QuickCheck: Did a dentist invent cotton candy?

Cotton candy (also known as candy floss) was invented in 1897 and made popular at the St Louis World Fair in Missouri, USA in 1904. It's now a popular treat the world over.

YOU probably do not talk to anyone about your teeth as much as you do with your dentist. Floss more, brush often, consume less sugar - we have heard it all.

But is it true that cotton candy - which is a spun sugar confection, often with some flavouring and colouring for added appeal - was invented by a dentist?
