Who Made Up The National Defense Advisory Commission

You're digging through a history book or maybe a Wikipedia rabbit hole, and a name pops up: the National Defense Advisory Commission. It sounds official. Important. Like something that should have a marble building and a Wikipedia page longer than your arm.

But then you ask the obvious question: Who actually sat around that table?*

The answer isn't a single name. Still, it's seven. And the story of how those seven people got there — and what they did once they arrived — tells you more about how America mobilized for World War II than most troop movement maps ever could.

What Was the National Defense Advisory Commission

Let's get the bureaucracy out of the way first. The NDAC wasn't a permanent agency. It wasn't a cabinet department. But it was an advisory body created by President Franklin D. Roosevelt on May 28, 1940, tucked inside the newly formed Office for Emergency Management (OEM).

The timing matters. May 1940. France was falling. Worth adding: dunkirk was happening. The U.Plus, s. Which means military was tiny — 18th in the world, behind Portugal — and the industrial base was still shaking off the Depression. That said, roosevelt knew war was coming. He also knew he couldn't just order Detroit to build tanks. In real terms, he needed industry to want* to build them. Now, he needed labor to agree* not to strike. He needed a bridge between Washington's urgency and the country's capacity. Worth keeping that in mind.

The NDAC was that bridge. Their job? Seven commissioners. On the flip side, one dollar a year men, as they called themselves. On top of that, each represented a slice of the American economy: industry, labor, agriculture, transportation, and so on. No salaries. Advise the President and the Council of National Defense on how to turn a peacetime economy into a war machine — without breaking the social contract. Turns out it matters.

It lasted about a year. By May 1941, it was absorbed into the Office of Production Management (OPM), and later the War Production Board (WPB). But in that year, it wrote the playbook.

The Seven Men at the Table

Roosevelt didn't pick technocrats. He picked power brokers. People who could pick up a phone and get things done in their respective worlds. Here's who they were.

William S. Knudsen — Industry (Automotive)

The big name. Plus, the Dane who started on a factory floor at Ford, helped build Chevrolet into a giant, and became president of General Motors in 1937. He was the only commissioner who got a formal title: Chairman.

Knudsen didn't want the job. He told Roosevelt he belonged in Detroit. His famous line: "We can build anything you want. Roosevelt told him the country needed him in Washington. Knudsen showed up in a rumpled suit, carrying his own briefcase, and immediately clashed with the military procurement officers who wanted detailed specs before placing orders. But you have to tell us what you want now.

He brought the language of mass production to a government that spoke in appropriations bills. In real terms, he's the one who convinced Detroit to retool for tanks and planes before* the contracts were signed. That gamble saved months.

Sidney Hillman — Labor

President of the Amalgamated Clothing Workers. A founder of the CIO. Roosevelt's closest labor advisor. Hillman was the counterweight to Knudsen — the guy who could walk into a union hall and get a no-strike pledge for defense work.

He wasn't popular with everyone. Southern Democrats hated him. But Hillman understood something crucial: if workers felt the war effort was just another way for bosses to roll back New Deal gains, production would stall. Think about it: the AFL hated him. Consider this: business leaders tolerated him only because Roosevelt insisted. He fought for maintenance of membership clauses, for fair wage boards, for the idea that labor had a seat at the table by right*, not by favor.

His presence on the NDAC was a political statement. It said: this isn't just industry's war.

Ralph Budd — Transportation

President of the Burlington Railroad. Budd knew the tracks, the rolling stock, the bottlenecks. A railroad man's railroad man. He also knew the Interstate Commerce Commission regulations that made flexible routing a nightmare.

His job was simple on paper: keep the freight moving. Consider this: in practice, it meant fighting the ICC, the Army, the Navy, and the maritime commission simultaneously — all of whom had different priority systems for the same boxcars. He built the Car Service Division, which effectively nationalized freight car allocation without ever saying the word "nationalized.

When the railroad crisis hit in late 1941 — congestion so bad that coal couldn't reach power plants — Budd had the relationships to force a solution. He didn't write memos. He called the other railroad presidents and told them what was going to happen.

Leon Henderson — Price Stabilization and Consumer Protection

An economist. Because of that, a New Dealer. On the flip side, the only academic type in the room. Henderson ran the price stabilization division, which meant he was the guy saying "no" to price hikes when raw materials got scarce.

He was unpopular. But he built the architecture of price control that the Office of Price Administration (OPA) would later scale nationwide. So naturally, congress investigated him. Industry thought he was a communist. Labor thought he was soft. Even so, really unpopular. He understood that inflation wasn't just an economic problem — it was a political time bomb. If soldiers' families couldn't afford rent and meat, the home front would crack.

He also hired a young woman named Margaret Chase Smith to help run the consumer division. She'd later become a Senator. Henderson spotted talent.

Edward R. Stettinius Jr. — Raw Materials

Chairman of U.S. Steel. Think about it: the only commissioner from heavy industry's old guard. Practically speaking, stettinius knew where the ore was, who owned the ships, and which Latin American dictators controlled the strategic minerals the U. Think about it: s. desperately needed — manganese, chrome, tungsten, rubber.

He built the Materials Division from scratch. But he negotiated the deals that brought Brazilian quartz, Chilean nitrate, and African cobalt into American factories. His solution: a mandatory allocation system backed by the full weight of the presidency. Because of that, he also fought the Army and Navy over who got priority for scarce alloys. It worked because Roosevelt backed him. Worth keeping that in mind.

Stettinius would later become Secretary of State. But his real legacy is the supply chain that didn't break.

Harriet Elliott — Consumer Interests

The only woman. Dean of Women at the Woman's College of the University of North Carolina. Day to day, a consumer advocate before that was a job description. On the flip side, she wasn't an industrialist or a union boss. She was there to remind the other six that housewives — the people managing ration books, victory gardens, and family budgets — were part of the production equation too.

She ran the Consumer Division. She organized the "Consumer Advisory Council," a network of women's groups, farm organizations, and labor auxiliaries that became the eyes and ears of the OPA on the ground. When meat shortages hit, her division explained why and how long* in language people trusted.

She's the one most histories forget. Don't.

Chester C. Davis — Agriculture

Former governor of the Farm Credit Administration. A Missouri farm boy who knew the New Deal's agricultural alphabet soup — AAA, REA, FSA — inside out. His job: keep the farms producing while millions of farm boys left for the Army.

He fought for deferments for essential farm workers. He negotiated the British wheat purchases that kept prices stable. In real terms, he pushed for the machinery allocations that let fewer hands harvest more acres. And he understood that rural America's support for the war wasn't automatic — it had to be earned, policy by policy.

Why This Group Mattered

Seven people. Different backgrounds. Different constituencies. Different egos.

They fought. Constantly. Knudsen thought Henderson was slowing production with

They fought. Constantly. Still, stettinius and Elliott clashed over whether consumer‑price controls should be tightened before or after raw‑material allocations were locked in, each fearing the other would choke either the factories or the households that depended on them. Also, knudsen thought Henderson’s insistence on “fair‑share” production quotas was a bureaucratic drag; Henderson saw Knudsen’s drive for raw‑material speed‑ups as a recipe for worker unrest. Davis, meanwhile, found himself the perpetual mediator, translating the language of farm‑gate economics into the jargon of steel mills and shipyards.

What kept them together was not personal chemistry but a shared, stark reality: without a coordinated conversion of the nation’s peacetime factories to a war‑time engine, the Allies would lose the strategic edge they had fought so hard to win. Worth adding: roosevelt’s confidence in these men was less about their titles and more about the fact that each brought a constituency that the others could not reach. Knudsen could order a plant to shift from car bodies to tank treads, but he needed Henderson’s labor‑relations savvy to keep the workforce compliant; Stettinius could lock down manganese shipments from Brazil, but he relied on Elliott’s consumer‑council to explain why a sugar ration was still in effect; Davis could keep a Missouri soybean field humming, but only if the Army’s truck fleet—built by Knudsen’s teams—kept rolling.

The system they forged was improvised, often chaotic, and at times outright contradictory, yet it delivered results that no single agency or cabinet member could have achieved alone. On top of that, by the summer of 1943, war production had surged past the 400‑million‑ton threshold, a figure that would have been impossible without the relentless data‑sharing, the mutually enforced allocation schedules, and the feedback loops that Elliott’s consumer panels fed back into the planning tables. The “big seven” turned a fragmented, competitive landscape into a quasi‑centralized command structure that resembled a wartime ministry more than a domestic agency.

When the war ended, the machinery they built did not simply dissolve. Worth adding: its DNA survived in the post‑war Office of Price Administration, in the Federal Highway Administration’s early road‑building programs, and, perhaps most importantly, in the cultural expectation that government could step in to coordinate national crises. The lessons learned—prioritizing essential goods, aligning labor and industry, and giving voice to ordinary consumers—became the playbook for everything from the Marshall Plan’s reconstruction efforts to the 1950s’ suburban housing boom.

In the end, the legacy of the OPA’s seven commissioners is not a single monument but a web of interlocking achievements:

• Knudsen’s insistence on a unified production schedule laid the groundwork for modern defense procurement.
• Henderson’s labor‑management strategies foreshadowed the collective‑bargaining models that would dominate post‑war industry.
• Stettinius’s raw‑material allocation system became a template for the strategic stockpiles that still underpin national security.
• Elliott’s consumer‑advocacy framework proved that public trust could be a decisive factor in wartime policy, a principle that resurfaced in later price‑control battles.
• Davis’s agricultural coordination ensured that the home front never starved, reinforcing the notion that food security is as vital to victory as ammunition.

The war’s outcome was decided on battlefields abroad, but it was also forged in the conference rooms of a modest office on Pennsylvania Avenue, where seven men and women, each an outsider in his or her own right, managed to turn a nation’s civilian economy into a war machine that could outproduce any adversary. Their story is a reminder that in moments of existential crisis, the most powerful weapons are not always tanks or planes, but the willingness of disparate leaders to find common ground—and to let the public sit at the table when the stakes are highest.
