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".

Otto C. Brantigan, 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.

Otto C. Brantigan, MD. (1904-1981) An American surgeon and anatomist, Otto Charles Brantigan  was born in Chattanooga, TN in 1904. Having dropped out of high school to help his family and working as a first class machinist, he decided to continue with graduate school. He studied at the Northwestern University in Chicago, where he graduated from the Medical School in 1933.  In 1948 he became Chief of Surgery, and eventually became Professor of Surgery, Professor of Thoracic Surgery, and Professor of Anatomy at the Maryland School of Medicine.  He retired in 1976 having earned many accolades for his profuse surgical work and publications.

As a surgeon of the times, Dr. Brantigan had a wide area of interest. His over 110 publications and surgical work range from thoracoscopy to vascular, plastic, cardiac, and orthopedic surgery. He is most remembered for the pioneer work he did on chronic obstructive pulmonary disease (COPD), emphysema and lung volume reduction surgery (LVRS), which he presented in 1958. The procedure had (at the time) a very high mortality rate  (16 -20%) and Brantigan's work was not readily accepted.

It was not until J. Cooper and his team, revisited the operation proposed by Brantigan  that the operation was accepted, now with new surgical stapling and staple line buttressing technology.  Dr. Brantigan's name was recognized as a pioneer in lung emphysema surgery, unfortunately 14 years after his death. In 1994 his son, Dr Charles O. Brantigan delivered a beautiful biography of Dr. Otto Brantigan in the same meeting where Cooper presented his results with LVRS.

Personal note: I am proud to own one of the copies of Dr. O.C. Brantigan;s "Clinical Anatomy", a book that I use quite frequently. It is listed in my library catalog. Dr. Miranda.
