You probably think of the fax machine as a relic of the 1980s, sitting in a beige office next to a Rolodex and a jar of rubber bands. Maybe you associate it with the 90s dot-com boom or those screeching dial-up tones that sounded like a robot having a mid-life crisis. But honestly? The timeline is way messier than that. When the fax machine was invented, Abraham Lincoln was still a relatively unknown lawyer in Illinois and the American Civil War hadn't even started.
It’s wild.
Most people assume Alexander Graham Bell had to get the telephone working before we could send images, but history doesn't care about our assumptions. A Scottish inventor named Alexander Bain patented the first "Electric Printing Telegraph" in 1843. That is 33 years before the telephone patent. Think about that for a second. We had the technology to send a synchronized image across a wire before we could reliably send a human voice.
The Clockwork Genius of 1843
Bain wasn't trying to build an office tool for lawyers to send contracts. He was a clockmaker by trade, and you can see that influence in how the first fax machine was invented. He used two pens and two synchronized pendulums. One pendulum would scan a message written in raised metal letters, and the other would "write" it on the receiving end using chemically treated paper.
It was slow. It was clunky. It looked like something out of a steampunk novel.

But it worked.
The genius—and the headache—was the synchronization. If one pendulum swung even a fraction of a second faster than the other, the image came out as a garbled mess of black streaks. Bain’s breakthrough was basically the birth of scanning. He figured out that you could break an image down into "lines," which is exactly how your modern computer monitor or 4K TV works today. He just did it with brass gears and chemical reactions instead of pixels.
Why didn't it take off immediately?
The infrastructure just wasn't there. You can have a brilliant machine, but if there are no lines to run it on, it’s just a very expensive paperweight. Plus, the 1840s were dominated by the Morse telegraph. Morse was simpler. Dots and dashes were easier to send over long distances than the complex electrical pulses required for an image.
The Pantelegraph and the First Commercial Success
Fast forward to the 1860s. An Italian priest and physicist named Giovanni Caselli took Bain’s messy idea and actually made it commercially viable. He called it the Pantelegraph. This wasn't some lab experiment; it was a real service used by the French government.
Imagine being a Parisian in 1865. You could walk into a telegraph office and send a handwritten signature or a drawing to someone in Lyon. This was decades before people had lightbulbs in their homes. Caselli’s machine was massive—nearly seven feet tall. It used a massive lead weight and a complex system of magnets to keep the pendulums in perfect sync.

Caselli was arguably the first person to prove that the world wanted a "hard copy" of information. Symbols mattered. Signatures mattered. A telegram could tell you that you’d been fired, but a fax could show you the official seal that made it real.
The Great Stagnation
Despite the Pantelegraph’s success, the fax machine spent the next century as a niche tool. It was too big. It was too expensive.
During the early 20th century, the technology started splitting into specialized fields. The "Wirephoto" changed journalism forever. In 1924, AT&T scientists figured out how to send photographs over telephone lines using "telephotography." This is why, if you look at newspapers from the 1930s, you start seeing grainy photos of events that happened only hours before on the other side of the country.
Before this, photos had to be physically mailed or put on a train.
Radiofax followed soon after. Ships at sea began receiving weather maps via radio waves. It’s actually one of the few places where fax technology is still actively used today. If you’re on a cargo ship in the middle of the Atlantic, you’re likely still pulling down weather charts via a radio fax broadcast because it’s more reliable than a shaky satellite internet connection in a storm.
The Xerox Revolution and the Office Boom
If the fax machine was invented in 1843, why did we have to wait until the 1960s to see it in an office?
The answer is the "Magnafax Telecopier." Released by Xerox in 1966, this was the first machine that didn't require a specialized technician to operate. It weighed 46 pounds. It was basically a giant suitcase that you hooked up to a standard telephone line.
It took six minutes to send a single page.
Six minutes!
You could make a sandwich in the time it took for one memo to crawl across the phone line. But for businesses, this was a miracle. No more couriers. No more waiting two days for the post. It fundamentally changed the pace of business. If you needed a contract signed in London and you were in New York, you didn't have to wait a week. You waited six minutes (plus the time it took to dial the operator).
Why the Fax Refuses to Die
This is the part that drives IT professionals crazy. It’s 2026, we have instant encrypted messaging, fiber-optic speeds, and cloud-based document signing, yet the fax machine persists. Especially in Japan, Germany, and the United States healthcare system.
Why?
- The Legal Ghost: In many jurisdictions, a faxed signature is still legally "more" valid than a digital scan because it’s considered a direct point-to-point transmission. It’s harder to "spoof" a fax line than an email.
- Medical Privacy: In the US, HIPAA regulations are a nightmare. Faxing is often seen as a "safe harbor" because it doesn't leave a digital trail on a server in the same way an unencrypted email does. Doctors are notoriously slow to change their workflows. If it isn't broken, don't buy new software.
- The User Interface: Honestly, for some people, putting a piece of paper in a tray and hitting a number is just easier than scanning a PDF, attaching it to an email, and hoping it doesn't get caught in a spam filter.
How the Fax Machine Changed the World
We tend to look at the history of tech as a straight line, but the fax machine is a weird loop. It predates the tools we thought were its ancestors.

When the fax machine was invented, it set the stage for the "instant" world we live in now. It taught us to expect that an image could exist in two places at once. It paved the way for the scanner, the inkjet printer, and even the way the internet handles data packets.
Actionable Insights for the Modern Age
If you’re still dealing with faxing in your professional life, or if you’re just fascinated by the staying power of "obsolete" tech, here is how to handle it:
- Move to E-Fax: If you are still paying for a physical copper landline just for a fax machine, you are burning money. Use a digital bridge service. They give you a fax number but deliver the documents to your email as a PDF. It’s more secure and cheaper.
- Check Your Security: If you work in a field like law or medicine, remember that physical faxes sitting on a communal tray are a massive security risk. If you must fax, use a "secure receive" function where a PIN is required to print the document.
- Audit Your Workflow: Ask why you are faxing. Is it because of a law, or just because "that's how we’ve always done it"? Many institutions that claim they "only accept faxes" actually accept secure digital uploads, but they haven't updated their instruction manuals since 2004.
- Appreciate the History: Next time you see a fax number on a business card, think about Alexander Bain and his pendulums in 1843. We are still using a variation of a Victorian clockmaker’s dream to run 21st-century commerce.
The fax machine isn't just a piece of hardware. It's proof that a good idea, even if it's over 180 years old, can be incredibly hard to kill. It survived the telegraph, the landline, and the early internet. While its days in the average home are long gone, its DNA is buried deep in every screen you look at.
It’s the survivor of the tech world. It’s clunky, it’s loud, and it’s surprisingly brilliant.
