t is believed that the yo-yo most likely originated in China. The first historical mention of the yo-yo, however, was from Greece in the year 500 B.C. These ancient toys were made out of wood, metal, or painted terra cotta disks and called just that, a disc. It was customary, when a child turned of age, to offer toys of their youth to certain gods. Due to the fragile nature of the material, it is presumed that the disks made of terra cotta (clay) were used for this purpose rather than for actual play. A vase painting from this time period shows a Greek youth playing with a yo-yo. Such vases, as well as an actual terra cotta disk can be found in the National Museum of Athens, Greece.

Even in ancient Egyptian temples, drawings of objects have been seen in the shape of yo-yos.

Historical records indicate that 16th century hunters in the Philippines hid up trees and used a rock tied to a long cord, up to 20 feet in length, to throw at wild animals beneath them. The weapon was able to be pulled up and thrown back down for multiple attempts at the prey. This gave rise to the widespread idea that the practice was the true forerunner of the yo-yo, but this is a stretch of imagination and has no real basis in fact. It is extremely likely, however, that the yo-yo did travel from China not only to Greece, but also to the Philippines, where the yo-yo is known to have been a popular toy for children over a very long period of time.

The next historically dated mention of the yo-yo is a box from India made in the year 1765. This miniature box was hand-painted with the picture of a girl in a red dress playing with her yo-yo. Within the next 25 years, the yo-yo traveled from the Orient to Europe, specifically to the aristocracy (upper class) of Scotland and France and on to England. As it traveled, it became known by a variety of names.

In France, a painting dated to 1789 shows the 4 year-old, future King Louis XVII holding his l'emigrette. It was during this time of the French Revolution and the "Reign of Terror," that many of the French aristocracy were forced to flee to Paris, Germany and across other borders when their style of life was threatened by the peasant uprisings, taking their popular yo-yos made of glass and ivory with them. L'emigrette is a French term meaning to 'leave the country.' Another nickname for the yo-yo at this time was de Coblenz, which was a city to which many French fled. These names reflect an important historical connection between the toy and the French Revolution.

The yo-yo's value as a stress reliever is also seen through history. While being a fashionable toy for the French nobility, those less fortunate are said to have played with their emigrettes to reduce the understandable tension of their one-way trip to the guillotine. Dating through the 1780's, there are drawings of General Lafayette and others with their troops flinging their yo-yos. The yo-yo arrived in Paris in 1791 as it spread through France and was called the "joujou de Normandie." Some believe that this term may reflect possible roots for the modern American name of "yo-yo." High interest in the toy continued as evidence by the famous French playwright, Beaumarchais, in his treatment of "The Marriage of Figaro" in 1792. There is a scene where the nervous Figaro enters and conveys his tension, not by the conventional wringing of this hands, but playing with his emigrette! When asked what the emigrette is good for, Figaro responds, "It is a noble toy, which dispels the fatigue of thinking." Even on June 18, 1815, at the famous Battle of Waterloo, Napoleon and his army are known to have been seen relaxing with their yo-yos before battle.

The yo-yo craze traveled throughout Europe to England by way of Scotland and France. The English used the French word bandalore, the term quiz, and the word incroyable which means 'a French dandy', to identify the toy. In 1791, a print was circulated of the Prince of Wales, future George IV, whirling his bandalore. Because of the toy's popularity as well as the prince's power to sell, the toy also became known as the Prince of Wales' toy and soon became a toy that any person of fashion had to own. The toy's ongoing popularity in England is shown as late as 1862 when an illustration appeared showing two young lads terrifying an older woman with their quizzes.

The first recorded reference to any type of yo-yo in the United States was in 1866 when two men from Ohio received a patent for an invention called "an improved bandalore," in that it was rim weighted. One year later, a German immigrant named Charles Kirchof patented and manufactured the return wheel. From then until 1911, although various patents were awarded in the United States related to the yo-yo, nothing notable occurred. In 1916, the Scientific American Supplement published an article titled "Filipino Toys: which showed it and named it a yo-yo. This was explained by some as the Filipino word for "come-come" or "to return." Significant events were soon to happen in the United States.

Meanwhile, back in the Philippines, the natives were becoming experts at making and using the toy. They became excellent wood carvers of the yo-yo and playing with a yo-yo, beginning early in childhood, became a national pastime. Not surprisingly, it was from here that the yo-yo as we know it today was truly introduced into the United States. In the 1920's, a man named Pedro Flores brought the first Filipino yo-yo to the U.S. and in 1928, began a yo-yo company by the same name in California.

These yo-yos were hand-carved from a single piece of wood. The yo-yo was unique because it was the first yo-yo that did not have the string tied to the axle. Instead, the string was looped around the axle, allowing the yo-yo to spin or "sleep" at the end of the string. This concept is at the heart of yo-yoing today. Rather than being able to only go up and down, the yo-yo was now capable of doing an infinite number of tricks.

In 1928 or 1929, a businessman named Donald F. Duncan Sr. saw his first Flores yo-yo while he was in San Francisco. He saw the potential of the toy as he witnessed the crowd that Pedro was able to draw by doing a few tricks. He purchased not only the idea of the yo-yo, but the Pedro Flores company itself. And, as they say, "the rest is history."

Donald Duncan was an excellent businessman. He developed advertising campaigns and had demonstrators working for him in the U.S., as well as Western Europe. "Duncan Yo-Yo Professionals" traveled throughout the United States teaching and demonstrating yo-yo tricks and conducting contests in an effort to promote sales. Competition grew as other companies began to see the toy's potential. In 1932, in an effort to protect his interest, Duncan filed for and was assigned a trademark for the work "yo-yo." Not able to use the term "yo-yo," competitors were forced to use terms like "come-back", "return", "returning top", "whirl-a-gig", and twirler" for their versions of the toy.

In 1946, the Duncan company moved to Luck, Wisconsin, which quickly became known as the "Yo-Yo Capital of the World" producing 3,600 yo-yos per hour. They produced the original maple wooden yo-yos using 1,000,000 board feet per year. In 1960, plastic yo-yos that we still see today began to be manufacture. Sales grew and grew. By 1962. The Duncan Company alone sold a record 45 million yo-yos in a country with only 40 million kids, and still cold not keep up with the demand. High television advertising expenses and excessive expenses in overtime wages and materials to keep up with the demand hurt profits. There was also the continual legal expense in trying to hold onto the trademarked word "yo-yo." Competitors fought hard to use it in describing their products. Finally, in 1965, the Federal Court of Appeals ruled that Duncan's trademark for the word "yo-yo" was no good. The term yo-yo had become so widespread that it was now a permanent part of the language and it no longer only described the toy. It, in fact, WAS the toy.

Tragically, in November of 1965, the Duncan Company could hold on no longer and was forced into bankruptcy. Although pieces of equipment were auctioned off to various buyers, Flambeau Plastics Company purchased the most valuable asset, the "Duncan" name and the goodwill that came along with it. It is the Flambeau Plastics Company that manufactures and sells the eleven different models of Duncan yo-yos today. June 6 has been deemed National YoYo Day in honor of Donald Duncan Sr.'s birthday and the phenomenal influence he had in the world of YO.

Trivia enthusiasts will enjoy noting that in 1968, Abbie Hoffman was cited for contempt of Congress for "walking the dog" in an effort to entertain the House Subcommittee on Un-American Activities that was investigating him and Richard Nixon made headlines when he yo-yoed on stage at the opening of the Grand Ole Opry in Nashville in 1974. The yo-yo is, indeed, universal.

In recent years, technology has affected a multitude of the products we use, and the seemingly simple yo-yo has been no exception. Beginning in the 1970's, yo-yo manufacturers, seeing the benefit of periphery weight distribution, began rim-weighting their products for a longer spin. In 1978, Tom Kuhn patented the "No Jive 3-in-1" yo-yo, the first take apart by hand yo-yo and the first having a replaceable axle. In 1980, Michael Caffrey patented "The yo-yo with a Brain." In addition to a free-spinning sleeve bearing for long spin times, "The Brain" has a centrifugal spring loaded clutch mechanism that causes an automatic return of the yo-yo to the hand when the rotational spin slows to a pre-determined rate. And by the 1990's, transaxle yo-yos were available with ball-bearing axles, increasing spin times once again.

But this is not quite the end of the story. On April 12, 1985, the yo-yo was first taken into space by NASA on the Space Shuttle Discovery as part of the Toys in space project. A basic spinning yo-yo was used to see what effect microgravity would have on it. What they discovered was that a yo-yo could be released at slow speeds and gracefully move along the string. However, the yo-yo refused to "sleep." Without the downward force of gravity, the yo-yo could not spin against the loop at then end of the string and so, rebounded up the string. It was also found that the yo-yo must be thrown, not dropped, as there was no gravity to pull it down. And on July 31, 1992, the yo-yo (an SB-2) again made its way into space, on the Space Shuttle Atlantis, this time for an educational video including slow-motion YO-Yoing.

Whether the yo-yo was a Chinese, Greek or Filipino invention or some combination is difficult to prove. By the same token, it is also difficult to say with certainty whether the same basic pattern for the toy appeared in completely different parts of the world for no obvious reason. We do know that its use as a toy around the world and throughout history is unmatched. And, although the yo-yo has gone through periods of hibernation in its trek through the ages, its popularity, just like the toy itself, always comes back.
