The dentist who helped invent cotton candy

Create the problem, sell the solution. In 1897, dentist William Morrison teamed up with a confectioner to invent a machine that spun pure sugar into delicious, cavity-inducing clouds originally called 'Fairy Floss.' He debuted it at the 1904 World's Fair, sold tens of thousands of boxes, and presumably spent the next decade happily drilling the rotting teeth of his own satisfied customers.
