Littmann stethoscope

Invention of the combination stethoscope

The name Littmann is known worldwide in the medical field for the stethoscopes he developed. He described his “ideal stethoscope” to his colleagues in the November 1961 issue of the Journal of the American Medical Association .

His invention of the “combination stethoscope” consists of a double-headed chest piece with a funnel on one side and a membrane on the other. Since then, it has made it easier to hear high and low frequency sounds. In 1963 he applied for a patent for his development .

Together with Gus Machlup, Littmann founded Cardiosonics for the sale of stethoscopes, initially only a nurse's and a doctor's testethoscope were offered. In April 1967 3M took over Littmann's company and kept the founder as a consultant. 3M still produces stethoscopes under the name 3M Littmann.
