Dr. Littmann's Legacy

brief history the stethoscope

Advancing the art of listening through the years.

When French physician René Laënnec invented the first stethoscope in 1816, it was simply a rolled-up paper tube that funneled sounds from his patients’ chest to his ear. It was not until the early 1960s that Dr. David Littmann, M.D., (1906-1981), would patent a revolutionary new stethoscope design that was lighter, more convenient to carry and use, and with vastly improved acoustical performance.

In this timeline, see how Dr. Littmann’s legacy has provided medical professionals like you with consistent high acoustic performance, as well as enhanced comfort for your patients.
