Stethoscope was invented by René Laennec
The stethoscope was invented in France in 1816 by René Laennec at the Necker-Enfants Malades Hospital in Paris. -
The Piorry Stethoscope was invented by Pierre Adolphe Piorry
The Piorry stehoscope evolved to have a thinner stem without an extension piece and was about half the size of Laennec's. It was trumpet shaped, made of wood, and had a removable wood plug, ivory earpiece and chest piece. The ivory chest piece also served as a pleximeter. Most stethoscopes made after 1830 were modeled after the Piorry design. -
Monaural Stethoscope was invented by James Grumbridge
A presentation stethoscope given by Dr. James Hope to one of his exceptional medical students in 1839. It is made of cherry wood and ivory and modeled after the Piorry stethoscope. Dr. Hope designed an ivory ear piece that was curved so as to better fit the ear. The stethoscopes were made by James Grumbridge, a turner and stethoscope maker in London. -
Binaural Sethoscope invented by Cammann
An original Cammann stethoscope. The yoke of the hinge joint is hand engraved Dr. Cammann's Stethoscope and the reverse is stamped Tiemann N[ew]. York. This initial model had a large and flaring ebony chestpiece and ivory earpieces. The flexible woven tubes were covered with velvet and were very short as compared to later models. This stethoscope and the one above are the only two hand engraved Cammann stethoscopes known to exist. -
Stethoscope was invented by Maico Stethetron
The bells (the end of the instrument applied to patient’s body) have also become flatter. The application of electronic amplifiers to the stethoscope provided the next major modification. These stethoscopes amplified the sound heard by the physician and were capable of filtering high pitched tones in order to make faint tones louder. -
Stethoscope invented by Regency medicine
This year, 2016, is the 200th anniversary of the invention of the stethoscope. As with so many innovations, the stethoscope was not immediately welcomed by many Regency physicians. But then, so much of the medical knowledge we now take for granted was a mystery to doctors in the early nineteenth century.
