Aldo Cambell

Next Inventor's Day, take a moment to remember the great creative folks who were martyred while trying to make the world a better place. Take, for instance, Aldo Cambell (1811-1845), an acoustical engineer of unparalleled talent who was killed by an angry mob for having the temerity to attempt to bridge the divide between his Swiss and Scots ancestries by producing a yodeling bagpipe.

No examples of his crowning achievement are known to exist, although there are persistent rumors that the Vatican's Office of the Holy Inquisition has one locked away in case they ever need a true terror weapon.
