Manuel Garcia's invention of the laryngoscope in 1854 set off a period of profound research. German and French scientists—physicians, physiologists, physicists, and voice teachers—spared no efforts in their study of the vocal organs and their functions.In 1905, Gutzmann,1,2 lecturing at the University of Berlin, repeated and further explained Johannes Müller's experiment demonstrating that falsetto function of the voice was seen to involve "free-edge" vibration of the vocal cords and that this could be visualized in the postmortem larynx; further, that "full" vibration of the cord corresponded to the "fundamental" tone of the voice teachers and was due primarily to thyroarytenoid muscle function.The postmortem larynx was mounted as shown in Figure 1.1.
