The first stethscope was invented in 1816 by a French physician whos names was Rene Theophile Hyacinthe Lanennec. He invented this because when he had a female patient he was embrassed to put his head on her chest to listen to it. This was at the time the auscultation that was used by physicians at the time. So instead of Lanennec doing this is remember that when he was a kid that sounds travel through solids. So he used 24 pieces of rolled up paper to listen to the patient. He put one end on her chest, and he listen on the other end with his ear. The sounds of her chest were load and clear even through a paper cone.
The word stethoscope came from Greek words meaning "I see and the other one is "the chest. This stethoscope was made from wood that was turned on a turn table at Laennec house. It had a hollow bore in the center of it . It was two pieces one end was for ear and the cone funnel looking piece was to be placed on the chest. The picture above is Laennec first stethoscope that he made. Pictures below are one is the old way people would listen to the chest and the other way is the first stethoscope being used.
