It was not until the 1920s that Americans first heard the word yo-yo. Pedro Flores, a Philippine immigrant, began manufacturing a toy labeled with that name. Flores became the first person to mass-produce yo-yos, at his small toy factory located in California.
Duncan saw the toy, liked it, bought the rights from Flores in 1929 and then trademarked the name Yo-Yo.
Biography of Pedro FloresPedro Flores was born in Vintarilocos Norte, Philippines. In 1915, Pedro Flores immigrated to the United State and later studied of law at the University of California Berkeley and the Hastings College of Law in San Francisco.
Pedro Flores never completed his law degree and began his yo-yo business while working as a bellboy. In 1928, Flores started his Yo-Yo Manufacturing Company in Santa Barbara. James and Daniel Stone of Los Angeles financed machinery for the mass production of yo-yos.
On July 22, 1930, Pedro Flores trademark registered the name Flores Yo-Yo. Both his yo-yo factories and the trademark were later acquired by the Donald Duncan Yo-yo Company.
