Buried in the preface of a 1908 French manual on wireless telegraphy is a remarkably modern complaint — one that could have been written about today's academic journals or tech jargon. The author of the preface is no minor figure: Édouard Branly, the physicist whose coherer (a glass tube of metal filings that conducted electricity when struck by radio waves) was the detector that made early radio reception possible. Marconi's first transmissions across the Channel relied on Branly's invention.

The book itself, by engineer E. Monier, was titled — translated — "Wireless Telegraphy and Telemechanics Within Reach of Everyone." It was a popularization. And in his preface, Branly took a swing at his fellow scientists for deliberately keeping the subject murky:

"Bien que l'explication des effets obtenus ne présente pas de grosses difficultés, les auteurs qui se sont proposé de vulgariser les nouveaux procédés ont cru devoir les laisser dans une demi-obscurité, qui en impose à la bonhomie du lecteur et augmente probablement son respect pour la science."

In English: "Although the explanation of the effects obtained presents no great difficulties, the authors who have set out to popularize the new processes have thought it necessary to leave them in a semi-obscurity, which imposes on the reader's good nature and probably increases his respect for science."

This is, in 1908, a perfectly aimed accusation that we still recognize today: that experts sometimes inflate the difficulty of their subject to inflate their own status. Branly is essentially describing what modern critics call "epistemic gatekeeping" or what George Orwell would later attack in Politics and the English Language — the use of needless complexity to manufacture authority.

What makes the claim especially sharp:

• Branly was at the absolute pinnacle of the field he's accusing of obscurantism. He had every incentive to keep the magic mysterious, and he refused.
• He explicitly says the physics isn't actually hard — the difficulty is manufactured. Wireless telegraphy, he writes, is essentially "telegraphy by sparks," exploiting the property that capacitor-discharge sparks induce alternating currents in distant conductors. That's it.
• He praises Monier for not "yielding to the temptation to display a heavy bagage of abstract scientific knowledge" ("la tentation d'étaler un lourd bagage scientifique abstrait").

The forgotten lesson here isn't a recipe or a remedy — it's a piece of intellectual hygiene. A Nobel-adjacent physicist publicly stating that a great deal of the apparent mystery in cutting-edge science is theatrical. Modern readers will recognize the pattern instantly: the consultant's PowerPoint deck full of unnecessary acronyms, the medical literature that refuses to say "high blood pressure," the AI papers that hide simple ideas behind dense notation. Branly saw the same pattern in 1908 radio, and he was annoyed enough to say so in print.
