It's said that the invention of the stethoscope was driven by Dr. Laennec's embarrassment at having to press his ear against the chests of female patients.
And if you ever need to remember who invented the stethoscope: just remember that he was French, and that his invention goes round 'la neck'. (Thanks to former Mastermind champion Liz Horrocks for this.)
