This very early exemplar (c. 1819) of the monaural stethoscope devised by RenĂ© Laennec can be seen in the Warren Anatomical Museum of Boston. This stethoscope, curiously displayed inside a top hat, “is a solid wooden cylinder with a drilled center that could be unscrewed for carrying in the pocket, At one end, a chest piece auscultated the heart and when removed, the large opening was for listening to the lungs. By the 1850s, the monaural stethoscope was a mainstay of the physical examination”1.
