The Story
In the 1890s, self-taught inventor Simon Lake was racing to prove that a boat could travel and work along the ocean floor, not just dive beneath the surface. His first effort, the Argonaut Jr., was a modest hand-cranked craft he built and tested in the waters off Atlantic Highlands, launching it in the harbor in 1895. Crude as it was, it validated Lake's ideas about wheeled, bottom-crawling submersibles and set him on the path to the larger Argonaut and a long career as a rival to fellow submarine pioneer John Holland. The vessel standing here today is a full-size replica, rebuilt in 1994 by the Atlantic Highlands Lions Club to honor that local chapter of American invention.
Why it matters
This unassuming harbor was a proving ground for American undersea technology at the dawn of practical submarine design, a field that would reshape both exploration and naval warfare in the twentieth century.
The story behind this marker
AI contextThe era
In the last decades of the nineteenth century, America was in love with the machine. Factories were multiplying, electric lights were replacing gas lamps, and the country brimmed with tinkerers convinced that the next great invention was theirs to build. The waters off New Jersey, where the Atlantic met the busy shipping lanes into New York, were a natural place for that ambition to turn toward the sea.
One of the great unsolved puzzles of the age was the submarine. Inventors on both sides of the Atlantic had dreamed for generations of a boat that could travel beneath the waves, but the practical problems — air, buoyancy, steering blind in the dark — had defeated nearly all of them. By the 1890s, though, the pieces were finally coming together, and a handful of determined Americans were racing to be first.
The quiet harbor at Atlantic Highlands was an unlikely laboratory for that race. But it was here, in the mid-1890s, that a self-taught inventor set out to prove an idea that most of his rivals had overlooked entirely.
People & events
That inventor was Simon Lake, and the idea that set him apart was deceptively simple. While others focused on diving straight down, Lake was fascinated by the notion of a submarine that could travel along the sea floor — a boat with wheels that could roll across the bottom, letting a crew work, salvage, and explore in the shallows rather than merely pass through the water above.
To test the concept, Lake built the Argonaut Jr. in 1894, a modest experimental craft, and launched it in the harbor here in 1895. It was a plain, hand-powered vessel, crude by the standards of the warships that would follow. But it worked well enough to prove his principle, and it launched a career that would make Lake one of the recognized pioneers of the American submarine, developing larger and more capable vessels in the years that followed.
The boat that stands at this spot today is not the original. It is a full-size replica, reconstructed in 1994 by the Atlantic Highlands Lions Club, with Lion Carl Swanson heading the project — a community's way of marking the fact that a genuine piece of invention history began in their own harbor.
Its place in the American story
The story of the submarine is usually told as a naval one — of stealth, of torpedoes, of the world wars still to come. But its roots lie in exactly this kind of hopeful, hands-on experiment, carried out by inventors working with their own money and their own hands, long before any navy took the idea seriously.
Simon Lake's particular contribution — the vision of a submersible that could work along the ocean floor — pointed toward a future that went well beyond warfare. The same principles would eventually shape undersea salvage, exploration, and research, fields that let humans study a part of the planet that had always been out of reach.
That so much of this began in a small New Jersey harbor is a reminder of how American innovation often worked in that era: not in grand government laboratories, but in the workshops and waterfronts of ordinary towns, where a stubborn tinkerer with an idea could still change the course of a technology.
If you visit
Come to see something you will not find in many places: a full-size submarine sitting on dry land, right where the American undersea story got one of its first real tests. The replica is meant to be looked at up close, so take your time studying its shape — notice how little it resembles the sleek machines the word "submarine" usually brings to mind.
Stand for a moment and look out over the harbor. The water here is the same stretch where the original was floated in the 1890s, and it takes only a little imagination to picture a hand-cranked experimental boat easing out among the working vessels of the day.
It makes a rewarding stop on a drive along the Monmouth County shore, an easy pairing with the beaches and overlooks of the Atlantic Highlands. Give a thought, too, to the local Lions Club members who rebuilt it — the marker is as much a monument to a community's pride in its own history as it is to the inventor himself.

Fort Monmouth Avenue of Memories
Oceanport, NJ
Fort Monmouth in Oceanport was for generations the home of the U.S. Army Signal Corps, the branch responsible for the Army's communications, radar, and electronics — technology that reshaped how twentieth-century wars were fought. Its Avenue of Memories lined a fort roadway with 117 trees and monuments, each honoring a Signal Corps soldier who died in action during World War II. After the historic post was decommissioned, those monuments were preserved rather than lost, and in November 2025 all 117 were rededicated together in Cowan Park.
Karl Jansky Radio Astronomy Site
Holmdel Township, NJ
In 1932, Bell Labs engineer Karl Jansky, working at this Holmdel site, detected radio waves coming from beyond the Earth while investigating sources of static on radio calls. Tracing the mysterious hiss to the sky, he found it came from the direction of the Milky Way's center — the first radio emissions ever recorded from space. From this quiet New Jersey field grew the entirely new science of radio astronomy.
Thomas Edison
New York, NY · est. 1938
On an April night in 1896, a New York vaudeville house called Koster & Bial's Music Hall hosted something audiences had never seen: images that moved on a screen for a paying crowd. Using Thomas Edison's Vitascope projector, the program threw flickering scenes larger than life before a Broadway audience, marking the American debut of projected motion pictures. The tablet was later affixed by the motion-picture industry itself, honoring the spot where its business was, in effect, born.

On January 7, 1943, the Serbian-American inventor Nikola Tesla died in New York City at the age of eighty-six. A pioneer of alternating-current electricity, Tesla's discoveries in the field of AC power helped carry the United States and the world into the modern industrial age. This marker was placed in 1977 by the Yugoslav-American Bicentennial Committee.
