Fascinating facts about the invention
of the
Yo-Yo by Donald F. Duncan in 1928.
The yo-yo has enjoyed many periods of popularity throughout world history and may be the second oldest toy in the world (after dolls). There are ancient Greek yo-yos made of terra cotta in museums in Athens and yo-yos are pictured on the walls of Egyptian temples. The Yo-Yo is known to have been popular with such important warriors as Napoleon and the Duke of Wellington. First patented in 1866 by James L. Haven and Charles Hettrich, the Yo-Yo has enjoyed periods of popularity for generations with kids from 1 - 100.

The modern story of the yo-yo starts with a young gentleman from the Philippines, named Pedro Flores. In the 1920s, he moved to the USA, and worked as a bellhop at a Santa Monica hotel. Carving and playing with wooden yo-yos was a traditional pastime in the Philippines, but Pedro found that his lunch break yo-yo playing drew a crowd was the first appearance of the name "yo-yo," which means "come-come" in the at the hotel. He started a company to make the toys, calling it the Flores Yo-Yo Company.

Donald F. Duncan, an entrepreneur first encountered the yo-yo during a business trip to California. A year later, in 1929, he returned and bought the company from Flores, acquiring not only a unique toy, but also the magic name "yo-yo." About this time, Duncan introduced the looped slip-string, which allows the yo-yo to sleep - a necessity for advanced tricks.
During the 1950s, Duncan introduced the first plastic yo-yos and the Butterfly® shaped yo-yo, which is much easier to land on the string for complex tricks. The biggest yo-yo boom in history hit in 1962, following the innovative use of TV advertising. Financial losses at the end of the boom, and a costly lawsuit to protect the yo-yo trademark from competitors forced the Duncan family out of business in the late 60s. Flambeau Products, who made Duncan’s plastic models, bought the company and still owns it today.

Steve Brown is granted U.S. Patent #6,371,824 for "Yo-Yo, and Method for Using a Yo-Yo". The patent covers the Freehand counterweight system, and is assigned to Flambeau Products, the parent company of Duncan Toys. Steve spends a full two days jumping up and down with glee
