Ambroise Paré

Lore & Background

Paré reintroduced the ligature of arteries instead of cauterization during amputation, designing the "Bec de Corbeau" ("crow's beak") as a predecessor to modern haemostats. He detailed this technique in his 1564 book *Treatise on Surgery*. During the Piémont campaign of 1537–1538, he compared soldiers treated with boiling elder oil and cauterization against those treated with a mixture of egg yolk, oil of roses, and turpentine, finding the latter far more effective due to turpentine's antiseptic properties—he published this in his first book in 1545. He documented phantom limb pain in amputees, attributing it to the brain, not remnants of the limb. In 1542, during the siege of Perpignan, he helped extract a bullet from Maréchal de Brissac by asking him to assume the exact position he was in when shot. Paré revived podalic version in obstetrics, showing how surgeons could safely deliver infants instead of dismembering them. He also introduced lancing infants' gums during teething, a practice that persisted until the late nineteenth century. In 1552, he was accepted into royal service under Henry II, though he could not cure the king's fatal head wound from a tournament in 1559. According to Henri IV's chief minister Sully, Paré was a Huguenot, and on 24 August 1572, the day of the St. Bartholomew's Day Massacre, King Charles IX saved his life by locking him in a clothes closet. He died in Paris on 20 December 1590 from natural causes in his 80th year, and is buried at the church of Saint André-des-Arts.

Reader's Guide

Ambroise Paré's significance lies in his transformation of surgery through direct observation and evidence. His battlefield comparison of boiling oil versus a turpentine-based ointment for gunshot wounds exemplified an early application of the scientific method. By reintroducing the ligature of arteries and designing the 'crow's beak' clamp, he offered an alternative to cauterization that reduced shock and death from hemorrhage, despite infection risks. His work in obstetrics, reviving podalic version, saved many infants from dismemberment during difficult births. Paré also laid foundations for modern forensic pathology through his methodical studies of violent death on internal organs and his creation of legal medical reports in *Reports in Court*. His 1567 bezoar stone experiment—where a poisoned cook died after taking a bezoar—demonstrated a willingness to challenge popular beliefs with empirical evidence. Though a Huguenot, he navigated religious dangers to serve four French kings. His collected works, first published in Paris in 1575 and frequently reprinted in German, Dutch, and English (Thomas Johnson's 1634 translation), spread his innovations across Europe.

Did You Know?

• Paré's personal motto, 'Je le pansai, Dieu le guérit' ('I bandaged him and God healed him'), is inscribed on his statue in Laval.
• In 1567, Paré proved bezoar stones could not cure all poisons by having a condemned cook take one after being poisoned—the cook died in agony seven hours later.
• Paré designed the 'Bec de Corbeau' ('crow's beak'), a predecessor to modern haemostats, for ligating arteries during amputation.
• On the day of the St. Bartholomew's Day Massacre (24 August 1572), King Charles IX saved Paré's life by locking him in a clothes closet.
• Paré documented phantom limb pain in amputees and attributed the sensation to the brain, not remnants of the limb.

From Laval to the Royal Court

Paré was born in 1510 in Bourg-Hersent, later incorporated into Laval, then part of the province of Maine in northwestern France. As a child he watched and was first apprenticed to his older brother, a barber-surgeon in Paris. He was also a pupil at Hôtel-Dieu, France's oldest hospital. In 1552, Paré was accepted into royal service of the Valois Dynasty under Henry II; he stayed in the service of the kings of France to the end of his life in 1590, ultimately serving Henry II, Francis II, Charles IX, and Henry III. He was also a member of the Parisian barber surgeon guild. Despite his proximity to power, he could not cure Henry II's fatal blow to the head received during a tournament in 1559.

Rewriting the Rules of Surgery

Paré's most celebrated contributions emerged from the battlefield, where he refused to let inherited dogma override what he observed. During the Piémont campaign of 1537–1538, he treated one group of wounded soldiers with the traditional boiling elder oil and cauterization, and another with a preparation of egg yolk, oil of roses, and turpentine, leaving them overnight. The next morning he compared the two groups and found that those who had received the gentle ointment had recovered, while those subjected to the boiling oil were in agony. The antiseptic quality of turpentine explained the difference, and Paré avoided cauterization thereafter, publishing his findings in his first book *The method of curing wounds caused by arquebus and firearms* in 1545. He also reintroduced the ligature of arteries instead of cauterization during amputation, designing the 'Bec de Corbeau' ('crow's beak'), a predecessor to modern haemostats. He detailed this technique in his 1564 book *Treatise on Surgery*. He documented phantom limb pain in amputees, attributing it to the brain, not remnants of the limb. In 1542, during the siege of Perpignan, he helped extract a bullet from Maréchal de Brissac by asking him to assume the exact position he was in when shot.

Beyond the Operating Table

Paré's medical curiosity extended beyond the battlefield. In obstetrics, he revived the practice of podalic version, showing how even in cases of head presentation, surgeons could often deliver the infant safely instead of having to dismember the infant and extract it piece by piece. During his time at Hôtel-Dieu, Paré directly influenced the education of future royal midwife Louise Boursier. His pupil Jacques Guillemeau translated his work into Latin and later wrote his own treatise on midwifery, published in English in 1612 as *Childbirth; or, The Happy Delivery of Women*. Paré also introduced the lancing of infants' gums using a lancet during teething, believing that teeth were failing to emerge due to lack of a pathway and that this failure was a cause of death—this practice persisted until the late nineteenth century. In 1567, he described an experiment to test the properties of bezoar stones. A cook condemned to hang for stealing silver cutlery agreed to be poisoned instead, on the condition that he would be given a bezoar and go free if he survived. The stone did not cure him, and he died in agony seven hours after being poisoned, proving that bezoars could not cure all poisons.

Faith, Peril, and a Lasting Legacy

Paré's personal philosophy of medicine was captured in a simple line he wrote after treating Captain Rat during the Piémont campaign: 'Je le pansai, Dieu le guérit' ('I bandaged him and God healed him'). These words, inscribed on his statue in Laval, are reminiscent of the Latin adage 'medicus curat, natura sanat' ('The physician cures, nature heals'). According to Henri IV's chief minister Sully, Paré was a Huguenot, and on 24 August 1572, the day of the St. Bartholomew's Day Massacre, King Charles IX saved his life by locking him in a clothes closet. Yet Paré kept up the appearance of being Catholic to avoid danger: he was twice married, had his children baptized, and was buried according to the Catholic faith at the church of Saint André-des-Arts. He died in Paris on 20 December 1590 from natural causes in his 80th year. A collection of his works, published separately throughout his life, was assembled in Paris in 1575 and frequently reprinted in German, Dutch, and English, the latter through Thomas Johnson's 1634 translation.
