Picture this. It’s 1991. The internet as you know it doesn’t really exist yet. The World Wide Web is, in the words of one of its future architects, “little more than a glint in CERN’s eye.” And somewhere in a corridor at the University of Cambridge Computer Laboratory, a stainless steel filter coffee machine is doing what coffee machines do — brewing, cooling, sitting forgotten — while fifteen researchers on the other side of the building stare at screens and wonder if the trip downstairs is worth the risk.
It wasn’t the machine itself that was important. It was the ritual. A fresh pot came on. It didn’t last. And every time one of the fifteen or so members of the Systems Research Group hauled himself up two or three flights of stairs, coffee mug in hand, only to find the carafe empty, another tiny piece of his afternoon died inside.
So they did what frustrated computer scientists have always done when confronted with a boring, repetitive problem: they automated it. What happened next — one afternoon’s crazy idea, really — would become the world’s first webcam, run for a decade, attract millions of viewers, make the front page of The Washington Post, and end up on eBay.
The “Trojan Room” and a Day’s Worth of Engineering
The room was nicknamed the Trojan Room — a name its creators later acknowledged caused “some amusement to American readers.” The coffee pot lived in the corridor just outside. One piece of salvage equipment — an idle video frame-grabber bolted to an Acorn Archimedes machine — was repurposed for a new, very important mission.
Quentin Stafford-Fraser, a research scientist who’d become Cambridge’s first college Computer Officer at Gonville and Caius College in 1989, clamped a Philips camera onto a laboratory retort stand, pointed it at the Krups coffee machine, and ran cables under the floor. His colleague Paul Jardetzky — a California-raised PhD student with a BA in Applied Mathematics from Berkeley — wrote a server program that grabbed a new image every few seconds.
Stafford-Fraser then wrote the client side: a small X Window System application called XCoffee. It popped up an icon-sized greyscale thumbnail in the corner of everyone’s workstation screen, updating roughly three times a minute. “But that was fine,” Stafford-Fraser later wrote, “because the pot filled rather slowly, and it was only greyscale, which was also fine, because so was the coffee.”
The whole thing took about a day to build. “Probably only 12 lines of code, probably less,” recalled Dr. Martyn Johnson, who would later bring the whole system online to the web. The image resolution was a cozy 128×128 pixels. One frame per second on the desktop, three refreshes per minute on the network. In Quentin’s memory, it was “rather more useful than anything else I wrote while working on networks” and “made a better topic of conversation at dinner parties than ATM protocols.”
The first published record came on January 27, 1992, when networking legend Bob Metcalfe wrote about it in his Communications Week column after visiting the lab. Emboldened, the team began joking about other monitoring systems — XSandwichVan, XPrinterOutputTray — but the frame-grabber eventually died, and the whole setup might have quietly expired.
Both went on to interesting careers elsewhere. They thought the coffee pot was behind them. They were wrong.
Mosaic, Two Million Visitors, and the Meme Before Memes
In early 1993, a student named Marc Andreessen at the University of Illinois released NCSA Mosaic, the first popular graphical web browser. For the first time ever, images could be displayed inline on web pages rather than opened in separate viewer windows. People suddenly realized: you could put pictures on the web. Not just text.
At Cambridge, researchers Daniel Gordon and Martyn Johnson saw the opportunity immediately. Johnson wrote a tiny HTTP script — again, something in the neighborhood of a dozen lines — that served the most recent captured frame of the coffee pot to any web browser. On November 22, 1993, the Trojan Room Coffee Pot went live on the World Wide Web.
And the internet, still young and desperately looking for things to do, fell in love.
The feed attracted roughly 2.4 million visitors. People from Japan to Brazil tuned in to watch a greyscale filter machine in a British university corridor. International viewers asked that the lights be left on overnight so they could see the pot in daylight. American tourists showed up at the Cambridge Computer Lab asking to be shown the machine in person. The pot was covered by the BBC, mentioned on the long-running radio drama The Archers, and spoofed in a 1998 April Fools’ RFC called the Hyper Text Coffee Pot Control Protocol — a specification for controlling coffee makers over HTTP that is still referenced in real web standards today as documentation for HTTP error code 418.
“Nothing else I’m ever involved in again in my life will get this much coverage,” Quentin Stafford-Fraser reflected later, “and it was just one afternoon’s crazy idea.”
Stafford-Fraser went on to co-create VNC — the remote desktop technology you’re probably using right now. He remains a Senior Research Associate at Cambridge. In November 2017 he received the Lovie Lifetime Achievement Award for “inventing the first-ever livestream with the XCoffee client program, thereby paving the way for the present-day proliferation of live video chat online and on handheld devices.”
The Last Frame
By 2001, the Computer Laboratory was relocating to its new home in the William Gates Building. The original Trojan Room, the aging Acorn Archimedes, the tangle of cable under the floor — all were being retired. The webcam had survived its frame-grabber, its original creators, and at least four or five different actual coffee machines mounted on the same stand. But now, at last, it was time.
The announcement was made in early 2001. Within weeks, the planned shutdown made the front page of both The Times of London and The Washington Post. The Guardian and Wired ran elegies. International television crews returned. A generation of web users who had never been to Cambridge discovered that they were, for some reason, grieving a coffee machine.
The camera ran until its final moment at 09:54 UTC on Wednesday, 22 August 2001. The last image ever captured was not of an empty pot. It was a photograph of three fingers about to press the power switch off — Gordon, Johnson, and Stafford-Fraser, signing out of a decade-long livestream.
Then there was the matter of the physical machine. The longest-serving camera subject — a Krups filter machine — was put up for auction on eBay. The sale attracted bidding from around the world. The winning bid was £3,350 (roughly $5,000 at the time), placed by the German news magazine Der Spiegel, whose editors felt something like a sacred obligation to preserve what had become, in their words, a piece of internet heritage. The proceeds were donated to the University of Cambridge Computer Laboratory Appeal Fund.
Krups employees refurbished the machine free of charge. It was shipped to Der Spiegel’s Hamburg office and switched back on — no longer connected to a webcam, but still making coffee for the newsroom. Then, in the summer of 2016, it found its final home. Der Spiegel placed it on permanent loan to the Heinz Nixdorf MuseumsForum in Paderborn, Germany — one of the world’s largest museums devoted to the history of computing and information technology. It sits there today, under glass, not brewing anything, watched by visitors who may or may not know that this ordinary Krups machine is the exact reason you can watch a livestream of a penguin colony or a construction site or a puppy pile today.
Every webcam, every baby monitor, every Ring doorbell, every security feed watching a parking lot — every single pixel of surveillance and delight that now floods the internet — descends from this moment in 1991 when some computer scientists at Cambridge got tired of climbing stairs for nothing.
Necessity might be the mother of invention. But laziness — the specific, dignified laziness of an academic unwilling to make a fruitless trip — is definitely its father.
Go make yourself a cup. A fresh one, if you please — and maybe check it’s still there before you go.

Fresh-roasted coffee tastes like nothing else on your grocery shelf. Most weekdays, Francesco’s ships beans within 12 to 16 hours of roasting — so when your bag lands on your counter, it’s barely cooled from the roaster. Try one bag. You’ll know the difference on the first sip.
