Walk past the Smithsonian Institution Building—the "Castle"—and you can't miss him. He’s bronze. He’s huge. He’s wearing a heavy academic robe that looks like it weighs about fifty pounds. This is the Professor Joseph Henry statue, and if you’re like most tourists, you probably glance at it and keep walking toward the Air and Space Museum.
That’s a mistake.
Most people think of statues as dead weight. Just some dusty guy from the 1800s. But this specific monument, designed by the legendary William Wetmore Story, represents a massive turning point in how America treats science. Joseph Henry wasn't just a "professor." He was the first Secretary of the Smithsonian. He was the guy who basically invented the telegraph before Samuel Morse got the patent. He was the original American science influencer, and he didn't even want this statue to exist.
The Reluctant Monument: Why Henry Hated the Idea
It’s kind of ironic. Joseph Henry was a man of absolute modesty. He believed that scientific pursuit should be its own reward, and he famously refused to patent his discoveries because he thought they belonged to the public. When he died in 1878, Congress almost immediately started talking about a monument.
Henry would have hated it.
He spent his career fighting against the idea of the Smithsonian being a "cabinet of curiosities" or a place for vanity projects. He wanted it to be a powerhouse of "increase and diffusion of knowledge." Yet, here we are. In 1881, the federal government dropped $15,000—a fortune back then—to commission this bronze figure.
If you look closely at the Professor Joseph Henry statue, you’ll see he’s standing on a pedestal of Quincy granite. He looks serious. Almost annoyed. Maybe he’s annoyed that he’s stuck outside in the D.C. humidity forever. The statue was unveiled on April 19, 1883. It wasn't just a small gathering; we're talking about the President of the United States, the Cabinet, and the Supreme Court all showing up. Why? Because in the late 19th century, Henry was the closest thing America had to a secular saint.
A Masterpiece by William Wetmore Story
Let's talk about the artist. You’ve probably seen William Wetmore Story’s work without realizing it. He was an American living in Rome, part of that elite circle of expats who thought Europe was the only place to get a real education. Story didn't just make a "likeness." He tried to capture the intellectual weight of the man.

The bronze was cast in Rome and shipped across the Atlantic. It’s over nine feet tall.
If you’re standing in front of it, check out the robes. They aren’t just "clothes." They represent his status as a scholar and his connection to Princeton (then the College of New Jersey). Story used a neoclassical style that was very popular at the time, but he added a level of physical realism in the face that was rare. He used photographs and a life mask to make sure the nose and the brow were exactly right.
One detail people miss: the hands. Look at how they hold the gown. It’s not a relaxed pose. It’s the pose of a man about to step forward. It captures that transition between the "Castle" behind him—which he helped build into a world-class institution—and the future of American research.
Where exactly is it?
You’ll find it on the north side of the Smithsonian Castle, facing the National Mall.
- Address: 1000 Jefferson Dr SW, Washington, DC 20560.
- Orientation: He’s looking north toward the Washington Monument and the White House.
- Accessibility: It’s in a public plaza. You can walk right up to it. No tickets required.
What Most People Get Wrong About Joseph Henry
You’ve probably heard of the "Henry" as a unit of self-inductance. That’s him. But the common misconception is that he was just a Smithsonian administrator.
Honestly, the guy was a beast in the lab. Before he ever moved to D.C., he was at the Albany Academy and then Princeton, playing with magnets. He discovered self-induction independently of Michael Faraday. He built the most powerful electromagnets in the world. He basically figured out how to send an electric signal over a mile of wire to ring a bell—the literal foundation of the telegraph.
The Professor Joseph Henry statue stands as a reminder that the Smithsonian didn't start as a museum for Dorothy’s red slippers or the Apollo 11 capsule. It started as a research lab. Henry used to fly kites from the towers of the Castle to study electricity in the atmosphere. He started the first national weather observation network, which eventually became the National Weather Service.

When you look at that statue, you aren't looking at a curator. You're looking at a physicist who redefined how the United States government interacts with the hard sciences.
The Controversy of the Location
Believe it or not, the statue hasn't always been at peace with its surroundings. Throughout the 20th century, as the National Mall was redesigned, there were constant debates about where to put these "great men" monuments.
Some urban planners wanted to move the Professor Joseph Henry statue further away to keep the Mall "clean" and open. But the Smithsonian fought back. They argued that Henry and the Castle are inseparable. He lived in the Castle. His kids grew up there. He died there. Moving the statue would be like moving a gravestone.
In fact, Henry is buried nearby, but not under the statue. He’s at Oak Hill Cemetery in Georgetown. But for all intents and purposes, this bronze figure is his primary residence in the public imagination.
How to Actually "See" the Statue
If you’re visiting, don’t just take a selfie and leave. Do this instead:
Start at the base and read the inscriptions. Notice the lack of flashy titles. It’s simple. Then, walk around to the side. Look at the way the sunlight hits the bronze in the late afternoon. Because it faces north, the statue is often in shadow during the middle of the day, which makes it look dark and imposing. But around 4:00 PM in the summer, the light wraps around the Castle and hits the bronze, bringing out the greenish patina that has developed over 140 years.
That patina? It’s a chemical reaction. Copper in the bronze reacting with the D.C. rain. Henry, the chemist and physicist, would have found that fascinating. He probably would have written a paper on the rate of oxidation.

Specific details to look for:
- The Footing: Notice how he isn't standing flat. One foot is slightly forward. It’s a "contrapposto" stance, an ancient Greek technique to make statues look like they have internal life.
- The Pedestal: The granite base is massive. It’s meant to make you feel small. It symbolizes the "solid foundation" of the Smithsonian.
- The Gaze: He isn't looking at you. He's looking past you. He's looking toward the horizon, which was Story’s way of saying Henry was a visionary.
The Statue in Modern Times
In 2026, the National Mall is a crowded place. There are monuments for everything now. It’s easy for a 19th-century guy in a robe to get lost in the shuffle of the Hirshhorn’s modern art or the grand scale of the African American History and Culture Museum.
But the Professor Joseph Henry statue remains the "anchor." It reminds us that before there was a "Space Race" or a "Digital Age," there was a guy in a drafty red stone building who believed that the government should pay for people to sit in rooms and think about how the world works.
He was the one who insisted that the Smithsonian shouldn't charge admission. He wanted it to be free. Every time you walk into a Smithsonian museum today without opening your wallet, you’re experiencing Joseph Henry’s legacy. The statue is just the physical "thank you" note for that.
Actionable Insights for Your Visit
If you’re planning a trip to see the Professor Joseph Henry statue, keep these points in mind to get the most out of the experience:
- Visit at Twilight: The lighting on the north side of the Castle is most dramatic just before sunset. The bronze takes on a much deeper, more soulful tone than it does in the harsh midday sun.
- Pair it with the Castle Tour: Don’t just look at the statue. Go inside the Smithsonian Castle (it's right behind him). There’s a crypt for James Smithson and exhibits on Henry’s early experiments. Seeing his actual tools makes the statue feel more like a man and less like a myth.
- Check the Enid A. Haupt Garden: Just behind the Castle is a stunning 4-acre garden. It’s the perfect place to sit and read about the history of the telegraph or early American science while staying in the "Henry" headspace.
- Educational Angle: If you have kids, ask them to find the "magnets" in the museum exhibits nearby. Remind them that the guy in the statue made those possible. It’s a great way to bridge the gap between "boring old statue" and "cool science."
- Photography Tip: For the best shot, stand near the Jefferson Drive curb and use a portrait lens (85mm is best). This compresses the background, making the Professor Joseph Henry statue pop against the iconic red sandstone of the Castle.
The monument isn't just a piece of metal. It's a tribute to the idea that knowledge shouldn't be hoarded. It should be shared. Even if Henry himself was too humble to want his face cast in bronze, the statue serves a purpose: it forces us to stop for a second and remember that the modern world was built by people who were obsessed with the "why" of things.
Next time you're in D.C., give the Professor a nod. He earned it.
