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".

False Vesalius postage stamps discovered


There are many in the world that are fascinated by the life and works of Andreas Vesalius (1514 -1564). This has created a market for “Vesaliana”. These are books, art, medals, and works are related to Vesalius. As an example, an original 1543 Fabrica sells today for 400 thousand dollars! Even the “New Fabrica” by Drs. Garrison and Hast has cuadrupled its value in only two years since its publication!

Some of the most coveted items are stamps that celebrate the illustrious anatomist. Probably the most detailed research on the topic was made by Prof. Omer Steeno and Dr. Maurits Biersbrouck, both contributors to this website. Their research is constantly updated and the latest iteration of their work is “Andreas Vesalius in Philately” published in WordPress.com.

In a recent private communication Prof. Steeno regretted that unscrupulous individuals have taken to forge and falsify stamps. A clear case of this is the stamp collection “Les Grands Scientifiques de la Rennaissance” published in November 23, 2006 by the Republic of Djibouti. The stamps (shown in the accompanying image) depict Leonardo da Vinci, Nicolas Copernicus, Galileo Galilei, and Andreas Vesalius.  As a Vesaliana collector, who would not want this set of stamps placing Vesalius in such company?

Djibouti is an African country that gained its independence from France in 2007 and is located in the horn of East Africa and the opening of the Red Sea into the Gulf of Aden.

Drs. Steeno and Beisbrocuk contacted the Djibouti postal service and were able to confirm in February, 2016 that indeed these stamps are false and collectors should be aware.
