The stethoscope has remained relatively unchanged since the 1930's. There have been, however,
several different experimental stethoscopes. The most notable of these is the
'SYMBALLOPHONE' of Dr. William Kerr in the 1940's. This was very similar to Alison's
differential model, but used two diaphragms rather than bell chest-pieces.

The newer models have both the bell and diaphragm interchange able in the same
chest piece. The
hallmark of the physician, the stethoscope opened new worlds to the art of diagnosis, and remains
the most valuable diagnostic tool available and the rest, as they say ......... is history.
