How the stethoscope was invented | Moments of Vision 7 – Jessica Oreck

In a Moment of Vision… It’s 1816. A 35-year-old doctor by the name
of René Laennec is walking through Paris. He pauses to watch as two children
signal to each other across a long piece of wooden board. One child holds the board to her ear. The other scratches the opposite end sending the amplified sound
down the length of wood. Later, Laennec is called to assess
a young woman with a heart condition. The patient is purportedly quite
well developed and Laennec expresses some hesitation in pressing his ear directly
against her chest. Remembering the children with the board, Laennec, in a moment of vision
and dignity, tightly rolls a sheet of paper and places one end to his ear and one end over the young
woman’s heaving bosom. He is delighted by
the clarity of the sound. Laennec spends the next three years
developing and testing various materials and mechanisms before settling on a hollow wooden tube
with detachable plug. His device becomes the forerunner to the metal, plastic, and rubber
stethoscope we still use today.


  1. As interesting as the stories may be, I always find it rather difficult to follow the narration, as the pictures are way too distracting. In my opinion, the purpose of a video should be to convey one single subject via both narration and pictures at the same time. But with this video series, you basically show us how to craft certain object and tell us the story behind them. No wonder there are always a lot of people in the comments telling you that they need to watch the video twice.

  2. That's pretty cool. Don't think many people really think about the origin of some medical instruments. Now we know! haha

  3. You know, this is what we need: "In a moment of dignity…" – a series about people making the right thing even when they have a choice.

    Seriously, this guy wasn't even tempted.

  4. I always wonder, how are there dislikes on a video about history. like, this is how it happend, NO I DO NOT LIKE THIS! what

  5. Wait, so the stethoscope was invented because a doctor was shy of nuzzling his cheek into someone's chest, not out of any functionality necessity?

  6. The origami or whatever it called is more interesting than the story of a well-behaving virgin invent something with child play.

  7. Why is the music so loud? Why is there music? It's off putting, especially as I'm hearing impaired. Please stop with the unnecessary noise!

  8. I do understand Mr. René. May be that the woman in question is not so pretty or her skin may be dry or peeling off or even her "bosom" may not be to his taste.
    Thank you for this video.

  9. You loose your diginity if you press your face against the mighty boobs of a young woman??? Whaaaat? which century are we in?

  10. Why the quality of these videos has decreased so much? No funny and entertaining animations anymore, just timeframe videos. There is no budget or what? Really crappy, make a podcast instead.

  11. Lot of insecurity and projection in here. The guy was a doctor, I guarantee he did not think of himself as some kind of loser.

  12. I kinda wish people would just listen to the fact that a great medical tool was invented…I'm pretty sure it's a GOOD thing when a doctor respects both his own boundaries, and his patient's privacy, and it's even cooler when a useful invention comes from it.

  13. Bad video! Doctors didn't mind that much getting near a woman's breasts, stethoscopes were made because it was unpractical to put a rag between the doctor and the patient every time the doctor listened to the heart. And because listening to an obese person's heartbeats was hard with all the fat there. Get informed correctly!

  14. I grew up in an antique drug store to witch is the proud owner of a hallow cylinder of wood that would have been used to monitor the pulse of a heartbeat. Primitive yet effective.
