“That’s my Thunder; by G—! How these Rascals use me! They will not let my Play run, but steal my Thunder.”
— John Dennis, as recorded in a 1747 biographical compilation of
English dramatists
I first encountered this phrase during one of the worst professional weeks of my life. A colleague had pitched a project strategy I’d quietly developed over months — word for word, in a meeting I hadn’t been invited to. A friend texted me that evening with no explanation, just a single line: ”They will not let my play run, but steal my thunder.” I didn’t recognize it. I assumed she’d made it up. But the phrase landed with the precision of something that had been waiting specifically for that moment, and I sat with it for a long time in the dark, feeling simultaneously furious and strangely comforted. Later, I looked it up — and what I found was far richer, stranger, and more human than I ever expected. The story behind this phrase stretches back over three centuries, rooted in a theatrical catastrophe, a furious inventor, and one of the most colorful grudges in literary history.
The Man Behind the Thunder: Who Was John Dennis?
To understand the phrase, you first need to understand the man who allegedly shouted it. John Dennis was an English playwright, poet, and literary critic who lived from 1657 to 1734. He was, by most contemporary accounts, a man of fierce opinions and volcanic temperament. He wrote plays, essays, and criticism with equal intensity — and he made enemies with remarkable efficiency.
Dennis clashed publicly with Alexander Pope, Jonathan Swift, and a parade of other literary figures. Pope, in particular, seemed to take genuine delight in mocking Dennis across multiple works. Their rivalry was personal, bitter, and enormously productive for English literary history — even if it was miserable for both participants.
Despite his combative reputation, Dennis made real contributions to theatrical craft. He thought seriously about stagecraft, dramatic theory, and the mechanics of theatrical illusion. That seriousness led directly to the invention at the center of this story.
The Invention: A New Kind of Thunder
In 1709, Dennis staged his tragedy Appius and Virginia at the Theatre Royal in Drury Lane. The play failed. Audiences rejected it. Critics were not kind. By any measure, the production was a disaster.
However, Dennis had developed something genuinely innovative for the production: a new method for simulating the sound of thunder on stage. The exact mechanics of this technique have been debated across centuries. One account, preserved in a 1791 book about the painter William Hogarth, described the sound as coming from mustard bowls rattling overhead — a vivid, slightly absurd detail that rings with theatrical authenticity.
The play closed. The thunder stayed.
The theatre company, apparently impressed with the sound effect even while dismissing the drama that introduced it, continued using Dennis’s thunder technique in subsequent productions. This was, to put it mildly, not something Dennis accepted gracefully.
The Moment That Launched a Thousand Phrases
A few nights after his own play’s failure, Dennis attended a performance of Macbeth at the same theatre. He sat in the pit — the ground-level seating area directly in front of the stage. Then the thunder rolled. And Dennis recognized it immediately.
What happened next depends on which account you read. Multiple versions of the story circulated across the eighteenth century, each slightly different in wording and dramatic detail. However, they all agree on the essential shape of events: Dennis leapt up, enraged, and shouted something memorable about his thunder being stolen.
The earliest known written record of this incident appeared in Alexander Pope’s The Dunciad: With Notes Variorum, and the Prolegomena of Scriblerus, published in its second edition in 1729. Pope’s version, presented in a footnote rather than in the poem itself, recorded Dennis as shouting:
“S’death! that is my Thunder.”
Notably, Pope’s version does not include the word “steal.” Dennis simply claims ownership — furious, direct, and unambiguous. The verb “steal” came later.
How the Wording Evolved Over Time
In 1734, a sardonic biography titled The Life of Mr. John Dennis: The Renowned Critick repeated the story with nearly identical wording to Pope’s account. The author described the theatre company’s use of Dennis’s invention in other productions as “a Piece of Theft” — but still quoted Dennis as crying out ’Sdeath! that’s my THUNDER! rather than explicitly accusing anyone of stealing.
The pivotal shift arrived in 1747. A compilation of biographical sketches of English dramatists included an account of Dennis that introduced the fully formed phrase for the first time in print. This version gave Dennis a much longer, more theatrical outburst:
“That’s my Thunder; by G—! How these Rascals use me! They will not let my Play run, but steal my Thunder.”
This is the version that history remembered. It carries everything: the indignation, the specific grievance, the sense of double injury. His play failed and they took his best idea. The phrase captured something universal about creative theft — and it stuck.
By 1761, A New and General Biographical Dictionary offered yet another variation, with Dennis crying out: ”They will not have my play, yet steal my thunder.” The core complaint remained consistent across all versions, even as the specific words shifted with each retelling.
The Most Theatrical Version of All
Among the various accounts, the most dramatically satisfying version appeared in an 1791 book about William Hogarth. In this telling, Dennis didn’t just shout — he grabbed his walking stick and bellowed with such force that he drowned out the actors on stage:
“Eternal curses light on these scoundrels! they have stolen my thunder, and don’t know how to roll it!”
This version adds a delicious extra layer of insult. Dennis wasn’t just angry that they stole his technique. He was furious that they were doing it badly. The creative proprietor, outraged not only by theft but by incompetence — it’s almost impossible not to sympathize, even across three centuries.
From Literal to Figurative: The Phrase Enters Common Use
For decades, the phrase circulated primarily as an anecdote about Dennis specifically. However, language has a way of escaping its origins. By the early nineteenth century, “stealing someone’s thunder” had begun its transformation into a general-purpose idiom.
The earliest known figurative use appeared in The Eclectic Review in February 1831. A book reviewer, discussing the work of theologian Richard Whately, wrote: ”We will not charge Dr. Whately with ‘stealing our thunder.’” The phrase appeared in quotation marks — a signal that the writer recognized it as a borrowed expression, already familiar enough to invoke without explanation.
By 1843, a New York newspaper used the phrase in a political context, telling a rival paper: ”Don’t steal our thunder, if you please.” The quotation marks had disappeared. The phrase had arrived.
Additionally, an 1854 dialogue collection extended the metaphor playfully, with a character complaining that someone had stolen his story “after telling me there was no lightning in it.” This kind of playful extension only happens to phrases that have genuinely embedded themselves in common speech.
What the Phrase Actually Means — and Why It Endures
Today, “stealing someone’s thunder” describes at least two related but distinct behaviors. First, it means taking credit for another person’s idea or work. Second, and perhaps more commonly, it means upstaging someone — grabbing attention at a moment that rightfully belonged to them.
Both meanings trace back to the Dennis story in recognizable ways. His play failed, and the theatre company took his invention without acknowledgment — that’s the credit-theft reading. But there’s also something about upstaging in the story: the thunder that should have accompanied his drama now accompanied someone else’s triumph. His creative child had been adopted into a more successful family.
The phrase endures because the feeling it describes is genuinely universal. Creative people recognize it immediately. Anyone who has watched a colleague present their idea in a meeting — or seen a sibling announce their engagement at someone else’s wedding — knows exactly what Dennis felt in that pit at Drury Lane.
The Pope Connection: Credit, Mockery, and Legacy
It’s worth pausing on the fact that Alexander Pope preserved this story in the first place. Source Pope and Dennis despised each other. Pope had mocked Dennis savagely in The Dunciad and elsewhere. So why did Pope bother recording the thunder anecdote at all?
The answer likely involves a mixture of motives. The story made Dennis look ridiculous — a failed playwright throwing a tantrum in a theatre. From Pope’s perspective, that was useful. However, the story also, perhaps unintentionally, preserved something genuine about Dennis’s ingenuity. You cannot tell the thunder story without acknowledging that Dennis invented something worth stealing. Pope’s mockery accidentally became a monument.
This irony runs deep. The man who most wanted to diminish Dennis’s legacy ended up being the primary reason we remember him at all. Without Pope’s footnote in The Dunciad, the anecdote might have vanished entirely. Instead, it survived — and with it, one of the most durable phrases in the English language.
Misattributions and Muddled Histories
Because the phrase passed through so many hands and so many retellings, its origins became genuinely confused over time. Source Some sources attributed the invention of theatrical thunder to Pope himself, or described the anecdote without naming Dennis at all. The 1791 Hogarth account, for instance, credited Pope with the claim that Dennis invented stage thunder — which adds a layer of indirect attribution that further complicates the record.
Moreover, the exact words Dennis used will never be confirmed. No contemporary transcript exists. Every version of his outburst comes from accounts written years or decades after the fact, filtered through writers with their own agendas. Therefore, the phrase “they will not let my play run, but steal my thunder” represents the most dramatically satisfying reconstruction of what Dennis said — not necessarily a verbatim record.
Nevertheless, the essential facts hold up across multiple independent sources: Dennis invented a thunder effect, the theatre reused it without permission, and Dennis reacted with spectacular public fury. The specifics of his exact words matter less than the truth of the situation they described.
Why This Story Feels So Modern
Strip away the eighteenth-century setting, and the Dennis story reads like something that could happen today. A creator develops something innovative for a project that fails commercially. The institution keeps the innovation and discards the creator. The creator watches their work benefit someone else — without credit, without compensation, without acknowledgment.
In the age of intellectual property disputes, content theft, and viral idea-borrowing, the phrase has never felt more relevant. Source Dennis’s furious outburst in that theatre pit resonates precisely because the injustice he felt is one that creative people continue to experience in every field and every era.
His play failed. His thunder lived on. And somehow, three centuries later, so does his anger — transformed into a phrase that anyone who has ever had an idea borrowed without credit can reach for immediately.
Conclusion: A Failed Play’s Immortal Legacy
John Dennis never achieved the literary reputation he sought. His plays are largely forgotten. His critical feuds are remembered mainly as footnotes to more famous careers. However, in one furious moment in the pit of Drury Lane Theatre, he said something so perfectly human that it outlasted everything else he ever wrote.
The phrase “steal my thunder” traveled from a specific theatrical grievance in 1709 to a general English idiom by the 1830s, crossing the Atlantic by the 1840s and embedding itself so deeply in common speech that most people who use it today have no idea where it came from. That journey — from one angry man’s outburst to a universal expression of creative injustice — is, in its own way, a kind of immortality.
Dennis would probably find that ironic. His greatest contribution to the English language wasn’t a play, a poem, or a piece of criticism. It was a complaint. But then again, the best phrases often are.
