They look almost peaceful now. Tucked behind thick glass in the Rice Gallery at the Field Museum of Natural History, the two African lions in the Chicago museum don't exactly look like the monsters that halted the British Empire’s railroad ambitions in 1898. They’re a bit smaller than you’d expect. No manes. No Hollywood roar. Just a pair of taxidermied cats that happens to have eaten about 35 people—though if you ask the guy who shot them, that number was closer to 135.
It's weird.
Most people walk past the dioramas in the Field Museum and see "nature." They see a frozen moment of the Serengeti or a preserved slice of the Arctic. But the Lions of Tsavo are different. They aren't just specimens; they are historical villains. They represent a specific, terrifying glitch in the relationship between humans and the natural world.
What Really Happened in Tsavo?
In the late 19th century, the British were busy building a bridge over the Tsavo River in what is now Kenya. It was a massive project, part of the "Uganda Railway." Then the screaming started. For nine months, two man-eating lions hunted the workers. These weren't your typical "old and sick" predators looking for an easy meal. These were apex hunters that developed a specific, terrifying taste for human flesh.
They were relentless.
Lt. Col. John Henry Patterson, the engineer in charge, eventually shot them, but not before the project was nearly abandoned because the workers were—rightfully—convinced the lions were demons in feline form. Patterson kept the skins as rugs for twenty-five years. Seriously. He finally sold them to the Field Museum in 1924 for $5,000, which was a chunk of change back then.

Why the Maneless Look?
If you’ve spent any time looking at African lions in the Chicago museum, you’ve probably noticed something "off" about the Tsavo pair. They don’t have those majestic, flowing manes we see in The Lion King.
There's a reason for that.
It’s not because they were young. It’s because Tsavo is incredibly hot and covered in thorny brush. Having a giant, thick mane in that environment is basically like wearing a wool parka in a sauna while trying to run through a briar patch. Evolution realized that manes were a liability in the Kenyan scrub, so the lions there just... stopped growing them. It makes them look sleeker, more reptilian, and honestly, a lot more intimidating when you realize they could slip through the darkness without a giant hair-halo snagging on every branch.
The Science of Why They Ate People
For a long time, the legend of the Tsavo lions was just that—a legend. People thought Patterson was exaggerating his "Ghost" and "Darkness" story to sell books. But in recent years, researchers at the Field Museum, including Dr. Bruce Patterson (no relation to the Colonel), have used modern science to peek into the lives of these cats.
They looked at the isotopes in the lions' hair and teeth.

The results were fascinating. By analyzing the chemical signatures of what the lions ate in their final months, scientists confirmed that one lion had eaten about 11 humans, and the other had consumed about 24. While that's lower than the Colonel's claim of 135, it’s still a staggering amount of human predation.
But why did they do it?
- Dental Pain: One of the lions had a massive abscess at the root of its canine tooth. Imagine a toothache so bad it makes it impossible to take down a 600-pound zebra. Humans are soft. We’re slow. We are, unfortunately, the "soft serve" of the animal kingdom for a lion with a broken jaw.
- Environmental Collapse: An outbreak of rinderpest (a cattle plague) had wiped out the lions' usual prey.
- The Slave Trade Path: The Tsavo River was a historical route for slave caravans. It’s a grim reality, but lions in that area had likely been scavenging on deceased humans for generations before the railway arrived.
Visiting the African Lions in the Chicago Museum Today
When you stand in front of the display today, the lighting is dim. It’s intentional. The museum wants you to feel that 1898 atmosphere. Most visitors don't realize that the lions were actually "reconstructed" from the rugs Patterson sold. If you look closely at the mounts, you can see the scars and the patches where the fur was worn down from years of being walked on in the Colonel's house.
It’s a bizarre mix of history, biology, and true crime.
The Field Museum doesn't just treat them as "scary monsters" anymore. They are a case study in human-wildlife conflict. As human populations expand into wild territories, the story of Tsavo repeats itself in smaller ways across the globe.

Getting the Most Out of Your Visit
If you’re planning to see the African lions in the Chicago museum, don’t just snap a photo and move on to the T-Rex.
- Check the teeth. Look for the dental damage on the lion on the left. It’s the smoking gun of the whole "man-eater" saga.
- Look at the size. They aren't as big as the lions you see in zoos. They are built for endurance and stealth in thick brush.
- Read the journals. The museum often displays excerpts from Patterson’s diary nearby. Take the "heroic" tone with a grain of salt—he was definitely trying to look like a Victorian action hero.
The reality of these animals is far more complex than a campfire ghost story. They were hungry, injured animals in a changing world. They were also efficient killers that effectively stopped a global superpower's infrastructure project for months.
Actionable Steps for Your Museum Trip
If you want to dive deeper than just a casual walk-through, here is how you should handle your visit to the Field Museum's African exhibits:
- Go Early: The Rice Gallery is a "high-traffic" area. If you want to actually see the dental pathology without someone's toddler blocking your view, get there right when the doors open at 9:00 AM.
- Pair with the Movie: Watch The Ghost and the Darkness (the 1996 film with Michael Douglas) before you go. It’s not 100% historically accurate, but it gives you a visceral sense of the terror those workers felt. Just remember: the real lions didn't have manes!
- Explore the Lab: Visit the "Grainger Science Hub" on the upper floor. Sometimes they have Lion-related specimens out for people to see up close, and you can talk to the educators about current conservation efforts in the Tsavo region.
- Consider the Context: After seeing the lions, walk over to the "Ancient Egypt" exhibit. Think about how the relationship between humans and big cats has shifted from "Gods" to "Pests" to "Conservation Priorities" over the last 5,000 years.
The Lions of Tsavo remain the most popular "non-dinosaur" attraction at the museum for a reason. They represent the thin line between the civilized world we built and the raw, unforgiving reality of the wild. They aren't just skins and bones; they are a reminder that for a brief moment in 1898, the lions were winning.
To get the full experience, head to the Field Museum located at 1400 S DuSable Lake Shore Dr. If you're a Chicago resident, check their calendar for "Free Days," but be warned—the lions get very crowded when the price is right. For the best view, visit on a Tuesday or Wednesday afternoon when the school groups have mostly cleared out.
Stand there. Be quiet. Look into those glass eyes and realize that a century ago, those eyes were looking back at us as nothing more than a meal.
