Note Type: Historical
Notes: Rene Laënnec, a French physician, devised the first stethoscope in 1816. His
early stethoscopes were longer than the version described and illustrated in
his 1819 text: De l’Auscultation Me´diate. The lineage of modern equipment
used to monitor patients’ vital signs during anesthesia can be traced back to
the early wooden stethoscopes. The familiar binaural stethoscope became
common in the 1850s.
