Big Bertha wasn’t just a cow—she was a legend. Born on St. Patrick’s Day in 1945 in County Kerry, Ireland, Bertha’s life was one of longevity, generosity, and an undeniable charm that made her a beloved figure far beyond her local farm. From breaking world records to raising tens of thousands for cancer research, Big Bertha’s story is udderly unforgettable.
A Record-Breaking Life of Moo-sive Proportions
Big Bertha didn’t just live a long life—she lived the longest life of any cow ever recorded. She passed away on New Year’s Eve in 1993, just three months shy of her 49th birthday. Her incredible lifespan earned her a Guinness World Record for being the oldest cow in the world, an accolade that brought her into the global spotlight.
But that’s not all. Bertha also earned a second Guinness World Record for lifetime breeding, having birthed an astounding 39 calves over the course of her life. Her exceptional fertility made her a marvel in the agricultural world and a cornerstone of her owner Jerome O’Leary’s herd.
From Local Cow to Fundraising Icon
Bertha’s fame wasn’t just about her age or her calves—it was about what she did with her celebrity. O’Leary, her owner and lifelong friend, regularly brought her to local fairs, parades, and charity events, including the annual St. Patrick’s Day parade in Sneem, where she often led the procession to much applause.
Through her many public appearances, Bertha helped raise over $75,000 (roughly £50,000–£60,000 at the time) for cancer research and local charities. Though exact figures vary, her impact is unquestioned. She became a furry fundraiser, moo-ving hearts and wallets in equal measure.
A Cow With Character (and Maybe a Taste for Whiskey)
Bertha wasn’t just special—she had personality. According to her owner, she enjoyed the occasional shot of whiskey before parades to “steady her nerves.” While there’s no independent verification of her whiskey-drinking habit, the story adds a charming layer to her already colorful legacy. Locals fondly remember her placid nature, intelligence, and surprising showmanship.
Her breed, the Droimeann, is known for being hardy, intelligent, and easygoing—traits Bertha exemplified every day of her life. She was known to play up for crowds and seemed to enjoy the spotlight, endearing her to everyone she met.
A Wake Fit for Royalty—and a Legacy That Lives On
When Big Bertha passed away in 1993, she didn’t fade quietly into the night. Her wake was held at the Blackwater Tavern in County Kerry, where friends, locals, and admirers gathered to celebrate her extraordinary life. Stories were shared, songs were sung, and glasses were raised in honor of a cow that had become more than livestock—she was family.
Even in death, Bertha continued to inspire. Her body was preserved and is now on display in Kerry, serving as a lasting tribute to her legacy. Her spirit also lives on in unexpected ways—like in Bertha’s Revenge Gin, named in her honor and celebrating the gentle power of Ireland’s farming heritage.
Conclusion: A Cow Like No Other
Big Bertha was more than a world record holder. She was a symbol of resilience, community, and the joy that animals bring into our lives. Her contributions to science, charity, and culture prove that even a cow can change the world—one parade, one calf, and one charitable moo at a time.
In the words of her fans, Bertha wasn’t just big—she was monumental.
