Jeanne Calment died on the age of 122 years and 164 days in 1997, setting a document because the world's most long-lived individual that’s nonetheless unsurpassed.

The aged lady used to joke that God will need to have forgotten about her.

However Russian mathematician Nikolai Zak just isn’t satisfied by her story.

In collaboration with gerontologist Valery Novoselov, I’ve spent months analyzing biographies of Jeanne Calment in addition to her interviews and pictures, witness testimony and the general public information of town of Arles in southern France the place she lived.

"Analyzing all these supplies led me to conclude that Jeanne Calment's daughter Yvonne assumed her mom's identification," Zak advised AFP.

Zak, a member of the Moscow Society of Naturalists at Moscow State College, lately revealed his report referred to as "Jeanne Calment: the Secret of Longevity" on ResearchGate, a portal connecting scientists all over the world.

Whereas opponents have slammed the report, some scientists have welcomed it and harassed the necessity for nearer checks into longevity information.

Zak means that in 1934 it was not Calment's daughter Yvonne who died of pleurisy, as official information say, however Jeanne Calment herself. Yvonne then took on her mom's identification with a purpose to keep away from paying inheritance tax.

If this is the case, the girl who died in 1997 was in reality Yvonne, and he or she was aged simply 99.

The Russian researcher factors to discrepancies between bodily traits listed on Calment's identification card from the 1930s and her look in later years.

Name for exhuming our bodies

The cardboard offers her eye coloration as darkish and her peak as 1 meter, 52 centimetres and describes her brow as low – all that along with her later look.

"As a physician I all the time had doubts about her age," stated Novoselov, who heads the gerontology part of the Moscow Society of Naturalists.

"The state of her muscle system was completely different from that of her contemporaries, She might sit up with none assist, She had no indicators of dementia."

After Calment's loss of life, scientists expressed remorse that no post-mortem was held to seek out the explanations for his or her distinctive longevity.

She used to speak of having fun with chocolate and port and would smoke an occasional cigarette earlier than her well being deteriorated.

Fuelling suspicions, Calment ordered a few of her outdated pictures to be burnt when she grew to become well-known, the Russian say.

Interviewed by AFP, French demographer and gerontologist Jean-Marie Robine, who took half in authenticating Calment's age for Guinness World Information, stated he had "by no means had any doubt concerning the authenticity of the paperwork" of the girl.

I’ve slammed the Russian report, saying it "by no means examines the information in favor of the authenticity of the longevity of Madame Calment" and "seems to

me to be defamatory towards her household. "

The main of Arles on the time of Calment's loss of life, Michel Vauzelle, stated that the Russians' idea was "fully inconceivable and ridiculous" since Calment was monitored by a lot of medical doctors.

However others welcomed the analysis.

"The concept of ​​the assumed identification had already been thought-about by these validating (the declare) and I frequently invited demographers to carry onto this speculation," stated Nicolas Brouard, analysis director at France's Nationwide Institute of Demographic Etudes (INED).

"It's good that Nikolai Zak has carried out analysis that’s unbiased and covers the identical space of ​​analysis.

an argument in favor of exhuming the our bodies of Jeanne and Yvonne Calment, "he stated.

DNA testing would be capable of lastly settle the controversy, he stated.

'Nationwide heroine'

Belgian demographer Michel Poulain, of the College of Louvain, welcomed what he referred to as "take away an in depth investigation" that he stated exhibits the necessity for additional scientific analysis "to validate the distinctive age of those supercentenarians" – these older than 110.

"The chance of an inaccurate age will increase exponentially with presumed age," he stated.

Zak got here up with the concept of ​​investigating Calment's life whereas making a mathematical mannequin of the lifespan of supercentenarians.

"The extra I searched, the extra contradictions I discovered," he stated.

In a e book revealed in 1997 titled "Insurance coverage and its secrets and techniques", I discovered a brief passage about Calment that supported the concept her daughter took on her identification.

The e book's writer, Jean-Pierre Daniel, wrote that an insurance coverage researcher wanting right into a life annuity taken by Jeanne Calment had already concluded that fraud passed off.

"However on the time Jeanne Calment was already thought-about a nationwide heroine." That official requested his bosses about it they usually advised him to maintain on paying off the annuity. "There was no query of making a scandal over the doyenne of the French," advised AFP.

Gerontologist Novoselov argues that query marks over Calment's true age are damaging to his subject since "for gerontologists, Jeanne Calment is an emblem." Her identify is cited in all of the research … the chessboard. "

Members of Calm's prolonged household didn’t reply to requests for remark from AFP.

If Calment's document was canceled, the brand new record-holder can be American Sarah Knauss, who died at 119 in 1999.
