In 1826, the French physician Rane Theoplhie Hyacinthe Laennec (1781-1826) introduced a perforated wooden cylinder which concentrated the sounds of air flowing in and out of the lungs, and describe the sound which it revealed. The modern form of Stethoscope, with flexible tubes connecting the earpiece to a circular piece placed against the chest, was developed later in the nineteenth century.
