René Laennec was a French physician who invented the stethoscope. Known as the father of clinical auscultation, René Laennec is considered to be one of the greatest doctors of all times. Born as the son of a lawyer, he was actually discouraged from practicing medicine as a young man. But as fate would have it, he proceeded to study under several famous physicians, including Dupuytren and Jean-Nicolas Corvisart-Desmarets before becoming a prominent physician in his own right. The introduction of auscultation—a new method to diagnose diseases was his biggest contribution to medical science. This method involves listening to and identifying various sounds made by different body organs. Before the invention of this method, Laennec’s diagnostic method involved placing his ear on the chest of his patients. This method made him quite uncomfortable especially while he was diagnosing young women and hence this led to the innovation of a new device called stethoscope which he initially termed as “chest examiner”. With his new chest examiner, he was able to study the different sounds of the heart thus categorizing them as either healthy or unhealthy. Though criticized initially, his works were way ahead of his times and had a great impact on medical science.

A brilliant student, he became a member of the Societe d'Instruction Medicale.

  • In 1816, René Laennec was appointed a physician at the Necker Hospital in Paris. During that period, doctors used to place their ear on the chest of the patient to listen to chest sounds. Laennec found this method embarrassing when treating women, especially overweight ones.

  • When a young overweight woman came to him complaining of chest problems, he found the traditional method of listening to heartbeats to be very ineffective. So he rolled some paper into a cylinder and placed one side on the woman’s chest and the other to his ear. He could now hear the sounds more clearly.

Major Works
  • René Laennec invented the stethoscope. The initial model he developed consisted of a wooden tube and was monaural; it was very similar to the common ear trumpet, a historical form of hearing aid. The new device helped him in classifying the terms rales, rhonchi, crepitance, and egophony pertaining to sounds captured by the stethoscope.

  • He coined the term melanoma, referring to a type of cancer that typically occurs in the skin but may rarely occur in the mouth, intestines, or eye. He was the first to recognize that melanotic lesions were the result of metastatic melanoma. His report on the disease was initially presented during a lecture for the Faculté de Médecine de Paris in 1804 and then published as a bulletin in 1806.
