The paperclip was invented in 1899 by Johan Vaaler. He received an American patent in 1901. ;)
There are some articles talking about this in Wikipedia, but as I heard from my teacher who has lots of knowledge, it was invented by a child who was in school, playing with a piece of thin metal, and when he turned in his homework, he twisted it around and used it as a paperclip that's used these days. I'm pretty sure that the paperclip the child made didn't look exactly the same as today's paperclip.
