the plane to Los Angeles, surrounded by tired consultants in wrinkled shirts and aspiring starlets in sunglasses, that the full implications of my journey sank in: I was going to visit the Internet, flying three thousand miles on a pilgrimage to a half-imagined place.

The excitement of the occasion would have been unmistakable, even if the full historic implications were not: this was the first piece of the Internet. But while the grad students were celebrating outside, their professor was stuck upstairs, alone in the large office he had recently expanded in a fit of empire building, shuffling papers on a Saturday afternoon. This I can picture precisely, because when I walked in forty-one years later, Leonard Kleinrock was still sitting there, sprightly at seventy-five, wearing a starched pink shirt, black slacks, and a BlackBerry clipped to a polished leather belt. His face was tanned and his hair was full. A brand-new laptop was open on his desk and he was yelling into a speakerphone: “It’s not catching!” On the other end, the disembodied voice of a tech support person responded slowly and patiently. Click here.

They came up with the answer down the road, in the heart of Silicon Valley—in a basement, in fact. Only Connect For a couple of years at the beginning of the millennium—during the quiet time after the Internet bubble burst but before it inflated again—I lived in Menlo Park, California, a supremely tidy suburb in the heart of Silicon Valley. Menlo Park is a place rich in a lot of things, Internet history among them. When Leonard Kleinrock recorded his first “host-to-host” communication—what he likes to call “the first breath of the Internet’s life”—the computer on the other end of the line was at the Stanford Research Institute, barely a mile from our apartment. A few blocks past there is the garage where Larry Page and Sergey Brin first housed Google, before they moved into real offices above a Persian rug store in nearby Palo Alto.

In 2010, I was in Israel as a guest speaker at the Dan David Prize ceremony in Tel Aviv. Every year, the Dan David Foundation and Tel Aviv University give out prizes that “recognize and encourage innovative and interdisciplinary research that cuts across traditional boundaries and paradigms.” Leonard Kleinrock of UCLA was there to receive in the category of “The Future—Computers and Telecommunications.” As a slideshow presented the audience with a summary of Kleinrock’s achievements, I excitedly whispered to my wife, Dasha, “That’s him! That’s the guy who sent the ‘l’ and the ‘o’!” On October 29, 1969, Leonard Kleinrock’s lab sent the very first letters over ARPANET from his computer at UCLA to another machine at Stanford. They attempted to send the word “login” but the system crashed after the first two letters had gone through. A month later, a permanent link between the machines was in place.

Then the 1973 Mansfield Amendment limited DARPA appropriations to projects with direct military application, a heavy blow to government support of basic research in the sciences and a death blow to relatively unproductive fields like AI was turning out to be, at least in the eyes of the Defense Department. They wanted expert systems for recognizing bomb targets, not machines that could talk. Leonard Kleinrock was still at UCLA, but he turned out to be our neighbor on the Upper West Side of Manhattan. He was gracious enough to share with me some of his thoughts on why and how ARPA (as he always insisted on calling it) fell from grace as an engine for AI and other tech innovation. His first conclusion was not surprising: the growing government bureaucracy stifled communication and innovation. “It got big,” he told me over lunch.

The era when giant multinational companies like Bell and government programs like DARPA would pour money into basic research and experimental projects is over. R&D budgets have been slashed over the years as investors take a skeptical view of anything that doesn’t feed the bottom line. Government-backed research tends to favor specific gadgets to fit an existing need, not ambitious, open-ended missions to answer big questions like Leonard Kleinrock’s “How do we get every computer in the world to talk to each other?” The Oxford Martin School at Oxford University has collected quite a few of these exceptional people, and also encourages the sort of interdisciplinary associating and free-associating that has gone out of fashion in this era of specialization, benchmarks, and ninety-page grant applications. As a senior visiting fellow there since 2013, I’ve had the privilege to meet many of these brilliant people, including Nick Bostrom, the author of Superintelligence, and other faculty and researchers at his Future of Humanity Institute.

Phone calls use what’s called “circuit switching”: the system opens a channel between the sender and the receiver, which supplies constant bandwidth between the parties in both directions as long as the call lasts. Circuit switching makes plenty of sense for human interaction, but as early as the 1960s it was clear that this paradigm wasn’t going to work for machine communications. As UCLA’s Leonard Kleinrock recalls, I knew that computers, when they talk, they don’t talk the way I am now—continuously. They go blast! and they’re quiet for a while. A little while later, they suddenly come up and blast again. And you can’t afford to dedicate a communications connection to something which is almost never talking, but when it wants to talk it wants immediate access. So we had to not use the telephone network, which was designed for continuous talking—the circuit switching network—but something else.

In response, the Advanced Research Projects Agency was created (so was NASA) and, tellingly, located inside the Department of Defense. One of the issues of the day was the idea that a nuclear blast (I’ve learned never to trust anyone that pronounces it nu-cu-ler) would wipe out the phone network and all communications lines and disable the command and control structure of U.S. defense. The president could order a launch, but if no one could get the message, what would be the use? In 1961, Leonard Kleinrock at MIT proposed a PhD thesis called “Information Flow in Large Communication Nets,” and this provided the theory and proof for packet switching, although it wasn’t called packet switching, not yet, and it was still a theory. The North American Aerospace Defense Command or NORAD was in charge of early warning and control. It didn’t want no stinking 144 HOW WE GOT HERE theories, it wanted something it could use.

In September of 1969, an IMP was set up at UCLA and in October, another was set up at Engelbart’s office in the Stanford Research Institute. They were connected by a 50-kilobit per second connection that AT&T provided. One can imagine that AT&T was not at all enthusiastic about the project, since packet switching endangered the phone network. But there was probably pressure to act patriotically - plus the government paid good money. Leonard Kleinrock, the MIT theorizer, of course joined the ARPANET project, since it was his theory being implemented. I sat next to him at a dinner in 2000, and he gladly recounted the story: He was at UCLA and on the phone to Stanford. “OK, we are about to send an ‘L’, let me know when you see it,” Kleinrock told the Stanford folks. “There it is, we got an ‘L’, (sound of applause in the background)” “OK, OK, just a second, hold on, we are going to send an ‘O’.”

Hush-a-Phone Corp. v. United States, 238 F. 2d 266 (D.C. Cir., 1956). 20 The idea is developed in Kleinrock's dissertation: Leonard Kleinrock, Message Delay in Communication Nets with Storage (1962, unpublished Ph.D. dissertation, Massachusetts Institute of Technology), which was later published in a modified form. See Leonard Kleinrock, Communication Nets: Stochastic Message Flow and Delay (New York: McGraw-Hill, 1964). See also John Naughton, A Brief History of the Future: The Origins of the Internet (London: Weidenfeld & Nicolson, 1999), 92, 118-19 (discussing other earlier contributors to the Internet). 21 Baran attributes to him the discovery of the term.

If you digitized a conversation—translating it from waves to bits—and then chopped the resulting stream into packets, these packets could flow independently across a network and create the impression of a real-time connection on the other end. As long as they flowed fast enough, and the computers at both ends were quick, the conversation encoded in this packet form would seem just like a conversation along a single virtual wire across the ocean. Baran was probably not the first person to come up with this idea—MIT loyalists insist that that was Leonard Kleinrock.20 And he was also not the only person working on the idea in the early 1960s. Independently, in England, Donald Davies was developing something very similar.21 But whether the first, or the only, doesn't really matter for our purposes here. What is important is that Baran outlined a telecommunications system fundamentally different from the dominant design, and that different telecommunications system would have effected a radically different evolution of telecommunications.

It was lunchtime at George Gilder’s Telecosm conference, and we were waiting for the featured speaker, Gary Winnick of Global Crossing, to explain how he sends billions of packets per second under the Atlantic Ocean. George Gilder has hosted his Telecosm conference for years. Tech luminaries like Carver Mead, Bob Metcalfe and Paul Allen were regulars. “I don’t know what the first packet was,” I confessed. My tablemate turned out to be Leonard Kleinrock, a UCLA professor, according to his name tag. It turned out that he had been at the creation. Since the 1978 introduction of the Apple II computer, to the 1981 announcement of the IBM PC, the world has been flooded with smaller, cheaper and faster computers. More than 100 million new ones get sold every year. But today, these are no islands—the power of these computers is in their ability to communicate.

The telephone network, which is optimized for your talks with 184 Running Money Mom, was the medium for computer communications. No one thought this out; it just happened that phone lines were running everywhere, so as computers were placed in the same everywhere, they used the phone network to communicate. The problem is that from the very beginning, the phone network cut corners. Fortunately, the Cold War gave us packets. “It was the fall of 1969,” Leonard Kleinrock started. I think I was watching The Munsters back then. “We had the first IMP from BBN. I think it cost ARPA around $10,000. Which doesn’t seem like much until you remember that a Volkswagen Beetle cost $2000.” “We?” I asked. “Oh, sorry, UCLA.” “Was Lew Alcindor involved in all of this?” “Who?” “Never mind. Could you translate the acronyms?” “So anyway, this Interface Message Processor was a modified Honeywell 516 minicomputer.

For those of you who were not tech-savvy in the early days of the Internet, the difference between the public Internet and an online service were profound. The Internet The public Internet was first proposed by J.C.R. Licklider of MIT in the early 1960s. It was conceived as a global network of computers to allow the sharing of scientific and military research. The project was conscripted by the Defense Advanced Research Project Agency (DARPA) in late 1962 and through the work of several now legendary scientists, like Lawrence Roberts, Leonard Kleinrock and Bob Kahn, evolved into the global network of computers it is today. That network, now called the Internet (or simply, the Net) is the transport system that packets of data travel over. Your e-mail, music and video files all live on individual storage devices (like the hard drive in your computer) and get from place to place over the public Internet. This is not to be confused with the World Wide Web.

Vint Cerf: old school, meticulous, playful – and smart as hell. I’m hoping Vint can give me the big picture on our increasing interconnectedness. After all, he was in at the ground floor of the Internet and now works on the top one. He’s a man with a career-length view on the technology, which for a technology as young as the Net is about the longest view you can have. As a graduate student, Cerf worked under Professor Leonard Kleinrock, who in 1969 oversaw the first computer-to-computer message to be sent using the ‘packet switching’ method that underlies the Internet. Actually, it was two-thirds of a message. Another of Kleinrock’s students, Charley Kline, hoped to send a three-letter message ‘LOG’ to a receiving machine (this being the code for logging on to that computer). The ‘L’ and the ‘O’ worked but the ‘G’ crashed the system.

Technological protocols and cultural pipedreams aligned and collided. The drug and music countercultures and the early technological innovators informed and inspired each other – and were often the very same people. The acronymic utopias enabled by internet technologies such as TCP/IP aren’t so different from those offered by LSD: equality, connectedness, awareness of life as a sum greater than its parts. In the early 1960s, American computer scientist Leonard Kleinrock of the Massachusetts Institute of Technology and Paul Baran of the Rand Corporation, and, later, Britain’s Donald Davies, a physician at the UK’s National Physical Library in Teddington, independently conceived of the same way to send data around a telephone network efficiently by splitting it into chunks and routing it through nodes around the network to later arrive, reassembled, in the right place.

It was the evening of October 29, 1969, and Charley Kline, a twenty-one-year-old student at the University of California, Los Angeles, was working late in the computer lab. UCLA had an SDS Sigma 7 computer, a mainframe that filled an entire room. Several people sitting at separate terminals could use this giant computer at the same time, and Kline could be found writing code on it at all hours of the day and night. That evening Leonard Kleinrock, the professor in charge of the computer lab, asked Kline to help him test a new device that would link the Sigma 7 to another computer at the Stanford Research Institute, four hundred miles away in Menlo Park, California. The project to link computers in this way had begun when Bob Taylor, an official at the Advanced Research Projects Agency (ARPA), the research arm of the U.S. Department of Defense, became frustrated by the proliferation of computer terminals in his office.

Bringing together two different computers was one thing, but the project for which Roberts had been pulled away from Lincoln to work at ARPA was another, much greater challenge. Interconnecting a matrix of machines, each with distinct characteristics, would be exceedingly complicated. To pull it off was probably going to require calling on every expert Roberts knew in every area of computing and communications. Fortunately, Roberts’s circle of colleagues was wide. One of his best friends from Lincoln Laboratory, with whom he had worked on the TX-2, was Leonard Kleinrock, a smart and ambitious engineer who had attended MIT on a full scholarship. If anyone influenced Roberts in his earliest thinking about computer networks, it was Kleinrock. Kleinrock’s dissertation, proposed as early as 1959, was an important theoretical work that described a series of analytical models of communication networks. And in 1961, while working with Roberts, Kleinrock had published a report at MIT that analyzed the problem of data flow in networks.

This process would be repeated until all the incoming packets were deemed acceptable, at which point the receiving computer would string them together and reconstruct the original message. Complicated? Perhaps, said Roberts. But the basic techniques were well un- derstood; people had been segmenting the data on tape drives and other error- prone media for more than a decade. And more to the point, the use of packets in networking had been thoroughly analyzed in the 1962 Ph.D. thesis of Roberts's MIT classmate Leonard Kleinrock/- who was now at UCLA. He and Kleinrock had discussed the issues extensively when he was planning the 1 965 experiment, Roberts said. And the experiment itself had proved that the packet idea would work: the packets arriving on the other side had been reconstructed quite well. Now, those first two conclusions were comparatively straightforward, said Roberts. Taken together, however, they led to a third issue that was not straightfor- ward at all: routing, or getting the data packets where they were supposed to go.

After the initial stages of planning, most of the collaborative effort was taken on by the Network Working Group (NWG), a more formal reorganization of the informal committees of contractors decided by Larry Roberts (Norberg and O'Neill 1996, 167). In fact, Roberts organized the network implementation around three different teams with various contracts and links between them: the NWG itself; 6 Leonard Kleinrock and his team of graduate students (in- cluding Steve Crocker, Vint Cerf, and Jon Postel) at UCLA, which was to be- ARPANET, E-matl, and est 185 come the Network Measurement Center (NMC); and finally, Douglas Engel- bart and his staff, which was to become the Network Information Center (NIC). Early in the history of the NWG, Elmer Shapiro insisted that "the work of the group should be fully documented."

Behind the development of the Internet there was the scientific, institutional, and personal networks cutting across the Defense Department, National Science Foundation, major research universities (particularly MIT, UCLA, Stanford, University of Southern California, Harvard, University of California at Santa Barbara, and University of California at Berkeley), and specialized technological think-tanks, such as MIT’s Lincoln Laboratory, SRI (formerly Stanford Research Institute), Palo Alto Research Corporation (funded by Xerox), ATT’s Bell Laboratories, Rand Corporation, and BBN (Bolt, Beranek & Newman). Key technological players in the 1960s–1970s were, among others, J. C. R. Licklider, Paul Baran, Douglas Engelbart (the inventor of the mouse), Robert Taylor, Ivan Sutherland, Lawrence Roberts, Alex McKenzie, Robert Kahn, Alan Kay, Robert Thomas, Robert Metcalfe, and a brilliant computer science theoretician Leonard Kleinrock, and his cohort of outstanding graduate students at UCLA, who would become some of the key minds behind the design and development of the Internet: Vinton Cerf, Stephen Crocker, Jon Postel, among others. Many of these computer scientists moved back and forth between these various institutions, creating a networked milieu of innovation whose dynamics and goals became largely autonomous from the specific purposes of military strategy or supercomputing linkups.
