Introduction and background

The stethoscope is the image of medicine. It is a visible sign of the years of education a doctor went through to receive their title and their ability to practice.

Abstract

Rene Theophile Hyacinthe Laënnec (1781–1826) was a French physician who, in 1816, invented the stethoscope. Using this new instrument, he investigated the sounds made by the heart and lungs and determined that his diagnoses were supported by the observations made during autopsies. Laënnec later published the first seminal work on the use of listening to body sounds, De L’auscultation Mediate (On Mediate Auscultation). Laënnec is considered the father of clinical auscultation and wrote the first descriptions of bronchiectasis and cirrhosis and also classified pulmonary conditions such as pneumonia, bronchiectasis, pleurisy, emphysema, pneumothorax, phthisis and other lung diseases from the sounds he heard with his invention. Laënnec perfected the art of physical examination of the chest and introduced many clinical terms still used today.

René Laennec

French physician (1781–1826)

René-Théophile-Hyacinthe Laennec^[a] (French:[laɛnɛk]; 17 February 1781 – 13 August 1826) was a French physician and musician. His skill at carving his own wooden flutes led him to invent the stethoscope in 1816, while working at the Hôpital Necker.^[1] He pioneered its use in diagnosing various chest conditions. He became a lecturer at the Collège de France in 1822 and professor of medicine in 1823. His final appointments were that of head of the medical clinic at the Hôpital de la Charité and professor at the Collège de France. He went into a coma and subsequently died of tuberculosis on August 13, 1826, at age 45.^[2]

Early life

Laennec was born in Quimper (Brittany). His mother died of tuberculosis when he was five years old, and he went to live with his great-uncle the Abbé Laennec (a priest).^[3] As a child, Laennec became ill with lassitude and repeated instances of pyrexia. Laennec was also thought to have asthma.^[4] At the age of twelve, he procee
