Science Diction: The Origin Of 'Stethoscope'

The first stethoscope, invented by the French physician René Laennec, was simply a hollow wooden or ebony tube. Laennec named the device using the Greek roots stethos, or chest, and skopein, to look at or to observe. Medical historian Howard Markel discusses how Laennec came up with the invention.
