In the 18th century, this is how doctors listened to their patients’ hearts.

It was a method called direct auscultation, which is just a fancy way of saying putting your ear to the patient’s chest and listening.

However, René Laennec, a doctor in Paris, felt ill at ease putting his head directly on the chests of his female patients. So he rolled up a piece of paper and found it amplified the heartbeat quite nicely.

He tinkered with the idea and in 1816 came up with this.

He called his new invention the stethoscope, from the Greek, “to examine the sternum.”

Laennec died ten years later of tuberculous, which his nephew diagnosed using his uncle’s invention.

Today studies have shown that the presence of a stethoscope increases the odds of a doctor being rated trustworthy by patients more than any other medical instrument.
