The stethoscope was the brainchild of René Laennec at the Necker-Enfants Malades Hospital in Paris, France who invented the first ever “Steth” back in 1816. It was a wooden tube-like listening device, which he invested as he didn’t feel comfortable putting his ear directly onto a woman’s chest. Irish physician Arthur Leared invented a binaural stethoscope in 1851, and George Philip Cammann later perfected the design of the stethoscope instrument, which used both ears, for commercial production.
It was in the early 1960s that a Harvard Medical School professor named David Littmann, created a new stethoscope that was lighter than previous models and had improved acoustics. Introducing a tuneable diaphragm in the late 1970s, the gold-standard in Stethoscopes was born.
Used today by Medical & Veterinary Professionals around the world, 3M™ Littmann® Stethoscopes are the pinnacle of innovation and deliver the optimised acoustic performance for you and your patient (whether they are human or animal!)
