Pierre-François Percy

Pierre-François Percy (28 October 1754 – 18 February 1825) was a French medical doctor and surgeon.

He was surgeon-in-chief of Napoleon's Grande Armée during the Napoleonic campaigns in Germany and Poland, and present at the Battles of Jena and Friedland.

Percy was doctor to the polyphage Tarrare during Tarrare's time in the French Army and later, in 1798 at the time of his death. In 1804, he wrote , a paper on the life and medical history of Tarrare.

During the wars of the French Revolution and Empire, he invented a new kind of ambulance usable on the battlefield known as a "wurst", as well as the cork-balls and the surgical quiver.

He served on the main battlefields of the Empire and became chief surgeon of the , but had to leave the army after 1809 because of ocular problems. His replacement as chief surgeon of the Grande Armée was Nicolas Heurteloup (1750-1812).

He resumed service in 1814 and his conduct earned him the esteem of the Allied armies.

Percy had to retire during the Restoration and died in Paris on 18 February 1825.

Percy was a member of the Academy of Sciences, Academy of Medicine, Commander of the Legion of Honor and Baron of the Empire.

Works Percy is perhaps best-known for his Journal des Campagnes, which was published in 1904 by the Franc-comtois historian Émile Longin, and translated in 2024 into English by the author Calum Johnson. The Journal is a frequent, almost-daily account of Percy's life on campaign in the Revolutionary and Napoleonic Wars. Some manuscripts were lost in the 79 years between the surgeon's death and the publication of the Journal, although Percy's writings on the 1806 and 1807 campaigns in Germany and Poland are almost complete. The Journal also includes notes from the 1799 and 1800 campaigns in Helvetia and Germany, the 1805 Austerlitz campaign, and the campaign in Spain (1808-1809).

Percy's Journal describes the often-terrible conditions of army life and military surgery, and the chaos that ensued in the aftermath of major battles.

His account describes meetings with Jourdan, Napoleon and, at Tilsit in 1807, the monarchs Alexander I of Russia and Frederick William III of Prussia.
