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".

Interesting discovery in an Ex-Libris

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.

Osler MedChi Ex-Libris

For centuries, book owners and collectors have used bookplates to identify their books and their collections, a tradition that seems to be falling in disuse. Not me, I have one that you can see here.

Bookplates (also known as Ex-Libris) can be a tantalizing study, and finding an interesting one is part of what makes an old book a journey of discovery. Every detail in an old book is important. Who owned it? What is their story? Did they leave personal notes within the pages of the books? I have found prescriptions, personal notes, medical shopping lists, and in some cases corrections to the book itself! One of the most interesting cases of this is Vesalius' Annotated Fabrica!

Bookplates are very personal. In many cases, they depict the coat of arms of the owner’s family, sometimes a motto that drove the book’s owner, the book owner's hobbies, and in some cases a humorous jab at something.

While researching my series of articles on Dr. Ephraim McDowell, I ordered the book “EPHRAIM MCDOWELL, FATHER OF OVARIOTOMY AND FOUNDER OF ABDOMINAL SURGERY. With an Appendix on JANE TODD CRAWFORD”. By AUGUST SCHACHNER, M.D. Cloth, 8vo.A p. 33I. Philadelphia, J. B. Lippincott CO., I921. A great book, I finished reading it overnight!. Dr. McDowell has also been featured in this blog in the series "A Moment in History"

What interested me was the bookplate on the book frontis, a picture of which I placed in this article. It is from the Library of the Medical and Chirurgical faculty of the State of Maryland, and has a legend that states "Purchased through the William Osler Testimonial fund for the advancement of Medicine”. It depicts a physician (probably Hippocrates) taking the pulse of a patient.

Further research indicated that this bookplate was created to honor Sir William Osler by the Maryland State Medical Society and that Dr. Osler’s books never had personal bookplates. MedChi (Maryland State Medical Society) commissioned this plate that depicts the four seals of the universities with which Osler was affiliated: McGill in Montreal, University of Pennsylvania in Philadelphia, Johns Hopkins in Baltimore and Oxford in England. The images are flanked by two rods of Asclepius.This Ex-Libris was designed and drawn by Max Brödel (1870 – 1941) a famous medical illustrator who worked at the Johns Hopkins School of Medicine in Baltimore and illustrated for Harvey Cushing, William Halsted, Howard Kelly, and other notable clinicians. Brödel was a personal friend of Osler. The bookplate was such a hit that doctors from all over the country requested copies of it, which the librarian at the time Ms. Marcia Crocker Noyes,  sent but with the request of receiving the requestor’s own bookplate. You can see all of them in the attached links in the "Sources" section. Interestingly, Ms. Marcia Crocker Noyes has been suspected of still haunting the library where she worked!!

An old book is important not only because of its content, but also because of its provenance. You know where you are going to start reading it, but you never know where are you going to end in researching it. Should you want to have your own bookplate, you can order them from BookPlateInk. On a personal note, develop your own bookplate. It's your legacy. If you want to see my Ex-Libris, it is in my library catalog page. Dr. Miranda.
