Hélène Jégado was a domestic servant and cook from the Breton countryside who was guillotined at Rennes on February 26, 1852. The assize court of Ille-et-Vilaine had found her guilty two months earlier of poisoning three women with arsenic, of trying to poison four other people, and of 11 thefts from the houses where she worked. Investigators traced her through some 18 years of service in presbyteries and private homes, first in Morbihan and then in Rennes, and the court's own estimate, as the Archives départementales d'Ille-et-Vilaine record it, was that 37 people had been poisoned, 23 of them fatally. Most of those deaths were never tried. They had occurred more than ten years before her arrest, beyond the limit French law then set for prosecution.
The case is held in a single large trial file at the departmental archives in Rennes: interrogations, witness statements, search reports, autopsy reports and chemical analyses. In 2019 the archives built an exhibition around that file.
Jégado was born on June 17, 1803, a date her birth record gives in the revolutionary calendar as 22 Prairial an XI. The record spells her first name "Hélenne." Her parents were farmers at Kerhordevin, in the commune of Plouhinec in Morbihan. The archives describe a strongly Catholic rural world in which Breton beliefs remained alive. She spoke a mixed patois of French and Breton, spoke French poorly, and could neither read nor write.
Her mother died when she was seven, according to the curators of the 2019 exhibition. Her father placed her with two maternal aunts, Marie-Jeanne and Hélène, who were servants at the presbytery of Bubry. Domestic service was one of the better choices open to a peasant girl: the work was indoors, and servants were housed, fed and had their laundry done. She learned to cook. After four years at Bubry she followed one aunt to the presbytery of Séglien and stayed about 18 years. By the age of 30 she had worked only in presbyteries. The archives say a drinking problem eventually cost her that post.
In the late spring of 1833, at about 30, she was hired as cook at the presbytery of Guern by the priest, Joseph Le Drogo. The old presbytery is now Guern's town hall, according to the Pontivy area tourist office.
Within about four months seven people in the household died after the same illness. The archives list them as the priest's father, his mother and his niece; a day laborer; the priest himself; a second day laborer; and Jégado's own sister, Anna Jégado, who died after coming to the priest's funeral.
No one suspected her. Cholera had struck shortly before, and its signs could resemble arsenic poisoning, so the deaths were put down to disease. After the fifth death the doctor carried out an autopsy and found inflammation severe enough to explain death, but nothing that pointed to poison at the time. Many doctors, the curators note, had private doubts about such deaths and kept them to themselves. Jégado was known as pious and devoted to the sick, and she nursed each of the dying. The archives say she repeated that pattern in every house that followed.
From Guern she went back to the presbytery of Bubry, taking her dead sister's place there. The archives attribute three more deaths to her at Bubry: an aunt who worked in the house, the priest's sister and the priest's niece. The priest and his vicar became gravely ill and survived.
In 1835 she was at Locminé, cooking for the Toussaint family. The parents, a daughter named Julie and a servant died, by the archives' account. A man of the household survived; he later told the court that he had felt such revulsion toward her that he refused anything she offered him. A family member recalled that a broth she served had looked and smelled wrong. In the gossip of Locminé she was called "les foies blancs," a coward and a traitor.
In 1836 she was in service with the Hétel family at Auray. Suspicion grew there, but no one spoke of poison. Rumor, the curators write, put the deaths around her down to sorcery.
Over the next years she worked in a string of Morbihan towns. The curators' account names Guern, Bubry, Locminé, Auray, Pontivy, Hennebont, Lorient and Ploemeur, and deaths followed her from house to house, children among them. A Breton-language broadsheet poem about her life adds Pluneret and Vannes to the list.
In 1841 she was working at Ploemeur for the grandparents of a little girl, Marie Brégé, who was nearly three. The child died. She is the last of the Morbihan deaths that the archives attribute to Jégado by name.
Little is known of her life between 1841 and 1847. Between 1833 and 1841, the archives note, none of the deaths in the houses where she worked was suspected to be poisoning.
The poison in her case was arsenic trioxide, sold in the period as "mort aux rats," or rat poison. It was the substance most often used in French poisoning cases. It dissolved easily in soft foods and liquids that masked its harsh taste, and witnesses said she most often used it in broths and soups. Until 1846 it could be bought freely; after that its sale required a prescription.
Arsenic was also hard to prove, because traces of it occur naturally in the body. That began to change in 1836, when an English chemist devised what became known as the Marsh apparatus, which could measure the quantity of arsenic in tissue. The Penal Code of 1810 punished poisoning with death whether or not the victim died, because of the planning it required and what the archives call the cowardice of the method. The archives count 12 poisoners sentenced to death by the Rennes assize court, seven of them women.
Where Jégado got her arsenic is not known. Before her execution she told the prison chaplain that a woman near Guern first gave her some, and that she later bought more at Vannes and at a pharmacy in Rennes. Pharmacists' registers show no such sales.
She arrived in Rennes in August 1848, according to the archives. Her first employer there fell gravely ill, and grew worse after Jégado left, but that case was not linked to the prosecution. Early in 1849 she worked briefly for a woman who found her moody and unbearable and let her go; the woman fell ill after drinking something Jégado had prepared, and Jégado left without explanation.
In November 1849 she joined the household of the Rabot family. Their young son, Louis, was already unwell, and Jégado seemed attentive to him. He died on December 29, 1849. The family then left Rennes and dismissed her, and she complained of being turned out in midwinter. Other members of the family also fell ill.
In April 1850 she cooked for the Ozanne family. Their son Clodomir, who was five, died after an illness like the others. The archives say she showed no grief at his funeral, told the family she had nursed a similar case before, and left the next day without notice.
She next worked at an inn in Rennes. The owner found her dirty and set her to cleaning rooms. The owner fell ill and was left with lasting harm. A servant at the inn, Pérotte Macé, died quickly after an illness of the same kind. A doctor, Dr Revault-Crespin, suspected poison and asked for an autopsy, but the family refused. About a month later the owner's son caught Jégado stealing in the cellar, and she was dismissed.
In the autumn of 1850 she was hired as cook by Théophile Bidard, a lawyer and professor of law at the University of Rennes, whose house overlooked the Vilaine. She did the shopping and cooking alongside a chambermaid, Rose Tessier, whom she disliked. A shopkeeper heard her complain about taking orders from Tessier. Tessier fell ill and died. During the illness Jégado told the shopkeeper that the doctor did not understand the case and that Tessier would never recover. As in the other houses, she nursed the sick woman closely.
Bidard then hired another maid. Jégado treated her harshly and began serving her soup in a separate bowl. The young woman fell ill whenever she ate it, and Jégado asked her whether she was afraid of being poisoned. She went home to her parents, and her illness stopped.
Bidard next hired Rosalie Sarrazin. Because Sarrazin could read and write, he put her in charge of the household accounts, which annoyed Jégado. Within three weeks Sarrazin fell ill. Jégado stayed at her bedside and prepared everything she drank. Rosalie Sarrazin died on July 1, 1851.
By then two doctors who had attended the household, Dr Beaudouin and Dr Pinault, had grown suspicious, and so had Bidard. Earlier, they had asked Jégado to keep samples from the sickroom for testing, and she had not done so. They then asked Bidard to lock samples away without her knowledge. As soon as Rosalie Sarrazin died, the two doctors raised the alarm. They suspected Jégado of her death and of the two earlier deaths of maids, but they could not prove it.
The same day, July 1, 1851, the investigating judge, Hippolyte Vannier, and a police commissioner went to Bidard's house and arrested her. Vannier signed a committal order at once and notified the prison at Rennes. Before sending her there he questioned her, mostly about Rosalie Sarrazin. She admitted to "de petites discussions" with the maid, small disagreements, and said they meant nothing. She denied everything else. The archives note that the judge put his questions in a leading form, phrased as negatives that invited a yes. He told her that the truth about the deaths of Pérotte Macé, Rose Tessier and Rosalie Sarrazin would soon come out through exhumations and chemical tests.
The next day the police commissioner, Malet, searched her two attic rooms and found nothing of use. In the kitchen officers seized a medicine bottle holding the remains of a syrup that had been prescribed to Rosalie Sarrazin. None of the items seized contained poison. Rosalie Sarrazin's body was examined at the Hôtel-Dieu the day after the arrest, under police guard; Jégado was brought to attend, felt unwell and was led out.
The arrest papers recorded her name as "Jigadeau." When officials made inquiries in Morbihan, word spread that a servant named Hélène had been arrested in Rennes, and the court at Pontivy warned the procureur général, the chief prosecutor at the Rennes court of appeal, of local talk linking a servant of that name to old, unexplained deaths. Bretons, the archives write, followed each step of the case closely.
The chemical work fell to Faustino Malagutti, professor of chemistry at the faculty of sciences in Rennes. He used the Marsh apparatus to measure arsenic in the bodies of Pérotte Macé, Rose Tessier and Rosalie Sarrazin. With their families' consent, the bodies of Macé and Tessier were exhumed at 4 a.m. on August 7, 1851, at the cemetery now known as the cimetière du Nord. Jégado was present, along with witnesses who identified the bodies. The examinations were carried out on the spot. The archives describe the care taken to avoid contamination: instruments were cleaned, and the jars holding samples were sealed with paper, string and red wax.
Malagutti's report described the stains produced by his tests as "indubitablement arsenicales," undoubtedly arsenical. At the trial he showed the jury a test tube containing arsenic taken from one of the victims and explained how the apparatus worked. The case came at a time when French forensic medicine was becoming more organized, autopsy reports more detailed, and families more willing to agree to exhumations.
The archives give the court's estimate as 37 people poisoned, 23 of whom died. Most of those cases were never brought to trial. Crimes more than ten years old were beyond the reach of prosecution, so none of the deaths in Morbihan could be charged, although the facts were known and, in the curators' words, weighed against her.
She was also not charged with the deaths of Louis Rabot and Clodomir Ozanne in Rennes, although those deaths were recent enough to be tried. The archives say the court seems not to have wanted to impose exhumations on the two families, and judged the other charges sufficient.
The indictment that went to trial had 18 counts: one theft of money, ten thefts of household goods, four attempted murders and three murders, those of Pérotte Macé, Rose Tessier and Rosalie Sarrazin. She admitted nearly all of the thefts. Much of the stolen linen bore its owners' initials. "Je conviens que j'ai, en effet, volé ces deux serviettes," she said in one exchange, conceding that she had indeed stolen two napkins. Among the things found in her cupboard were a shirt, handkerchiefs and a bonnet that had belonged to Rose Tessier, and Bidard recognized a piece of sheet he had provided for Tessier's burial.
The trial began at noon on December 6, 1851, before the Cour d'assises d'Ille-et-Vilaine, sitting in the ordinary hearing room of the old Parlement de Bretagne in Rennes. Louis-Napoléon Bonaparte had seized power in Paris in a coup d'état on December 2. Her court-appointed lawyer, Magloire Dorange, asked for a postponement because several witnesses were missing, among them the deputy Baudin. Dorange told the court that Baudin had been killed in a Paris street defending the constitution against the coup. The court refused, ruling that the absent witnesses were not essential to establishing the truth.
The jury, drawn by lot, included a landowner, a wine merchant, a town councillor, a retired colonel, a tailor, a law professor and a farmer. Jégado sat on the bench unchained, between gendarmes. The Journal de Rennes reported that she came into court wrapped in a black mantelet with the hood drawn down over her face. The trial lasted eight days. Crowds gathered outside the Parlement, and police had to protect the accused from a hostile public. Le Conciliateur, a Rennes paper, wrote that many women wanted a glimpse of her. Local newspapers raised their prices while the case ran, the archives note, though national coverage was overshadowed by the coup.
The first days were given to witnesses from Morbihan. The old deaths were beyond prosecution, but the prosecution wanted the jury to hear about her character and her past. Dr Toussaint, a doctor from Locminé who had treated the victims there, his own relatives among them, gave detailed testimony. The surviving man from the Toussaint household described the revulsion that had kept him from accepting anything from her.
The Rennes witnesses followed, and the survivors were the most eagerly awaited. They described her as mean, moody, jealous and spiteful. Her former employer from early 1849 described her sudden swings of mood, cheerful one moment and changed the next. The maid who had fled the Bidard house told the court that she had forced herself to eat the soup out of fear and then began throwing it away in secret.
Jégado denied every poisoning. She had told Judge Vannier again and again that she would hold to her denial until death: "Je le soutiendrai jusqu'à la mort." She had also claimed to have tasted what she gave Rosalie Sarrazin, saying that if there had been poison in it, she would have been the first to die.
A doctor named Pitois offered the court a reading of her skull and face, in the manner of the physiognomy of the day, telling the jury she had a broad forehead and well-developed organs of hypocrisy and cunning.
Magloire Dorange came from Vieux-Vy-sur-Couesnon, a village between Rennes and Fougères, where his family owned the château d'Orange. He was an early republican who had taken part in the revolution of 1848, and he campaigned against the death penalty at a time when, the archives note, few did. Before this case he had won two trials of women: one was acquitted on a procedural flaw in a fatal arson case, the other acquitted of infanticide.
Against his client's wishes, he argued that she suffered from monomania, a fixation on a single act, in her case poisoning. The prosecution had painted her as a wicked woman who took pleasure in killing; the defense itself called her "un monstre" and "une erreur de la nature," an error of nature. Dorange called experts, but they supported the prosecution and confirmed that the killings had been planned. The chemist François-Vincent Raspail, who could not attend because he was in prison, wrote that her conduct was not that of a monomaniac, since she had prepared her acts with care.
Dorange pressed the argument anyway, hoping for imprisonment rather than death. His long closing speech became well known. He called her a "phénomène," asked the jury whether she could truly be held responsible for acts the defense accepted she had committed, said she had been born with a "malheureuse organisation cérébrale," an unhappy makeup of the brain, and asked for mitigating circumstances.
On December 14, 1851, the jury found her guilty on all 18 counts, with no mitigating circumstances. She was sentenced to death.
Dorange took the case to the Cour de cassation, arguing that one juror, who had been involved in an assault case in 1848, could not judge her fairly. The court rejected the appeal on January 16, 1852. Dorange then asked Louis-Napoléon Bonaparte, now ruling France after the coup, for a pardon. It was refused on February 22, 1852.
In prison she was ill with breast cancer. She learned of her execution the evening before, and chose "œufs à la moutarde," eggs with mustard, as her last meal. A hospital sister cared for her, and the chaplain, Abbé Tiercelin, urged her to confess.
Before witnesses, she confessed and agreed that her confession could be made public. The archives say researchers doubt that the text is authentic in its wording, because its literary style is far beyond her education. In it she denied responsibility for her sister's death and for two of the deaths at Guern, which she blamed on a day laborer. "La justice n'a pas connu tous mes forfaits," the text has her say: the courts had not known all her crimes. She asked forgiveness of God and of the victims' families. An earlier account published by Unidivers in 2019 says that during the investigation she blamed three of the Guern deaths on a woman from the area, who was later fully cleared.
She was guillotined very early on the morning of February 26, 1852, on the Champ de Mars in Rennes, now the esplanade Charles de Gaulle. The streets along the route were closed. Abbé Tiercelin stayed with her on the scaffold and recited the prayer for the dying. The next day Le Conciliateur reported that the sentence had been carried out within minutes and that the crowd dispersed in silence. A death mask taken after the execution is in the collections of the Musée de Bretagne in Rennes.
Pérotte Macé was a servant at the Rennes inn where Jégado worked in 1850. She fell ill and died quickly; a doctor's request for an autopsy was refused by her family, and her body was exhumed in August 1851. Her death was one of the three murders of which Jégado was convicted.
Rose Tessier was the chambermaid in Théophile Bidard's household, where Jégado was the cook from the autumn of 1850. Jégado resented taking direction from her. She died after an illness during which Jégado nursed her and told a shopkeeper she would never recover. Her death was the second of the three convictions.
Rosalie Sarrazin joined the Bidard household after Tessier's death. She could read and write, and Bidard trusted her with the household accounts. She died on July 1, 1851, three weeks after falling ill, and her death led directly to Jégado's arrest. It was the third conviction.
Louis Rabot, a young boy in a Rennes family, died on December 29, 1849, and Clodomir Ozanne, who was five, died in April 1850. Neither death was tried.
Of the Morbihan victims, the archives name the priest Joseph Le Drogo of Guern, whose parents and niece died in the same household in 1833; Anna Jégado, Hélène's sister, who died after coming to the priest's funeral; members of the Toussaint family at Locminé in 1835, among them a daughter, Julie; and Marie Brégé, not yet three, who died at Ploemeur in 1841 while Jégado worked for her grandparents. Others are known only by their place in a household: day laborers, servants, an aunt, a priest's sister and niece.
Only three deaths were ever proved in court. Every other death linked to Jégado rests on the investigation of 1851, on testimony that could not lead to charges, and on later accounts, and the figures differ.
The Archives départementales d'Ille-et-Vilaine give the court's estimate as 37 people poisoned, 23 of whom died. A French execution ballad printed in 1852, held in the University of Melbourne's French Execution Ballads database, was titled as the story of a poisoner "accused of having attempted the lives of 37 people, of whom 25 died." A bibliography of French judicial history at Criminocorpus records an 1863 two-page pamphlet printed at Joinville under a similar title, which the record gives as 57 people, 25 of whom died. A Breton-language broadsheet poem catalogued on Kan.bzh says she poisoned 37 people over 19 years and that nine survived. A 2019 Unidivers article put the possible total as high as 60, while noting that the figure was a claim; the Pontivy area tourist office also cites "about sixty" from some sources.
Jégado herself never accepted the poisoning charges in court. The confession taken by Abbé Tiercelin on the eve of her execution, if it is genuine, admitted crimes in general terms while denying three of the deaths at Guern, and the archives record historians' doubts about its wording.
Her motive was not established at the trial. Writers have offered explanations, from her drinking and her temper, recorded by witnesses, to her childhood fears of the Ankou, the figure of death in Breton belief. The archives treat the Ankou idea as something some people believe that cannot be proven.
The case passed quickly into popular print. Ballads, or complaintes, were sold about her life and death; the departmental archives hold one from 1851, and the Melbourne database records an 1852 ballad sung to the tune of "Fualdès." A Breton-language poem, "Buhez Helen Jégadeu," attributed to P.-M. Jaferédo, went through the households where she had worked, from Guern and Bubry to Ploemeur, Locminé, Auray, Pluneret, Vannes and Rennes. In 1967 the case was the subject of an episode of the programme "En votre âme et conscience," which dramatized historic French trials.
The novelist Jean Teulé told her story in the 2013 novel "Fleur de tonnerre," adapted for the screen in 2017 by the director Stéphanie Pillonca-Kervern. Olivier Keraval and Luc Monnerais drew on the trial file for a two-volume comic, "Arsenic," published in 2017 and 2018; Keraval said that the childhood scenes were invented and that the rest followed the historical record.
From September 10, 2019, to January 2020, the Archives départementales d'Ille-et-Vilaine mounted an exhibition, "Hélène Jégado: un bol d'arsenic?", showing the trial file, autopsy reports, her prison register and a report from Le Conciliateur alongside pages from the comic. Philippe Bohuon, a member of the archives' heritage staff, told Unidivers that hard living conditions, high mortality and cholera had allowed her killings to pass unnoticed for years.
On October 4, 2019, the Rennes court of appeal staged a reenactment of her trial as part of its "Nuits bretonnes du droit," with working judges and court officials in the roles. Twelve jurors were drawn by lot from the audience; a court official made the prosecution's demand for the death penalty, and a judge, Andrée Georgeault, played Jégado, austere and nearly silent throughout. The court called her the greatest poisoner in France.
In 2024 the historian Justine Jouet published "La Jégado, dans les pas d'une empoisonneuse en Bretagne" with Coop Breizh. Unidivers reported that she worked from the case file assembled by Judge Vannier, some 400 documents that the departmental archives had digitized.
