Pierre Adolphe Piorry
Pierre Adolphe Piorry (31 December 1794 – 29 May 1879) was a French physician born in Poitiers. He invented pleximetry (a method for the investigation of internal organs using percussion) and was the creator of medical terms toxin, toxemia and septicemia.
He studied medicine in Paris, where his instructors included Jean-Nicolas Corvisart (1755–1821), Gaspard Laurent Bayle (1774–1816), François Broussais (1772–1838), and François Magendie (1783–1855). While still a student he was part of the Napoleonic Wars in Spain. In 1816 he earned his doctorate with a thesis titled Du danger de la lecture des livres de médecine par les gens du monde (On the danger of reading medical text books by the laity).
René Laennec's invention of the stethoscope (1816) and his publication of De l' Auscultation Médiate (1819) inspired Piorry to make an analogous contribution to the science of medical percussion. In 1826 Piorry introduced the pleximeter (le plessimétre), a device used to help delineate internal organs, of which he described in his 1828 treatise De la Percussion Médiate.
