Who was the first man who invented yoyo?

The Chinese invented the toy in about 1000 BC. Freely available on the trade routes, the device found it's way to the Phillipines where it was named yo-yo (come back) and used as a weapon in the 16th century. In the early 20th century, re-marketed as a toy, the YO-YO manufacturing company was formed in Santa Barbara CA by Phillipines buisnessman Pedro Flores.
