The first stethoscope, invented by René Laennec in 1816, was a simple, monaural design made from a long wooden tube. It resembled a Trumpet and was used to amplify sounds from the heart and lungs. Laennec initially used it to listen through a rolled-up piece of paper before creating the more structured design, which allowed for better sound transmission. This early version marked the beginning of modern auscultation techniques in medicine.
