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. He remembered a trick he learned as a child that sound travels through solids and thus he rolled up 24 sheets of paper, placed one end to his ear and the other end to the woman's chest. He was delighted to discover that the sounds were not only conveyed through the paper, but they were also louder and clearer.

The stethoscope was invented in France in 1816 by René-Théophile-Hyacinthe Laennec. It consisted of a wooden tube and was monaural. In 1851 Arthur Leared invented a binaural stethoscope, and in 1852 George Cammann perfected the design of the instrument for commercial production, which has become the standard ever since. Cammann also authored a major treatise on diagnosis by ascultation, which the refined binaural stethoscope made possible. By 1873, there were descriptions of a differential stethoscope that could connect to slightly different locations to create a slight stereo effect, though this did not become a standard tool in clinical practise.
Several other minor refinements were made to stethoscopes until in the early 1960's Dr. Littmann, a Harvard Medical School professor, created a new stethoscope with vastly improved acoustical performance.

No one really.Someone could take credit for the present design,I suppose.However,the real credit is lost in obscurity.Centuries ago when a person of royalty was ill a physician wanted to listen to her heart.No common doctor was going to lay HIS head on the breast of a queen or princess!The physician,being resourseful took a piece paper,rolled it into the shape of a cone and "voila!" the first stethescope!This worked so well it also became the design of the early hearing aid.
