The title of the oldest person ever is a distinction that belongs to a woman named Jeanne Calment, who lived in France during the 19th and 20th centuries. Her life story is a fascinating glimpse into the past, as she was born in 1875, just a few decades after the American Civil War, and lived to see the dawn of the internet age before her death in 1997. Calment's journey and her record have captivated demographers and the general public alike, inspiring discussions about the upper limits of human lifespan and the factors contributing to exceptional longevity.
The Life of Jeanne Calment
Jeanne Louise Calment was born on February 21, 1875, in Arles, France. Her long life meant she witnessed an extraordinary sweep of history. She met Vincent van Gogh as a young woman when he visited her family's shop. Over her 122-year life, she experienced both World Wars, numerous technological revolutions, and dramatic societal changes.
Calment came from a bourgeois family, which afforded her a life of relative ease. She never had to work, and she pursued hobbies like tennis, bicycling, and roller-skating well into her later years. Her famously relaxed approach to life was summed up in her quote, “If you can’t do anything about it, don’t worry about it”. Her unique lifestyle and diet included smoking until she was 119 and a fondness for chocolate, which defied typical health advice. However, experts suggest her exceptional lifespan was mostly a matter of chance and a certain immunity to stress.
The Age Verification Process
Verifying the age of supercentenarians, individuals who live to 110 or older, is a meticulous and complex process. For a record to be official, it must be validated by organizations like the Gerontology Research Group (GRG) and Guinness World Records, which examine a wide range of documents to corroborate an individual's claimed birthdate. The evidence includes:
- Birth certificates or parish records: These foundational documents confirm the date of birth and identity.
- Census records: Researchers compare census data over the decades to track the individual's presence and age within their family and community.
- Marriage and death certificates: These records provide additional data points and context for a person's life history.
- Notary and other legal documents: For Calment, a life estate contract she signed at age 90 provided compelling legal evidence of her existence at that point in time.
- Independent testimony and interviews: Eyewitness accounts and the individual's own recollections are also factored in, though weighed against documentary evidence.
For Jeanne Calment, a team of French demographers and gerontologists conducted an extensive investigation spanning more than a year to authenticate her age. They examined decades of census data and other public and private records to build an iron-clad case for her incredible longevity. This rigorous process is what makes her record so widely accepted, despite some later, largely discredited, claims of fraud.
The Record and Other Supercentenarians
While Jeanne Calment holds the all-time record, other individuals have also achieved remarkable lifespans. The list below highlights some of the most notable supercentenarians whose ages have been independently verified.
| Name | Country | Age at Death | All-Time Rank |
|---|---|---|---|
| Jeanne Calment | France | 122 years, 164 days | 1 |
| Kane Tanaka | Japan | 119 years, 107 days | 2 |
| Sarah Knauss | United States | 119 years, 97 days | 3 |
| Lucile Randon | France | 118 years, 340 days | 4 |
| Nabi Tajima | Japan | 117 years, 260 days | 5 |
| Jiroemon Kimura | Japan | 116 years, 54 days | Oldest Man |
Living vs. All-Time Record Holders
It's important to distinguish between the oldest person ever and the oldest person currently alive. As of September 2025, the oldest living person is Ethel Caterham of the United Kingdom, who was born on August 21, 1909. The title passes from person to person, but the all-time record set by Jeanne Calment has stood for nearly three decades.
Factors in Reaching Extreme Old Age
While Calment's casual lifestyle might suggest otherwise, researchers have long studied supercentenarians to identify common traits that could explain their exceptional longevity. Some of the potential factors include:
- Genetics: A significant portion of longevity is believed to be hereditary. Calment's own family had a history of above-average lifespans.
- Lifestyle and Diet: While not universally applicable, a healthy and moderate lifestyle is generally linked to longer life expectancy. Many record-holders lead active, socially engaged lives.
- Resilience to Stress: Some researchers point to Calment's calm and stress-immune personality as a potential contributing factor to her long life.
- Random Chance: Despite all the research, a large element of pure luck and extraordinary statistical rarity is often acknowledged as a factor in reaching such extreme ages.
Conclusion
Jeanne Calment remains the benchmark for the human lifespan, having lived an incredible 122 years and 164 days. Her record, rigorously verified by gerontologists, has stood for decades, solidifying her place in history as the oldest person whose age could be independently confirmed. While the identity of the world's oldest living person changes, Calment's story continues to fascinate and inspire, pushing researchers to better understand the science behind extreme longevity. Whether through genetics, lifestyle, or sheer luck, her life represents the extraordinary potential of the human experience.
The Longevity Gene: Is it Real?
Jeanne Calment came from a family with a history of long life, suggesting a possible genetic link to her own extraordinary age. Scientists believe that genetics do play a role, with estimates suggesting that up to 25% of the variation in human lifespan is linked to inherited factors. Studies of supercentenarians often involve examining their genomes for unique genetic markers and variations that might provide insights into delayed aging and resilience against age-related diseases. For instance, certain genes related to metabolism and cellular repair are being studied for their potential connection to longer lifespans. However, the exact genetic blueprint for reaching 120 or beyond remains a complex area of research, with environmental and lifestyle factors still playing a crucial role. The interplay between nature and nurture is what ultimately determines who reaches the pinnacle of longevity.
