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.
René Laennec started publishing important scientific papers on a variety of topics in 1802. One of his major papers was on peritonitis (inflammation of the abdominal cavity's lining).
He suffered from poor health and shortness of breath but his health problems did not deter his commitment to medical science. He continued working hard in spite of his health issues.
In 1804, his doctoral thesis on the relationship of the ancient Greek Hippocratic doctrine to practical medicine was accepted and he was elected to the Societe de l'Ecole de Medecine, formerly the Royal Society of Medicine.
Soon he became an editor and contributor to the esteemed ‘Journal of Medicine, Surgery, and Pharmacy’ and proceeded to open his own private practice. During the Napoleonic Wars in 1812-13, he took charge of the wards in the Salpêtrière Hospital in Paris, which was reserved for wounded soldiers.
A stanch Roman Catholic, his religious affiliation helped him to secure an appointment as personal physician to Joseph Cardinal Fesch, half brother of Napoleon and French ambassador to the Vatican in Rome. He remained Fesch’s physician until 1814.
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.
He improvised on the new device he had just designed and called it a stethoscope, from stethos (chest), and skopos (examination). He published ‘De l’auscultation médiate’ (“On Mediate Auscultation”) in 1819; it was the first discourse on a variety of heart and lung sounds heard through the stethoscope.
After the publication of the English translation of this seminal work, he gained much popularity worldwide. Physicians from all over Europe came to him to learn about the new device and he became a lecturer of international repute.
He was appointed chair and professor of medicine at the College of France in 1822. The next year, he became a full member of the Academy of Medicine.
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.
His works helped in understanding the liver disease, cirrhosis. He coined the term cirrhosis, using the Greek word (kirrhos, tawny) that referred to the tawny, yellow nodules characteristic of the disease. Laennec's cirrhosis, a disease associated with inflammatory polyarthritis is named after him.
René Laennec was born on 17 February 1781, in Quimper, France, to Théophile-Marie Laënnec and Michelle Félicité Guesdon Laënnec. His mother died of tuberculosis when he was five or six years old, leaving Rene and his brother in the care of their father.
Their father, a lawyer, was an incompetent guardian, known for his reckless spending. In 1793, during the French Revolution, the boys were sent to live with their uncle Guillaime-François Laennec who was the dean of medicine at the University of Nantes.
Under his uncle’s able guidance the young René too developed an interest in medicine and began his medical studies. His father, however, did not want his son to become a doctor and tried to dissuade him from practicing medicine.
Confused, Laennec spent a period of time studying Greek and writing poetry. But he could not stay away from the medical field for long. He soon enrolled as a medical student in Paris’ finest hospital, the Charite, and studied under prominent physicians like Dupuytren and Jean-Nicolas Corvisart-Desmarets. A brilliant student, he became a member of the Societe d'Instruction Medicale.
René Laennec married quite late in his life. At the age of 43, he wed a widow, Jaqueline Argou, who had previously been his housekeeper. His wife soon became pregnant but suffered a miscarriage after a few months.
He was a very kind and religious person, known for his charity towards the underprivileged.
Never having enjoyed robust health, René Laennec was diagnosed with tuberculosis in April 1826. He died of the disease on 13 August 1826, aged just 45.
