Story of a Medical Discovery !!

 It is obvious to see while visiting a doctor that most of them will have hanging on their neck and that is 'Stethoscope'. It is an acoustic device to listen to the internal sounds of the body, especially the heart sound, the breath sound and the bowel sound.

Do you know how it was originated in real?

Dates back in 1816 and the credit goes to renowned French doctor Rene Laennec for this great invention. 

Doctor Rene Laennec was extremely shy to bring his ear closer to the chest of his patients and at times he felt more embarrassed to do so. To avoid such awkward situation he tried discovering something which will allow him not to bring his ear closer to the patient's chest.

And he created a cylinder 30 cm long for the purpose; it was indeed the first "Stethoscope" in any form. Of course we in modern times, the stethoscope has taken its revolutionary changes in appearance.
