You probably think the fax machine is a relic of the 1980s, right next to shoulder pads and neon leg warmers. It feels like a piece of tech that arrived with the first chunky computers. But honestly, the inventor of the fax machine, a Scottish clockmaker named Alexander Bain, actually patented the thing in 1843.
1843.
Think about that for a second. That is more than thirty years before Alexander Graham Bell ever uttered a word into a telephone. It was well before the lightbulb was a practical reality. While people were still getting around in horse-drawn carriages and reading by candlelight, Bain was figuring out how to send an image across a wire. It’s kinda mind-blowing when you realize the "modern" office machine is actually older than the American Civil War.
The Clockmaker’s Brain Wave
Alexander Bain wasn't a corporate scientist. He didn't have a lab at Google or a grant from a major university. He was a guy who fixed clocks. But being a clockmaker back then meant you understood the mechanics of time and synchronization better than almost anyone else on the planet.
Bain’s big "aha!" moment happened when he realized he could combine his knowledge of electric clocks with the emerging telegraph technology. Telegraphs were great, sure, but they only sent pulses—dots and dashes. You needed a trained operator to decode the Morse. Bain wanted more. He wanted the actual image, the handwriting, the physical document to move through space.
He used a pendulum.
Actually, he used two pendulums. One was at the transmitter, and one was at the receiver. He figured out that if he could keep these two pendulums swinging in perfect synchronization, he could scan a surface and replicate it elsewhere. He used a clock to regulate the movement. It’s basically the same logic your modern printer uses when the print head moves back and forth, just using 19th-century gears and gravity.

How the First Fax Actually Worked
It wasn’t elegant. If you saw the first machine the inventor of the fax machine built, you wouldn’t recognize it as office equipment. It looked more like a science fair project gone rogue.
The original process involved a metal plate. You’d take your message and "write" it onto this plate using a special insulating ink. Then, a stylus attached to a swinging pendulum would sweep across the plate. Every time the stylus hit the metal, it completed a circuit. Every time it hit the ink, the circuit broke.
- The signal traveled through the telegraph wires.
- On the receiving end, another pendulum moved in sync.
- It swung across a piece of paper soaked in a chemical solution (potassium iodide).
- The electric pulse caused a chemical reaction, leaving a dark mark on the paper.
The result? A grainy, slightly smeared, but totally legible copy of the original. It was the world's first "facsimile."
The Battle with Morse
Bain didn't have it easy. Being a brilliant inventor is one thing; being a businessman in the 1840s was a whole different beast. He ran head-first into Samuel Morse.
Morse was protective of his patents. Very protective. When Bain tried to bring his chemical telegraph and facsimile technology to the United States, Morse sued him. It was a messy, protracted legal battle. Morse basically claimed he owned the rights to any communication using electricity over wires.
Bain eventually won a partial victory in court, but the legal fees and the stress took their toll. It’s one of those classic stories where the visionary gets sidelined by the guy with the better lawyers and the bigger brand name. Even though Bain was the true inventor of the fax machine, he never became a household name like Edison or Bell. He died in 1877, relatively poor and largely forgotten by the public, while the world was just starting to get excited about the telephone.

Why It Took a Century to Catch On
If the tech existed in 1843, why weren't people faxing each other in the 1890s?
Synchronization is hard.
Seriously, keeping two pendulums hundreds of miles apart swinging at the exact same speed is a nightmare. If one clock was even a fraction of a second off, the image would come out skewed or completely unreadable. It wasn't until the development of better motors and, eventually, radio and digital sync, that the fax became reliable enough for a secretary to use without a physics degree.
Then you have the infrastructure problem. You needed a dedicated wire. It wasn't like today where you just plug into a wall jack. It took the massive expansion of the global telephone network in the mid-20th century to give the fax a "highway" to drive on.
We also have to talk about the "Pantelegraph." About twenty years after Bain, an Italian priest named Giovanni Caselli took Bain’s designs and actually made them commercially viable. He set up a service between Paris and Lyon in the 1860s. People were actually sending faxes in the 1860s! But it was expensive and niche. It was the "private jet" of communication—cool, but not for everyone.
The Surprising Longevity of Bain's Idea
It’s weirdly poetic that the fax machine became the backbone of the 80s and 90s business world. Doctors, lawyers, and bankers obsessed over it. Why? Because a signature on a fax was legally binding in a way that an early email or a phone call wasn't.

Even today, in 2026, faxes haven't totally died. Japan still uses them extensively. The healthcare industry in the US is still weirdly dependent on them because of legacy security standards and HIPAA concerns.
We’ve moved to "e-fax" and digital scanning, but the fundamental logic—scanning a document line-by-line and converting it into a series of signals to be reconstructed elsewhere—is exactly what the inventor of the fax machine envisioned in his workshop in 1843.
Bain’s legacy isn’t just a dusty machine in a museum. It’s the very concept of image transmission. Every time you scan a QR code or send a PDF of a signed contract, you’re using the "Bain Method."
Putting History Into Practice
If you're interested in the history of tech or just want to appreciate how far we've come, there are a few things you can do to see Bain’s influence in the real world:
- Check out the Smithsonian or the Science Museum in London. They often have original telegraph and early facsimile components on display. Seeing the sheer size of the gears makes you realize how crazy the idea of "instant" transmission was back then.
- Compare the Patent 9745. If you’re a real nerd, look up Bain’s original 1843 British patent. The drawings are beautiful and show just how much he relied on clockwork logic.
- Audit your own tech. Look at how your office handles "analog-to-digital" conversion. Even high-end scanners today utilize the same "raster" scanning pattern—moving row by row—that Bain pioneered with his swinging pendulum.
- Acknowledge the underdog. Next time you're frustrated by a printer error, remember Alexander Bain. He fought Samuel Morse and the limits of 19th-century physics to give us the ability to send a picture through a wire.
Bain was a man out of time. He didn't just invent a machine; he invented a way for us to share our physical reality across distances. He deserves more than a footnote in a history book.
Actionable Insights for the Tech Enthusiast
- Study the "Sync" Principle: Research how modern "handshaking" protocols between devices (like Bluetooth or Wi-Fi) solve the same synchronization problems Bain faced with his pendulums.
- Legacy Systems Management: If you work in an industry like law or medicine that still uses fax, look into secure "Cloud Fax" APIs. These bridge the gap between Bain’s 19th-century concept and 21st-century encryption.
- Innovation Strategy: Use Bain’s story as a case study in "premature innovation." Sometimes being first is less important than having the right infrastructure (like the telephone network) to support your idea.
The fax machine isn't just a clunky box in the corner of the office. It's a 180-year-old dream that finally came true, then became mundane, then became "obsolete," and yet, somehow, it’s still here.
