Did A Cow Really Start The Great Chicago Fire?

One of America’s most famous stories involves a cow kicking over a lantern, causing one of the deadliest fires in the country. This poor cow has been viewed as the cause of the Great Chicago Fire…without any actual evidence. Can I clear this cow’s name by the end of this article? Let’s find out.

On October 8, 1871, a fire started on Patrick and Catherine O’Leary’s property at 137 DeKoven Street in Chicago. It’s unclear whether the fire started in or near their barn, but one thing was clear: the O’Leary family was suddenly at the center of a crime scene.

Here’s how the story goes. Catherine O’Leary was milking her cow. At some point, the animal knocked over a kerosene lantern, which in turn set the hay on fire. And well…the rest is history. Now this would be quite the scandal if it were true. However, historians have found no evidence that Catherine was milking her cow. In fact, Catherine herself testified under oath that she was in bed when the fire started.

One reason why historians don’t believe the cow story is that a journalist claimed to have made the whole thing up. Yep, journalist Michael Ahern confessed decades later that he thought making up some dramatic story about the fire would help the newspaper sell better. Of course, that only proves nobody had evidence for the cow. It doesn’t prove what did start the fire, which is why people are still arguing about that barn.

Why did a journalist feel the need to come up with such a story? Well, in the 1870s, newspapers competed with each other, much like streaming services do today. So, to get an edge on other papers, Ahern thought up the cow story, hoping his tale would attract readers and push his paper to the top.

At the time of the fire, Irish immigrants faced prejudice in America. Because Catherine O’Leary was an Irish Catholic immigrant, she became an easy target. People saw her as poor and irresponsible, fully believing that she would be careless enough to cause the whole disaster.

Poor Catherine and her family faced intense public scrutiny once the accusations spread, becoming a target for a city desperate to blame someone.

After the dust had settled, Chicago officials started investigating, and what they found, or didn’t find, probably upset a lot of people. They concluded that there was no evidence that Catherine or her cow caused the fire. However, they had no idea what or who did.

If Catherine and her cow weren’t to blame for the fire, then who was? What really happened that day? As you can imagine, many theories have emerged. Some people think that neighborhood boys were gambling in the barn and accidentally started the fire. Others believe that someone must have been smoking inside the barn. One of the strangest theories? A meteor shower, though scientists quickly rejected that possibility.

Enter Daniel “Peg Leg” Sullivan, one of the first people to notice the fire. He said that when he noticed the flames, he ran into the O’Leary barn to rescue their animals. Despite being one of the first eyewitnesses, he could not say what caused the fire. In fact, some people believe that it was Sullivan who accidentally started the fire while in or near the barn that night.

Just to add to how fabricated the cow story was, that famous lantern the cow supposedly kicked over? You know, the one that caused the fire? It might not even have existed. Yep, historians can’t confirm that there was a lantern.

Despite the lack of evidence, something about the cow story stuck, and the story is still being spread today. For years, American schoolchildren have been learning a rhyme about “Mrs. O’Leary’s cow.” The song goes like this: “Late one night, when we were all in bed, Old Mother Leary left a lantern in the shed. And when the cow kicked it over, she winked her eye and said, ‘There’ll be a HOT time on the old town tonight.’ FIRE, FIRE, FIRE!” It really does seem that many children’s rhymes are about tragedies.

It wasn’t just children singing about the myth; the people of Chicago actively kept the story alive through museums, souvenirs, and public events. They saw it as another interesting story they could impress tourists with.

Catherine O’Leary wasn’t a fan of her newfound notoriety. With all eyes on her, she could’ve spent the rest of her life clearing her name, but she didn’t. Instead, she chose not to speak publicly about the accusations for the rest of her life.

One plausible theory is that the fire was inevitable. Months of drought, along with the fact that much of Chicago was built of wood, meant it was only a matter of time for disaster to strike. Add some strong winds and any small spark could’ve triggered the deadly fire.

A big reason why so many people clung to the cow story was to avoid the real issues Chicago faced. At the end of the day, it didn’t matter how the fire was started. A lack of firefighting resources, poor building practices, wooden structures, and dry weather all contributed to the size and severity of the fire.

It’s been over 150 years since the fire that killed approximately 300 people, destroyed 17,000 structures, and left more than 100,000 residents homeless. Over the years, there have been several conflicting theories, but the fire remains one of America’s greatest mysteries.

It took some time, but in 1997, the Chicago City Council finally cleared Catherine O’Leary’s name. Both she and her cow were cleared of any responsibility for starting the fire. Sadly, Catherine wasn’t alive to witness her name being cleared.

Sadly, Catherine O’Leary will remain an iconic historical figure, but not for the reasons anyone hopes. Little is actually known about who she was as a person. Sure, she was a wife and mother who lived in a modest cottage in the city and had cows. I wish we could’ve known more about her story. The real story.

The myth of Catherine O’Leary and her cow proves that one good story can change history. Despite all the proof that a cow didn’t start the fire, people decided that the story was too perfect, so they rewrote history. Sometimes a lie is far more entertaining and easier to grasp than the truth.
