The Rad Lab and the Birth of the Innovation Economy
The story of Boston as a technology capital begins with a single institution: the MIT Radiation Laboratory (the “Rad Lab”). Established in October 1940, fourteen months before the United States entered World War II, the Rad Lab became the largest cooperative research establishment in history.1 At its peak it employed nearly 4,000 people, spent $4 million per month, and designed half of all radar deployed by the U.S. military during the war. The laboratory received $106.8 million ($1.91 billion in 2025) in government contracts, comprising 23% of all Office of Scientific Research and Development spending. Equipment of Rad Lab design accounted for $1.3 billion in radar production (approximately $23 billion in 2025).
This was a firehose of federal capital pointed directly at a single metropolitan area’s research institutions, with explicit instructions to commercialize the output. In addition to radar production, the Rad Lab produced the institutional architecture that would define Boston’s economy for the next half century, including the relationships between universities, defense contractors, and government funders.
When the Rad Lab closed on December 31, 1945, its functions dispersed into MIT’s Research Laboratory of Electronics and, in 1951, Lincoln Laboratory, which was established to develop air defense systems. Lincoln grew rapidly to 2,000 staff and a $20 million annual budget.2 Its first major project, the Semi-Automatic Ground Environment (SAGE) air defense network, became the largest military research and development (R&D) enterprise since the Manhattan Project, which cost $8 billion. By 1946-47, MIT’s research budget of $8.3 million dwarfed its academic budget of $4.7 million.3 The university had been fundamentally transformed into a defense research engine, and the surrounding economy transformed with it.
Georges Doriot and the Birth of Venture Capital
The defense money pouring through MIT created the research output. But converting that research into companies required a financial instrument that did not yet exist. The man who created it was a French-born Harvard Business School professor named Georges Doriot, and the institution he built was the American Research and Development Corporation (“ARD”), founded in Boston in 1946.4
ARD was the first modern venture capital firm, the first to raise capital from institutional investors rather than wealthy families. Its founding coalition reads like a roster of Boston’s institutional power: Karl Compton, president of MIT; Ralph Flanders, president of the Federal Reserve Bank of Boston (later a U.S. Senator from Vermont); Donald K. David, dean of Harvard Business School; and Merrill Griswold, head of Massachusetts Investors Trust. This was a group of institutional leaders who recognized that New England’s postwar prosperity depended on channeling capital into new industries.
ARD’s most consequential investment was its 1957 backing of Digital Equipment Corporation (“DEC”), founded by Kenneth Olsen, an MIT researcher who had worked at Lincoln Laboratory. ARD invested $70,000 for a 70% stake. By 1971, that stake was worth $355 million.5 DEC became the largest employer in Massachusetts and the second-largest computer manufacturer in the United States. A single investment, made possible by a financial institution created specifically to commercialize the research coming out of the defense-university pipeline, catalyzed the entire minicomputer industry and anchored Route 128 as a global technology corridor.
Doriot believed that capital’s purpose was not speculation but creation. He invested in founders, not ideas. He held investment positions for a decade or more, referring to portfolio companies as his children. And he did all of this from Boston, in a firm whose investments were overwhelmingly local, generating what a Commerce Department study in 1967 ranked as the highest concentration of technology-based companies of any American city.
The lesson is often missed: Boston had an institutional mechanism, funded by the same network of university and civic leaders who oversaw the defense pipeline, that converted research into companies and kept those companies local.
Doriot believed that capital’s purpose was not speculation but creation. He invested in founders, not ideas.
And then Boston lost it. ARD was structured as a publicly traded closed-end fund, subject to Securities and Exchange Commission (SEC) regulations that prohibited the stock options and carried interest that would later become standard in venture capital. Doriot’s investment officers could not participate in the upside of the companies they backed, and the best of them left. Arthur Rock, who had trained under Doriot at Harvard, moved to San Francisco and financed Fairchild Semiconductor and Intel. Thomas Perkins, one of Doriot’s top students, declined to succeed him at ARD because, as he later admitted, there was no way to make significant money under ARD’s structure. He co-founded Kleiner Perkins in Menlo Park instead. Thomas Davis founded the Mayfield Fund on the West Coast. One by one, the people who had learned the venture capital business in Boston rebuilt it in California using the limited partnership model, which let them capture 20% of investment gains. The financial architecture of Sand Hill Road was designed in Cambridge and exported to Palo Alto.
When ARD merged with Textron in 1972, the first chapter of Boston’s venture capital industry effectively closed. The center of gravity had already shifted. By the time the minicomputer boom made Route 128 famous, the financial infrastructure that would fund the next generation of technology companies was being built three thousand miles away.

Route 128: Capital Creates Density
The ecosystem that emerged around Route 128 was not organic. It was the direct product of concentrated federal spending flowing through MIT and Harvard into a cluster of defense contractors, electronics firms, and eventually computing companies. By 1958, 99 firms and 17,000 workers were located along Route 128. By 1972, there were 1,212 firms.6
This is the dynamic that people describe when they talk about Silicon Valley’s density, where every corner is a meeting place for entrepreneurs, investors, and talent. They are right about what it looks like, but they are wrong about how it is created. That density did not emerge from a brand or a program; it emerged from a sustained pipeline of capital so large that it reshaped the physical geography of a region. Defense money flowed into MIT. MIT produced researchers. Researchers spun out companies. Doriot and ARD funded them. Companies clustered near the university and near each other. Additional venture capital formed to fund them. This entire system became self-reinforcing.
The mechanism was straightforward: the federal government provided a massive, steady customer (the Department of Defense) whose contracts funded R&D, absorbed cost-plus pricing, and created a guaranteed market for the output. This was innovation with a buyer standing at the end of the pipeline with an open checkbook.
The Shipyard, the Factory, and What Was Lost
The capital pipeline did not only build high-tech labs. It built an entire industrial base. The Fore River Shipyard in Quincy, founded in 1883, became one of the largest shipbuilding facilities on the East Coast. At its peak during World War II, the Shipyard employed 32,000 workers and built 92 naval vessels, including battleships, aircraft carriers, cruisers, and destroyers, more destroyers than any shipyard in the country.7 Joseph Kennedy worked there. “Kilroy Was Here” may have originated there. The Shipyard was Quincy’s economic identity for a century.
General Dynamics closed Fore River in 1986 after failing to win a major contract since 1982, eliminating 4,200 jobs.8 The closure was part of a national collapse: since 1981, 25 of the country’s 110 shipyards had closed, shedding 20,000 jobs. For Quincy, this was existential. The Shipyard was not just a workplace; it was a pipeline that trained welders, electricians, engineers, and managers, a workforce development engine embedded in the community. When it closed, the skills pipeline closed with it.
This pattern repeated across Massachusetts. The state’s manufacturing base, built on defense contracts, textiles, precision instruments, and heavy industry, hollowed out as contracts moved south and overseas. The story is usually told as a high-tech narrative: Route 128 rose, then Silicon Valley won. But the blue-collar version is equally important. Massachusetts lost not just minicomputer engineers to California but it lost shipbuilders to closure, machinists to obsolescence, and factory workers to global competition. The state’s working class lost its economic footing at the same time its knowledge economy began to wobble.
What Killed the Engine
The decline was mechanical. Between 1967 and 1972, defense contracts awarded to New England declined approximately 40% in real terms. Massachusetts lost 112,000 manufacturing jobs, 15% of them from high-tech firms.9 The 1973 recession and 1974 oil crisis compounded the damage. The pipeline that had been feeding the ecosystem for three decades was constricted at the source.
The minicomputer boom of the late 1970s and 1980s temporarily replaced defense spending as the growth engine, producing what politicians called the “Massachusetts Miracle.”10 But the miracle was built on a single industry cycle, not on durable infrastructure. When the personal computer (PC) revolution arrived and the minicomputer market collapsed, Route 128 had no fallback. DEC was acquired by Compaq in 1998, Wang filed for bankruptcy, and Data General was absorbed by EMC.
The deeper structural problem was cultural, and it ran deeper than corporate structure. Route 128 firms were vertically integrated, secretive (a legacy of defense contracting culture), geographically dispersed, and loyal to corporate hierarchy.11 Silicon Valley, by contrast, was dense, porous, and organized around networks rather than firms. Workers in the Valley job-hopped freely, shared information across company lines, and identified with the ecosystem rather than with any single employer.12 Stanford actively promoted startups and oriented its culture around commercialization and company-building; MIT, with deeper government ties and a stronger research tradition, was more cautious and academic. This institutional difference shaped everything downstream. Boston produced breakthrough research, patents, and deep technical knowledge. Silicon Valley produced companies. The difference was risk tolerance, which was shaped by the capital architecture that surrounded each ecosystem. The venture capitalists who had learned their trade at ARD in Boston were already building the financial infrastructure of the West Coast.
The result was a slow-motion transfer of gravity from east to west because Silicon Valley had a capital and cultural architecture that converted ideas into companies faster, retained the value locally, and recycled success into the next generation of ventures.
