When Arthur R. Butz, an electrical engineering professor at Northwestern University, published The Hoax of the Twentieth Century in 1976, he didn't just write a book. He basically threw a hand grenade into the middle of the academic world. Most people look at the title and assume it’s a fringe conspiracy theory written by someone in a basement. But that's not quite what happened. Instead, Butz used his background in systems analysis to try and dismantle the historical record of the Holocaust, creating what many historians consider the "foundational text" of modern Holocaust denial.
It’s a heavy subject. Honestly, it’s uncomfortable.
But to understand why this book still circulates in certain corners of the internet and why it caused such a massive legal and academic firestorm, you have to look at how Butz approached the material. He didn't use the typical emotional rhetoric you might expect. He used a dry, technical, and almost clinical tone. This "scholarly" veneer is exactly why it was so effective at finding an audience among those skeptical of mainstream history.
Why The Hoax of the Twentieth Century changed the game
Before 1976, most denial literature was pretty crude. It was mostly pamphlets and angry rants. Butz changed that. He brought the pedigree of a tenured professor at a prestigious American university. That mattered. It gave the movement a sort of "intellectual" credibility it desperately craved.
He didn't argue that nothing happened during World War II. That would be too easy to disprove. Instead, Butz focused on the technical feasibility of the gas chambers. He looked at the logistics of the crematoria. He questioned the numbers. Basically, he took the tools of an engineer—logistics, chemistry, and data—and applied them to a historical event to try and prove it was a massive propaganda effort.
Historians like Deborah Lipstadt and Robert Jan van Pelt have spent decades debunking these specific claims. Van Pelt, in particular, is an architectural historian who provided massive amounts of evidence during the famous Irving v. Penguin Books trial to show that the structures at Auschwitz were indeed designed for mass killing. But for those who read Butz, the technical jargon he used acted as a shield against simple historical rebuttals.

The Northwestern University standoff
You can imagine the chaos at Northwestern. A tenured professor was essentially calling one of the most documented genocides in history a "hoax."
The university was stuck. On one hand, they had a faculty member spreading misinformation that many found abhorrent. On the other, they had the principles of academic freedom and tenure. The school's president at the time, Robert Strotz, famously defended Butz’s right to publish his "monstrous" views while simultaneously distancing the university from them.
This created a massive debate that still pops up today in discussions about free speech on campus. Does a professor have the right to be "wrong" about history if it’s outside their field of expertise? Butz was an engineer, not a historian. Yet, he was using his title to lend weight to his claims. It’s a messy situation. Students protested. Alumni threatened to pull funding. Butz, however, stayed on the faculty until his retirement in the early 2000s. He never recanted.
Breaking down the "Technical" arguments
Butz focused heavily on the International Red Cross reports and the lack of a "smoking gun" written order from Hitler. He argued that the missing paper trail was proof of a conspiracy.
However, historians point out that the Nazi regime was notorious for using "language rules" (Sprachregelung) to hide their tracks. They used euphemisms like "special treatment" or "resettlement." Butz dismissed this. He claimed that the gas chambers were actually just delousing chambers intended to fight typhus.

- He ignored the chemical traces of Zyklon B found in the ruins that were inconsistent with simple delousing.
- He dismissed the sheer volume of eyewitness testimony from both survivors and the perpetrators themselves.
- He treated the entire post-war legal system, including the Nuremberg Trials, as a choreographed sham.
It’s a classic example of confirmation bias. If you start with the premise that a hoax exists, you can find "evidence" in the gaps of any historical record. No record is 100% complete. Butz lived in those gaps.
The impact on international law
The book didn't just stay in the US. It traveled. In Germany and Canada, where "Holocaust denial" can lead to criminal charges, the book became a contraband item.
In the late 1970s and 80s, the book became a central piece of evidence in the trials of Ernst Zündel in Canada. Zündel was a publisher who distributed Butz’s work. The legal battles that followed were some of the most exhaustive examinations of the Holocaust ever conducted in a court of law. It forced the legal system to figure out how to handle "historical" claims that crossed the line into hate speech or public mischief.
The engineering of a narrative
What's wild is how Butz used his background. He wasn't looking at diaries or letters. He was looking at "throughputs." He calculated the amount of coke (fuel) required to burn a body. He looked at the dimensions of rooms.
If the math didn't work for him, he concluded the event didn't happen.

But as Jean-Claude Pressac (a former denier who eventually became a prominent researcher of the gas chambers) discovered, the "technical" impossibility Butz claimed was based on flawed data. Pressac actually went to the archives and found the original blueprints and invoices for the crematoria. He found that the "engineering" Butz questioned was actually terrifyingly efficient and well-documented by the Germans themselves.
Why people still talk about it
The internet changed everything for books like this. In the 70s, you had to find a specialty bookstore or order it via mail. Today, it’s a PDF click away. It serves as a gateway for people who are already skeptical of "mainstream" narratives.
Because it doesn't read like a typical hate-filled manifesto, it catches people off guard. It feels like a textbook. That’s the danger. It’s "denial in a suit and tie."
Actionable insights for navigating historical controversy
When dealing with claims from books like The Hoax of the Twentieth Century, it's vital to look past the academic tone and check the sources. Historical literacy isn't just about knowing dates; it's about understanding how evidence is verified.
- Verify the expertise: Always check if the author is writing within their trained field. An engineer might understand structural stress, but that doesn't make them an expert on 1940s German linguistics or bureaucratic records.
- Look for the "Consensus" counter-arguments: Serious history is peer-reviewed. Look at the works of Christopher Browning or Richard J. Evans. They have addressed the "technical" claims of deniers with actual primary source documents that Butz conveniently overlooked.
- Check the primary sources: Don't take a summary of a document (like a Red Cross report) at face value. Often, deniers take one sentence out of context while ignoring the other 500 pages of the report.
- Identify the "Gaps" logic: Be wary of any argument that says "Because we don't have a photo of X, then X never happened." History is built on a "convergence of evidence"—thousands of small pieces of data that all point to the same conclusion.
The legacy of Arthur Butz is a reminder that credentials don't always equal truth. Even a tenured professor can build a massive, complex argument on a foundation of sand. Understanding the mechanics of how he built that argument is the best way to see where it falls apart.
