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.
