Unlike most doctors, French physician René Laennec was also a skilled musician. It was while making his own wooden flutes that he invented the stethoscope, which helped doctors examine the chest cavity through auditory cues. His research also included work on melanoma, cirrhosis, and tuberculosis. He was a dedicated Catholic.
