The stethoscope was originally developed in France by René Laennec at the Necker-Enfants Malades Hospital in 1816. The unit at that time consisted of a wooden tube and was resembled an ear trumpet which had been used as a type of hearing aid. Since it had a single tube, it was monaural. In 1851, the stethoscope was additionally refined by Arthur Leared who created binaural model. Finally in 1852 George Cammann perfected a design which could be automated in high volume and which became the standard for units to follow.
In the 1940′s a futuristic type of stethoscope was developed by Rappaport and Sprague which became the one by which all other stethoscopes were reviewed[spin]. It [spin]featured a two sided head – one was used for measurement of the respiratory system and the other side for the cardiovascular system. This design was later produced by HP Medical Systems.
Several enhancements were made and in the early 1960s Dr. David Littmann, a Harvard Medical School researcher, created a new stethoscope that was lighter than previous models and had enhanced sound sensitivity. He continued to improve his design and in the late 1970s, 3M-Littmann introduced the tunable diaphragm which is a cornerstone of the Littmann models today.
Littmann stethoscopes are designed by 3M Healthcare. The Classic II model is the most sought after model in the Littmann lineup and valued for its workmanship and flexibility.
