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".

Rudolf Nissen, MD


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.
Dr. Rudolf Nissen (1896 - 1981).  Dr Nissen’s life is extraordinary. Born in the city of Neisse, Germany in 1896, he was the son of a local surgeon. He studied medicine in the Universities of Munich, Marburg, and Breslau. He was the pupil of the famous pathologist Albert Aschoff (discoverer of the heart’s AV node, along with Sunao Tawara).

Nissen became a professor of surgery in Berlin, and in 1933 moved to Turkey where he was placed in charge of the Department of Surgery of the University of Istanbul. In 1939 he moved to the US, first to the Massachusetts General Hospital and later to the Jewish Hospital in Brooklyn, New York. After becoming a US citizen, he moved again in 1952 to Basel, Switzerland as Chief of the Department of Surgery, where he retired in 1967. He died in 1981.

His contributions to surgery are innumerable. He wrote over 30 books and 450 journal articles. Known for the development in 1956 of what is today known as the “Nissen fundoplication” for esophageal hiatus hernia surgery, Nissen also worked with his assistant, Dr. Mario Rossetti to develop the “floppy Nissen fundoplication”, also known as the “Nissen-Rossetti procedure”. This would be enough to honor this man, still, he (with Sauerbruch) performed the first lung lobectomy and the first pneumonectomy (called then a total pneumonectomy). In 1949 he performed the first esophagectomy with a gastroesophagostomy for lower esophageal cancer.

His personal life is even more interesting. Drafted at 20, he fought in WWI and was wounded several times. In 1933, under the Nazi regime, he was ordered to fire all the Jewish-German assistants under his care. Being Jewish himself, he was told that he would keep his job, Nissen could not take this. He resigned his position and moved out of Germany.

Another little known fact is that he operated on Albert Einstein in 1948. He operated on Einstein because of intestinal cysts. Having found a developing abdominal aortic aneurysm, he reinforced it with cellophane, undoubtedly giving his patient a few extra years to live. Einstein died in 1955.

As a personal side note, our good friend Dr. Aaron Ruhalter scrubbed in with Dr. Nissen while serving as a surgical resident at the Brooklyn Jewish Hospital!
