The invention of the stethoscope


04 Dec The invention of the stethoscope

The stethoscope was invented in France in 1816 by René-Théophile-Hyacinthe Laennec, who was inspired by a coiled notebook he used to listen to a patient’s heartbeat. The stethoscope was subsequently improved to a 12” cylinder made of wood with a 2 mm diameter hole. In 1851, Arthur Leared invented the binaural (double) stethoscope, whose shape was further improved in 1852 by George Camman for mass production purposes, finally arriving at the instrument we know today.
