As more than just a familiar fixture at Cracker Barrel and front porches across the nation, outdoor rocking chairs have a surprising history that was more a happy accident than thought-out invention. Indeed, it wasn't until the 18th century that the earliest forms of the rounded-bottom seats came into being. See how what began as a baby cradle and child's plaything in Europe has come to exemplify quaint American nostalgia.

Outdoor rocking chairs are also associated with some famous folks of yore. According to American legend, Benjamin Franklin is credited with inventing the rocking chair by taking a normal chair and adding rockers to it. Although Franklin is rightly attributed to a number of laudable inventions and ideas, this one unfortunately is completely untrue.

A number of presidents have been associated with the iconic chair as well, including McKinley, both Roosevelts and Eisenhower. However, none is more popular than that of John F. Kennedy, Jr. After incurring a war-related back injury, Kennedy turned to outdoor rocking chairs for relief. His reaction was so popular that he installed the chairs everywhere he went (including Air Force One). Not only did he boost the overall popularity of the chair, he also helped boost the career of wood artisan, Sam Maloof.

Most recently, New York Rangers' All-Star goalie Mike Richter also has connections to outdoor rocking chairs. After suffering a sports-related back injury, Richter approached woodworker Robert Erickson who handcrafted an ergonomically designed chair for the athlete. Today, ergonomic chairs are some of the most popular models on the market.

Nowadays, outdoor rocking chairs are about as American as apple pie, so it's interesting to think that their origins stemmed from across the pond. From the first rough designs, artisans molded and crafted unique styles of these iconic chairs into the shapes and styles we love and recognize today.
