Here are a few stethoscopes that were photographed after my lecture in Indianapolis.
I would like to thank the Indiana Medical Museum for the privilege of allowing me to photograph these instruments.
This stethoscope is a Gammon binaural presented to a G.W. Trump M.D. in 1869
early monaural Laennec style stethoscopes a Pilling stethoscope from the 1920's
I suggest that anyone visiting Indianapolis to take the time to enjoy this wonderful facility.
