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".

The Ephraim McDowell House and Museum (4)

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.

This is the continuation of the article “The Ephraim McDowell House and Museum (3)”. For the first article, click here.

The rest of the house is interesting. The kitchen is an open hearth typical of the times and beneath the operating room. Candle molds, butter churners, baking tables, iron cooking utensils, etc. The guide explained that most of the cooking work was done by slaves.

To the back of the house if a large garden. Part of it is shaped as a Maltese cross, and this is where Dr. McDowell cultivated medicinal plants and herbs for his practice and the apothecary, The garden has several monuments, one of which is the original slab that covered Dr. McDowell's tomb.

The apothecary

This "pharmacy" of the times is incredibly well-preserved, maintained and furnished. It is said that Dr. McDowell worked so much at this place that he eventually moved to the country to a second house he named "Cambiskenneth" after a famous local native american chief.

The apothecary has a basement that is off-limits to visitors, but there are photographs of the location for visitors to see.

Some of the porcelain and glass containers still have some of their contents.

Additional historic buildings

Just across from the McDowell House and Museum is the Constitution Square, a site that I would encourage you to visit. Following is an excerpt of the Danville KY website on the Constitution Square Historic Site:

"This is the birthplace of Kentucky's statehood. In 1776, Kentucky was still part of the frontier and a county of Virginia. The Wilderness Road, blazed by Daniel Boone, led pioneers through the Cumberland Gap and into Central Kentucky. Danville's prominent location on the Wilderness Road caused it to become a crossroad for early settlers, and a center of political activity.

By 1785, Danville was chosen as Kentucky's first seat of government, and a meetinghouse, courthouse and jail were built to administer the growing territory. Still bound to Virginia laws, though, several Danville citizens formed the political club that recognized the need for a convention to discuss statehood. Between 1784-1792, ten constitutional conventions took place at the courthouse of Constitution Square. In 1790, Kentucky delegates accepted Virginia's terms for separation from the state. On June 1, 1792, Kentucky became the fifteenth state in the union, and Isaac Shelby, a Revolutionary War hero, was named the first Governor of the Commonwealth."

Several original buildings and replicas are found at this site.

In closing this series of articles I can only say that this was an interesting personal and learning experience. Being able to visit The Ephraim McDowell House and Museum allowed me to envision the life of this time. To place it in perspective the year that Dr. McDowell operated on Mrs. Crawford was 1809. On the same year Abraham Lincoln was born  (only 35 miles from the farm of Mrs. Crawford), James Madison was the 4th president of the United States of America (which had only 15 states and 6 territories), Napoleon occupied Vienna, and Ludwig van Beethoven had just finished writing his Fifth Symphony.

Following is a large image of the original house prior to its renovation. The image is in the public domain from a biographical book by Dr. McDowell's granddaughter Mary Young Ridenbaugh.
