As is well known by now throughout the world Harvey Ball, a commercial artist from Worcester, Massachusetts created the smiley face in 1963. That image went on to become the most recognizable symbol of good will and good cheer on the planet.

As the years passed Harvey Ball became concerned about the over-commercialization of his symbol, and how its original meaning and intent had become lost in the constant repetition of the marketplace. Out of that concern came his idea for World Smile Day. He thought that we, all of us, should devote one day each year to smiles and kind acts throughout that world. The smiley face knows no politics, no geography and no religion. Harvey’s idea was that for at least one day each year, neither should we. He declared that the first Friday in October each year would henceforth be World Smile Day.

The very first World Smile Day took place in Worcester, MA on October 1, 1999. What a celebration it was! State and local dignitaries gathered and read proclamations in support of the day. Another proclamation recognizing the day was read on the floor of the United States Congress and is now part of the Congressional Record, the reporter of the official proceedings of the US Congress. Thousands of Worcester school children created World Smile Day cards that were then delivered to area hospitals and nursing homes. The event became national and even international news.

The US Postal service came to Worcester that day to unveil its new Smiley Face stamp design. And, the Postal Service issued a special cancellation just for that event. Each year since then the USPS has issued a different cancellation commemorating the day.

In his inaugural address on that very first World Smile Day Harvey Ball laid the groundwork for that World Smile Day saying that the smiley face “…just reflects what is inside every one of us – a smile is what we want to see when we look at another human being.” He said, “Sometimes we forget that. Sometimes the world seems big and filled with problems that are too hard to understand much less solve. We start to believe that we are too small to make a difference. But that’s not true. The truth is that every one of us has the ability to make a difference every day.”

Harvey's hometown of Worcester, MA has been and continues to be the epicenter for World Smile Day.
