How Did the Pigskin Get Its Shape?
How Did the Pigskin Get Its Shape?
The “pigskin” is not made of pig skin but is, in fact, made from cowhide. Of course, popular speculation has it that the leather exterior of the football was once made from the tanned skin of a pig, but it’s more likely that the football was made from a pig’s bladder. We may never know. Equally mysterious is the shape of the ball. If the sport evolved from soccer and rugby, how and when did the football gain its distinct shape - technically known as a prolate spheroid? Well, it turns out that the football was never truly designed, it just sort of happened. According to Henry Duffield, a man who witnessed a game between Princeton and Rutgers in 1869, largely considered to be the first intercollegiate game:
“The ball was not an oval but was supposed to be completely round. It never was, though — it was too hard to blow up right. The game was stopped several times that day while the teams called for a little key from the sidelines. They used it to unlock the small nozzle which was tucked into the ball, and then took turns blowing it up. The last man generally got tired and they put it back in play somewhat lopsided.”
So according to that story, the football that bounces erratically all over a field and can fly through air in a perfect spiral is not, in fact, the product of high design. At least not initially. Rather, it’s the result of a leaky sphere and some lazy inflaters. Initially, football was a very different game - or perhaps I should say games. There were kicking games and running games, but as those two games began to merge together, as rules began to standardize, the ball began to slightly stretch out in order to accommodate more types of use. The unique shape of the ball was somewhat formalized in the early 20th century and that form was exploited to great success when the forward pass was introduced to football in 1906
