Auenbrugger invented percussion — the art of striking a surface part of the body with short, sharp taps to diagnose the condition of the parts beneath the sound — as a diagnostic technique. On the strength of this discovery, he is considered one of the founders of modern medicine. His father, a wealthy hotel keeper, who died when Leopold was quite young. Nevertheless, he gave his son every opportunity for an excellent preliminary education in his native town and then sent him to Vienna to complete his studies at the university of Vienna, where one of his teachers was Gerhard van Swieten, who, through a series of reforms had made the medical faculty one of the leading in Europe.
Auenbrugger was graduated as a physician at the age of 22 and then entered the Spanish Military Hospital of Vienna, where he worked as assistant physician from to , but did not receive a salary until Because of his work in the hospital, Empress Maria Theresia in ordered the Faculty of Medicine to admit him as a member without charging him any fees. From to he was chief physician at the Spanish Hospital, obtaining experience in diagnosis of chest diseases.
Percussive Diagnosis During this time, he found out that, by applying his ear to the patient and tapping lightly on the chest, one could assess the texture of underlying tissues and organs.
At that time, pulse and respiration were the principal tools of examination, of patients suffering from diseases of chest. With his new method, he was able to plot outlines of the heart. It was the first time that a physician could relatively accurately and objectively determine an important sign of diseases. He published his findings in a booklet, but nobody paid much attention to it. The Diagnostic Value of Percussion During his ten years of patient study, Auenbrugger confirmed his observations on the diagnostic value of percussion by comparison with post-mortem specimens, and besides made a number of experimental researches on dead bodies.
He injected fluid into the pleural cavity, and showed that it was perfectly possible by percussion to tell exactly the limits of the fluid present, and thus to decide when and where efforts should be made for its removal. Studies in Tuberculosis His later studies were devoted to tuberculosis.
He pointed out how to detect cavities of the lungs, and how their location and size might be determined by percussion. He also recognized that information with regard to the contents of cavities in the lungs and conditions of lung tissue might be obtained by placing the hand on the chest and noting the vibration, or fremitus, produced by the voice and breath. Among other things, he described the phenomenon of damping and explained it with the reduced air content of the tissue.
He also listed various clinical pictures in which he found an increased damping of the knocking sound. It is considered a book that marks an epoch in the modern history of medicine. Only another of his writings on the treatment of various diseases with Camphor brought him far greater prestige. In he was awarded the noble title Noble of Auenbrugg. It was not until a French translation by Jean-Nicolas Corvisart des Marest, personal physician to Napoleon, appeared in that the diagnostic method gained worldwide acceptance.
Auenbrugger lived to the happy old age of He is sometimes said to have died in the typhus epidemic of , but the burial register of the parish church in Vienna, of which he had been for half a century a faithful member, shows that he did not die until William Ayliffe also refers to the history of stethoscope diagnosis.
