You’ve probably seen the grainy, black-and-white image of three small boys huddled together for warmth on a stone grate. They look like they're sleeping, but they’re actually just trying to survive the night in a New York City alleyway. That image—and dozens like it—changed everything. When Jacob Riis photos How the Other Half Lives hit the scene in 1890, it didn’t just inform people. It basically slapped them in the face.
Before Riis, the "other half" of New York was invisible. If you lived in a brownstone on the Upper East Side, you honestly had no clue that people were living twelve-to-a-room in windowless basements just a few miles south. Riis changed the game by using a brand-new, terrifyingly loud technology: flash powder. He would literally burst into dark, cramped tenements, set off a blinding explosion of magnesium light, and capture the raw, unedited misery before the occupants could even blink.
It was invasive. It was messy. And it was exactly what the world needed to see.
The Man Who Couldn't Forget
Jacob Riis wasn't some high-society artist looking for a "gritty" project. He was a Danish immigrant who arrived in New York in 1870 with almost nothing. He spent years sleeping in police lodging houses—which were basically filthy, vermin-infested pits—and eating whatever he could find. He knew what it felt like to be ignored by a city that only cared about the Gilded Age's gold plating.
Eventually, he landed a job as a police reporter for the New York Tribune. His beat? The Lower East Side. Specifically, places like Mulberry Bend, where the death rate for infants was a staggering one in ten.
Riis wrote thousands of words about the filth. Nobody cared. He realized that people could ignore a paragraph, but they couldn't ignore a face. "My negatives, still dripping from the dark-room, came to reinforce [my words]," he later said. He wasn't interested in "art." He wanted evidence.

Why Flash Photography Changed the World
Back in the late 1880s, photography was a slow, outdoor business. You needed sunlight. If you tried to take a picture inside a dark tenement, you’d get nothing but a black rectangle. Then came Blitzlichtpulver—magnesium flash powder.
It was a total game-changer for Jacob Riis photos How the Other Half Lives. Here is how it basically worked:
- Riis would carry a heavy wooden camera and a tripod into a dark alley.
- He’d find a group of people, often sleeping or working.
- He would pour flash powder onto a pan and ignite it.
- Boom. A blinding flash, a cloud of acrid smoke, and a permanent record of the "Other Half."
Sometimes he’d accidentally set things on fire. He nearly blinded himself at least once. He even set two buildings on fire during his career. But the results were undeniable. For the first time, the middle class saw the "dens" and "dives" of New York in startling, high-contrast detail.
The Dark Side of the Lens
Honestly, we have to talk about the ethics here. Riis wasn't exactly asking for consent. He often barged into people's private homes—or what passed for homes—at 2:00 AM. Modern critics like Maren Stange have pointed out that his work was kinda voyeuristic. He treated his subjects like specimens in a lab rather than people with agency.
He also brought a lot of his own biases to the work. He was a product of his time, and his writing is filled with ethnic stereotypes that make modern readers cringe. He had very specific, often harsh views on Jewish, Italian, and Irish immigrants, judging them based on how well they "assimilated" to his idea of American values.

The Photos That Broke the System
When How the Other Half Lives was published as a book in 1890, it became an instant bestseller. It featured 17 halftone photographs and 19 drawings based on his photos. It reached the hands of a young, ambitious man named Theodore Roosevelt.
Roosevelt was so moved that he tracked Riis down at his office and left a note: "I have read your book, and I have come to help."
Together, they started tearing things down. They abolished the horrific police lodging houses. They pushed for the Tenement House Act of 1901, which finally mandated things we take for granted today:
- Every room must have a window for light and air.
- Proper fire escapes are mandatory.
- Indoor toilets (instead of outdoor privies shared by 20 families).
- Improved ventilation to stop the spread of tuberculosis.
Mapping the Misery
Riis didn't just photograph people; he photographed the architecture of poverty. He focused on places like "Bandit's Roost" and "Hell's Kitchen." He showed that the buildings themselves were the problem. The "dumbbell tenements" were designed to pack as many people in as possible, creating air shafts that acted like chimneys during fires and sewers for garbage during the rest of the time.
Because of Riis, the city eventually razed Mulberry Bend, one of the worst slums in the world, and replaced it with a park. He believed that if you gave children a place to play that wasn't a gutter, they wouldn't grow up to be criminals. It was a radical idea at the time.

The Long-Term Impact
You can see the DNA of Jacob Riis photos How the Other Half Lives in almost every piece of investigative journalism today. He pioneered the "muckraking" style that would later be used by Lewis Hine to end child labor and Dorothea Lange to document the Great Depression.
He proved that a camera is a weapon.
Even now, over 130 years later, these photos haven't lost their power. When you look at his shot of the "Bohemian Cigarmakers" working in their cramped apartment, you feel the heat and the smell of tobacco. It's not just a history lesson. It's a reminder that society is only as healthy as its most vulnerable members.
What You Can Learn From Riis Today
If you’re interested in social justice, photography, or just how cities work, Riis’s work offers a massive blueprint. It’s not just about taking a "sad" photo; it’s about using that photo to demand a specific policy change.
Practical Steps to Explore This History:
- Visit the Source: The Museum of the City of New York holds the largest collection of Riis’s original glass plate negatives. Seeing them in person is a completely different experience than seeing a compressed JPEG online.
- Read the Text: Don't just look at the pictures. Read the book. It's uncomfortable and biased, but it shows you exactly how he used rhetoric to manipulate his 1890s audience into caring.
- Check the Geography: Next time you're in Manhattan, walk through Columbus Park. That used to be Mulberry Bend. Look at the space and try to imagine 300,000 people per square mile living there.
- Compare Modern Issues: Look at current photojournalism regarding the housing crisis or migrant shelters. Ask yourself: Are we still using the same "surveillance" techniques Riis used? Is it still effective?
Jacob Riis didn't just take pictures. He made it impossible for the "Other Half" to remain a secret. He showed that while the camera might not tell the whole truth, it tells a truth that's very hard to ignore.
Actionable Insight: To truly understand the impact of social documentary, compare Riis's work to the Lewis Hine photographs of the 1910s. While Riis often "caught" his subjects by surprise, Hine worked to build rapport, showing a shift in how journalists viewed the dignity of the poor. Reviewing both side-by-side reveals how the ethics of photography evolved from "evidence gathering" to "humanizing the subject."
