Who invented the Stethoscope ?

René Laennec

The stethoscope was invented in 1816 when a young French physician named Rene Theophile Hyacinthe Laennec was examining a young female patient. Laennec was embarrassed to place his ear to her chest ( Immediate Auscultation ), which was the method of auscultation used by physicians at that time.
