A Moment in History

Jean-Louis Petit

Jean Louis Petit
(1674 – 1750)

French surgeon and anatomist, Jean Louis Petit was born in Paris in on March 13, 1674.  His family rented an apartment at his house to Alexis Littre (1658 – 1726), a French anatomist. Petit became an apprentice of Littre at seven years of age, helping him in the dissections for his lectures and at an early age became the assistant in charge of the anatomic amphitheater.

Because of Petit’s dedication to anatomy and medicine, in 1690 at the age of sixteen, became a disciple of a famous Paris surgeon, Castel.

In 1692, Petit entered the French army and performed surgery in two military campaigns. By 1693 he started delivering lectures and was accepted as a great surgeon, being invited to the most difficult operations.  In 1700 he was appointed Chief Surgeon of the Military School in Paris and in the same year he received the degree of Master of Surgery from the Faculty of Paris.

In 1715 he was made a member of the Royal Academy of Sciences and an honorary member of the Royal Society of London. He was appointed by the King as the first Director General of the Royal Academy of Surgery when it was founded in 1731.

Petit’s written works are of historical importance.  “Traite des Maladies des Os” ( A Treatise on Bone Diseases);  “Traite des Maladies Chirurgicales et des Operation” (A Treatise on Surgical Diseases and their Operations” This last book was published posthumously in 1774. He also published a monograph on hemorrhage, another on lachrymal fistula, and others.

He was one of the first to perform choIecystotomy and mastoidotomy. His original tourniquet design for amputations saved many in the battlefield and the design of the same surgical instrument today has not changed much since its invention by him.

His name is remembered in the lumbar triangle, also called the "triangle of Petit", and the abdominal hernia that can ensue through that area of weakness, the lumbar hernia or "Petit's hernia".

Don Antonio de Gimbernat y Arbós


This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.To search all the articles in this series, click here.

UPDATED: Don Antonio de Gimbernat y Arbós (1734-1816). Spanish anatomist and surgeon. His complete name was Don Manuel Luis Antonio de Gimbernat y Arbós. He was born to a farmer’s family in 1734 in Cambrils (Tarragona), in what today is Cataluña. Gimbernat studied Latin and Philosophy at the University of Cervera, continuing his studies at the School of Surgery in Cádiz, where he graduated in 1762.

Gimbernat joined the Spanish Navy, but because of this capabilities, in 1765 he was offered the position of Anatomy Professor at the Royal School of Surgery in Barcelona. In 1768 he made an anatomical discovery that would render him immortal: he demonstrated the presence of the lacunar ligament. Furthermore he applied his knowledge of this ligament to improve on the surgical technique to reduce a strangulated femoral hernia. Gimbernat also discovered the lymph node found deep in the femoral ring (later to be known as Cloquet’s or Rosenmueller’s node)

In 1774 Gimbernat traveled through Europe to learn the latest surgical techniques. This trip was sponsored by King Carlos III. During his stay in London Gimbernat studied with John Hunter (1728 – 1793). In an attitude not common for a student at the time, at the end of one of Hunter's anatomical lectures on hernia, Gimbernat asked to go to the cadaver and demonstrate his findings. With approval of the teacher, he demonstrated for Hunter the lacunar ligament as well as his strangulated femoral hernia technique. Hunter watched the demonstration and at the end of it he just said "You are correct, sir".

Hunter was so impressed that from that day on he referred to the lacunar ligament as “Gimbernat’s ligament" and adopted his surgical technique. Gimbernat also showed Hunter his studies and technique to repair diaphragmatic hernias.

Manuel Gimbernat participated in the creation of the Spanish Royal School of Surgery, became a professor of surgery and  orthopedics, and in 1789 he was named First Royal Surgeon and president of all the surgical schools in Spain.

In 1793, Gimbernat published his “ Nuevo Método de Operar en la Hernia Crural” dedicated to King Charles IV,  which was translated as “A New Method of Operating for the Femoral Hernia”, into English in 1795.

In 1803 the Spanish king Carlos IV commissioned Don Francisco Javier de Balmis i Berenguer (1753 – 1819), a Spanish physician, to find a solution to the smallpox problem in the Spanish colonies in South America. While planning what was later to be known as the “Royal Philanthropic Vaccine Expedition” Balmis received critical contributions from Don Manuel Gimbernat.

All of his titles and positions were removed by King Fernando VII because Gimbernat was a supporter of Napoleon during his invasion of Spain in 1808.  Sick, poor, blind, and with ailing mental faculties, Don Manuel Gimbernat died in Madrid on November 17, 1816.

Gimbernat was also a pioneer in ophthalmology, vascular surgery and urology. As for his incredible anatomical dissection capabilities, Gimbernat often said “mi autor más favorito es el cadaver humano" (my favorite author is the human body”

Personal note: My thanks to Dr. José Luis Bueno-López for his correction of the name of Gimbernat: "Although don Antonio de Gimbernat y Arbós was born in a town in Catalonia, Spain, he never wrote his name nor his contemporaries did, with the particle 'i' between his two family names (in the manner of the Catalan language) but with particle 'y' in the way of the Spanish language". There are many articles where Gimbernat's last name is written "Gimbernat i Arbos" (see link #3 on the Source section) which according to Dr. Bueno-López is incorrect.
