There are two examples that illustrate how inventions sparked by small inconveniences can revolutionize everyday life. The pneumatic tire by Dunlop and the rubber eraser both invented in 19th century England were born from the pursuit of safety and convenience and are still widely used today.

An Invention for His Son’s Safety: Dunlop’s Pneumatic Tire

In 19th century England John Boyd Dunlop a veterinarian and mathematician invented the pneumatic tire following a bicycle accident involving his son Johnny. At the time bicycle wheels were mostly made of metal causing severe shaking and a high risk of accidents on rough roads. After witnessing his beloved son fall and get injured while riding a bicycle Dunlop felt a strong need for safer wheels.

Dunlop inspired by watching his son play with a soccer ball came up with the idea of making a rubber tire filled with air for bicycle wheels. He wrapped the bicycle wheels with rubber and injected air into them creating a resilient tire that absorbed shocks. This invention greatly improved the stability of bicycles and Dunlop soon established a tire company to expand his business. With the advent of automobiles his pneumatic tire achieved worldwide success and remains an essential component of both cars and bicycles today.

An Invention Born from a Mistake: Priestley’s Rubber Eraser

The invention of the rubber eraser originated from a small mistake. In 1770 British chemist Joseph Priestley was writing at his desk when he accidentally discovered the eraser by rubbing out his writing with a piece of rubber. Upon noticing that the rubber erased the writing on paper he realized that this material could serve as an eraser.

Priestley utilized the rubber’s ability to absorb graphite particles from pencils to create the first rubber eraser which later became widely known as “rubber.” The name “rubber” was derived from the English word “rub” reflecting the action of erasing and this term is still used today.

These two inventions were born from everyday inconveniences and accidental discoveries and they continue to make our lives more convenient. The moments of invention often come from unexpected places demonstrating that small concerns for solving everyday problems can change the world.
