The World’s First Radio Broadcast: A Christmas Eve Miracle

Imagine you’re aboard a cargo ship in the middle of the Atlantic Ocean on a frigid December night in 1906. It is Christmas Eve, but instead of enjoying festive holiday moments with your family, you’re stuck on the ship. The sea’s rolling under you like a moody drunk, the stars are crisp above, and the only thing more monotonous than the voyage is the steady beep-beep-beep of Morse code tapping away from your radio receiver. Abruptly, a message comes through that catches your full attention:

-… . / .–. .-. . .–. .- .-. . -.. / ..-. — .-. / … — — . – …. .. -. –. / — ..-. / –. .-. . .- – / .. -. – . .-. . … – / – — / ..-. — .-.. .-.. — .–

Or, translated into the King’s English:

“Be prepared for something of great interest to follow.”

“Something of great interest?” you think. That’s the kind of message that could mean anything. A warning? A prank? Maybe a distress signal from some doomed vessel being eaten by the Atlantic. But no — what followed was not danger. It was something much stranger and, in its own way, miraculous.

A Strange Morse Code Message

Before we get to the big moment, we should talk about how we even got to the point where a simple message like “Be prepared for something of great interest” could reach a ship in the middle of the ocean. The idea of sending signals through the air had been around for decades, but for most of that time it was about as glamorous as watching paint dry. If you want to know how exciting that is, scientists have conducted a study on the subject, because of course they have.

Wireless communication before 1906 was mostly the domain of the telegraph — a technology that dates back to the 1830s. The electric telegraph was revolutionary in its own right, replacing days- or weeks-long message delivery by horse or ship with nearly instantaneous communication. But it had two glaring problems: it required a physical wire between sender and receiver, and it spoke a language only telegraph operators understood: a cryptic mix of dots and dashes invented by Samuel Morse.

By the late 19th century, scientists were getting itchy fingers about cutting the wire. Men like James Clerk Maxwell and Heinrich Hertz had already proven that electromagnetic waves existed and could be sent through the air. Italian inventor Guglielmo Marconi became the poster boy of early wireless telegraphy by sending Morse code messages over longer and longer distances — most famously across the Atlantic in 1901. But even Marconi’s work was still essentially a glorified beeping machine. Human speech and music remained stubbornly tied to wires.

Enter Reginald Aubrey Fessenden — a man who looked at all this progress and said, in effect, “Nice work, lads, but you’re still stuck in the nursery.”

Reginald Fessenden’s Revolutionary Experiment

Fessenden was born in 1866 in East Bolton, Quebec — and like many great inventors, he had the kind of mind that saw “impossible” as a personal insult. A former assistant to Thomas Edison (who famously described him as “the greatest wireless inventor in the world” — which, coming from Edison, was practically a knighthood), Fessenden was convinced that sending sound through the air was not only possible but inevitable.

While Marconi and others were still clicking out Morse messages using spark-gap transmitters — devices that produced bursts of electromagnetic energy but couldn’t carry audio — Fessenden was experimenting with something radically different: continuous waves. Instead of sending a series of sparks, he aimed to generate a steady electromagnetic wave that could carry the complex vibrations of the human voice or musical instruments.

To do this, he developed the high-frequency alternator, a device capable of generating a continuous wave powerful enough for radio transmission. It was an audacious idea. It was also expensive, finicky, and prone to catastrophic breakdowns — which, as any inventor will tell you, is part of the fun. Fessenden’s early attempts were plagued by technical problems, including the rather dramatic failure of an alternator that exploded and showered molten metal across his lab. Lesser men might have taken that as a sign to pursue something safer, like beekeeping. Fessenden took it as proof he was on the right track.

By 1906, after years of trial, error, and more than a few singed eyebrows, Fessenden was ready for his grand demonstration. He set up a powerful transmitter at Brant Rock, Massachusetts, and invited ships at sea and wireless stations along the coast to tune in on Christmas Eve at 9 p.m. Eastern Time. Most of them probably expected another tedious series of dots and dashes. What they got instead was the dawn of a new age.

The First Words and Music Ever Heard Over Radio

At the appointed time, December 24, 1906, the dots and dashes conveyed the curious message: “Be prepared for something of great interest to follow.”

Moments later, instead of the familiar dots and dashes of the wireless telegraph, the receiver crackled to life with something no one had ever heard come through the air before: a human voice. Then music. Then scripture. The world’s first radio broadcast was taking place. And like most great leaps forward in history, it was brought to you by a brilliant, stubborn, occasionally insufferable human being who refused to accept that “good enough” was good enough.

The voice they heard was Fessenden’s. According to his own later accounts, he started with a brief spoken introduction — though, tragically, no one wrote down his exact words.

Fessenden later recalled that he began his short program with a phonograph record of “Ombra mai fu” (often called Largo) by George Frideric Handel. The stately opening bars, drifting invisibly across the cold December air, marked the first time in history that music had traveled through space without a single wire.

But he wasn’t done. Picking up his violin, Fessenden performed Adolphe Adam’s beloved carol “O Holy Night”, filling the receivers of astonished sailors with a tune more familiar from candlelit churches than shipboard radio rooms. Then, in a display of both scientific and musical ambition, he sang “Adore and Be Still” by Charles Gounod — a choice that proved the new medium could carry not only instruments but the human voice itself.

To close this unprecedented broadcast, Fessenden turned to the Gospel of Luke, reading aloud: “Glory to God in the highest, and on earth peace to men of good will.” (Luke 2:14) It was a fitting benediction for a night that would change the course of communication forever. In a world used to hearing only dots and dashes, humanity had just learned that the air itself could sing.

Every radio station, every podcast, every live concert streamed into your earbuds — all of it traces its lineage back to one Canadian scientist scraping out a Christmas carol into a crude microphone while sailors huddled around their receivers in disbelief.

Fessenden repeated the broadcast on New Year’s Eve, though there’s little evidence that anyone heard it that night. (Given the holiday, it’s entirely possible that most wireless operators were off celebrating the dawn of 1907 in the traditional fashion: by drinking something that could remove paint and swearing they’d never touch it again.)

How We Got There: The Long Road to the Airwaves

It’s tempting to treat Christmas Eve 1906 as the singular “birth of radio,” but the truth is messier — as truth tends to be. Fessenden’s broadcast was the first voice and music transmission, but it stood on the shoulders of decades of work by scientists, tinkerers, and eccentrics who pushed communication forward step by reluctant step.

The story arguably begins with Scottish physicist James Clerk Maxwell, who predicted electromagnetic waves in the 1860s — though Maxwell himself was more interested in equations than entertainment. Heinrich Hertz proved their existence in the 1880s, demonstrating that invisible waves could travel through space. He promptly declared the discovery had no practical use whatsoever and went back to his lab. (History would beg to differ.)

Marconi’s 1895 wireless telegraph was the first commercially viable use of those waves. By the turn of the century, he had connected ships to shore and even sent a transatlantic signal — a single Morse “S” — from Cornwall to Newfoundland. It was groundbreaking stuff, but as Fessenden noted with characteristic bluntness, “It is like trying to converse with one’s friend by firing a cannon.”

Fessenden wasn’t alone in seeking to improve on Marconi. Around the same time, others were tinkering with audio transmission. Lee de Forest, another pioneer and frequent thorn in Fessenden’s side, invented the Audion tube in 1906, which amplified weak radio signals and made commercial broadcasting possible. De Forest would later call himself the “Father of Radio,” which drove Fessenden absolutely mad. The two men loathed each other so much that their feud spilled into lawsuits, press releases, and even congressional hearings. If the history of radio has a soap opera subplot, it’s this bitter rivalry.

Still, it was Fessenden’s continuous wave experiments that made that first broadcast possible. And while the Brant Rock transmission didn’t immediately lead to Top 40 countdowns or morning traffic reports, it did prove beyond doubt that radio could be more than a glorified telegraph. It could carry voices, stories, music — all the messy, human sounds of life itself.

The Legacy of That Historic Night

If you’re picturing headlines and ticker-tape parades following Fessenden’s triumph, prepare to be disappointed. The first radio broadcast in history was, frankly, a bit of a non-event. Only a handful of people heard it. Most of the world had no idea it happened. Newspapers didn’t report it. Marconi didn’t send flowers. Life went on much as before, with the general public still blissfully unaware that human voices had just leapt across the Atlantic without wires.

But revolutions don’t always start with fireworks. Sometimes they start with a lonely scientist sawing away on a violin in the dark.

Fessenden continued his work, patenting more than 500 inventions over his lifetime, including sonar and radio direction-finding technology. He was never as rich or famous as Marconi, but in many ways, his work was more foundational. Modern radio, television, radar, and even Wi-Fi all owe something to the principles he demonstrated on that cold December night.

And while Fessenden’s name has faded from popular memory — a cruel fate for someone who helped create the soundtrack of the 20th century — the echoes of his work are everywhere. Every time a DJ talks over a song, every time a voice comes through a speaker to tell you the weather, the traffic, or the score of the match, you’re hearing the distant ripple of that first broadcast.

A Legacy Written in Waves

So, what began as a cryptic Morse message promising “something of great interest” turned out to be far more than that. It was the first ripple of a revolution. A few notes of “O Holy Night”, a reading from Luke, and a grainy phonograph record might not seem like much, but they were the sound of humanity’s voice leaping into the air — untethered, unstoppable, and destined to reshape the world.

From that Christmas Eve in 1906 to the podcasts we stream while pretending to work today, it’s all part of the same story: the history of radio communication and the wireless telegraphy breakthrough that became something far greater. And it all began with a man named Reginald Fessenden, who refused to stop at dots and dashes when he knew the human voice could do so much more.

So the next time you turn on the radio — or your Bluetooth speaker, or your Wi-Fi, or anything else that hurls invisible waves through the air — spare a thought for the man who, on one cold night in 1906, picked up a violin and taught the world how to listen.

Something of great interest, indeed.
