In January 2014, an 88-year-old French cardiologist named Dr. Marthe Gautier was about to receive a medal and give a talk at a genetics conference in Bordeaux. She planned to tell the story of a discovery she had made 56 years earlier -- one that changed our understanding of Down syndrome forever. Hours before she was scheduled to speak, two bailiffs arrived with a court order and recording equipment, sent by the Jérôme Lejeune Foundation -- named after the male colleague who had taken credit for her work.
The bailiffs warned that if she said anything that "tarnished" Lejeune's memory, the foundation would have grounds for legal action. The conference organizers panicked and canceled her talk. They handed Gautier her medal in a private ceremony at her hotel room. Then they lied to the press, telling them she had been too ill to appear.
The stress was so severe that the 88-year-old lost all of her hair. She wore a wig for the rest of her life. "The organizers asked me not to speak to avoid legal problems," Gautier later told New Scientist. "But I should have refused and given my talk anyway."
Dr. Jean Kachaner, a former student of Gautier's and a pediatric cardiologist in Paris, once said that her story "starts like a fairy tale and ends like villainy." The fairy tale begins on a farm near Paris in 1925, where Marthe Gautier was born the fifth of seven children in a family that had worked the land for more than 400 years. In 1942, she followed her older sister Paulette to medical school.
Paulette was blunt about what lay ahead: "If you're a woman, and you're not the boss's daughter, you have to be twice as good to succeed." In 1944, Paulette was killed by a stray bullet during a skirmish between German troops and the French Resistance. "We knew we were not the bosses' daughters," Gautier later said, "but felt this was no reason not to try and reach the top of our profession."
She became a pediatric cardiologist -- one of only two women among 80 residents at the Hôpitaux de Paris. "I always wanted to be involved in the care of children," she said. In 1955, her mentor sent her to Harvard on a fellowship where she learned something almost no one in France knew how to do: cell culture, the technique of growing living cells outside the body.
When she returned, she took a position studying Down syndrome at the Trousseau Hospital under Professor Raymond Turpin -- a man she later described as "very distant and laconic." Turpin had long suspected Down syndrome was caused by a chromosomal abnormality, but had never pursued his own theory.
"It struck me in a rather negative way," Gautier recalled, "that here was a man who had proposed a genetic hypothesis for Down syndrome nearly 20 years before, and yet he had not gone on to pursue his theory."
No one in France knew how to culture cells to count chromosomes. Except Marthe Gautier. She raised her hand. Turpin put her on the project -- but her lab consisted of a refrigerator, a centrifuge, and a cheap microscope. She received no salary. She took out a personal loan to buy glassware.
As her grand-niece Tatiana Giraud later explained: "After the war, there was really no resources, so she had to borrow money. She paid herself for the material and everything." For the serum to keep cultured cells alive, Gautier drew blood from her own arm. She bought a young rooster to bleed periodically for its plasma.
Working alone, she developed new techniques and practiced counting chromosomes from normal cells. Again and again: 43...44...45...46. Then, in May 1958, she examined cells from a child with Down syndrome. 43...44...45...46...47. She counted again. 47. "I was alone," she told New Scientist, "but I shouted out, 'Yes!'"
It was the first time that a chromosomal abnormality had ever been linked to a human condition, but her cheap microscope couldn't identify which chromosome it was. That's when Jérôme Lejeune -- a protege of Turpin's who worked in the Down syndrome ward -- offered to take her slides to a lab with better equipment. "Naively, I consented," Gautier recalled. "I was too young to know the rules of the game." She never saw the slides again.
Seven months later, Lejeune returned with a finished paper listing three authors: his name first, Gautier's second, Turpin's last. "I was very sad and very upset when I saw the order of the names," Gautier said. "To me, it was an insult." The paper listed its most essential contributor as "Marie Gauthier" -- both her names misspelled "by a slip of the pen," she wrote, "that I dare not interpret."
"The prepared text was read to me by Dr. Lejeune at midday on Saturday, January 24, 1959, for presentation the following Monday," she recalled. "I was in shock." But French hospitals had hierarchies as rigid as the military, and Lejeune outranked her. She swallowed her protests. The paper was published.
Lejeune positioned himself as the sole discoverer of trisomy 21. President Kennedy awarded him the first Kennedy Prize. He received the William Allen Award, the highest honor in human genetics. Asked if Lejeune ever tried to correct the record, Gautier answered: "No. Never."
She recalled that a film was once made of their laboratory in which she appeared at the beginning, explaining the technology. "Two years later, I happened to see this film again. My image had disappeared, only to be replaced by that of Lejeune."
Dr. Peter Harper, a genetics historian at Cardiff University, was blunt: "Undoubtedly, Lejeune's conduct was appalling." He added that eminent geneticists in Paris generally agreed that "Marthe Gautier was the principal person, but she was sort of elbowed out of the way by Lejeune as a forceful, dynamic character." As for what Lejeune actually contributed: "What he did other than get the photographs done, it's impossible to be sure."
"I was hurt and suspected a degree of manipulation," Gautier wrote, "having a feeling of being the 'forgotten discoverer.'" She left genetics entirely and returned to pediatric cardiology at Bicêtre Hospital, where she treated children with rheumatic fever and heart defects, helped develop diagnostic procedures, and trained generations of doctors.
Because she was a woman, she was not even allowed to apply to become head of her own department. She applied for promotion to the highest research rank at INSERM for 17 consecutive years and was passed over every time. "I have no happy memories of that period," she said, "as I felt cheated in every respect."
For 50 years, she said nothing publicly. She told friends she had written an essay about what happened, but insisted it be published only after her death. Then, in 2007, the Vatican opened a cause for Lejeune's beatification -- the first step toward Catholic sainthood. In 2009, newspapers ran retrospectives about the discovery. Every story mentioned Lejeune. None mentioned Gautier. Her friend Dr. Simone Gilgenkrantz, a fellow geneticist, said the sainthood push "may have been the last straw."
At 84, Gautier broke her silence. France's National Institute of Health and Medical Research convened an ethics investigation. Their conclusion: "Marthe Gautier was a decisive person in the discovery of the extra chromosome. Simply because others on the team did not yet have the skill to do it." They added: "There is no doubt that Jérôme Lejeune promoted the discovery. But that is different from making the discovery."
The Lejeune Foundation's response was to send bailiffs to silence her at a genetics conference. Lejeune's cause for sainthood continues through the Vatican. His foundation still credits him as the sole discoverer.
Gautier was later appointed Officer of the French Legion of Honor -- a distinction she had declined twice before. When first offered at her retirement, she refused. "It was too late," she said. "I would have accepted it in 1959, but not now." The honor was meaningless decades after the credit had been stolen. She accepted the third time only "by indignation towards the impudence of the Lejeune Foundation."
Marthe Gautier died in 2022 at the age of 96. In her final years, she reflected: "Now, I finally got my due. My work is in the light."
That light will soon shine from Paris's most iconic monument. In January, the City of Paris announced that 72 women scientists will have their names engraved in gold on the Eiffel Tower -- joining the 72 men whose names have been there since 1889. Marthe Gautier is on the list. For 137 years, every name on that tower belonged to a man. Hers will be spelled correctly this time.
