Ooh, doctor!

Did you know that the stethoscope was invented out of a sense of embarrassment? A doctor in Paris in 1816 became uncomfortable with the fact that in order to listen to the heart-beat of a woman, he had to put his ear to her bare breasts, so he came up with something akin to an ear trumpet which allowed him to listen to her heart without the necessity of physical contact.  And it developed from that.
