René Laennec

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.

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 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.

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.
