Origin of National Rubber Eraser Day
It was on April 15 in 1770 that a noted scientist Sir Joseph Priestley discovered a vegetable gum rubbery substance, known now as the eraser. Since then, April 15 is celebrated all over the globe as National Rubber Eraser Day in order to acknowledge the invention of eraser, thanks to Sir Joseph Priestley for the nice little plug that sits atop our pencils and does magical works.
Why we do not just call it an "Eraser Day"?
You might be thinking why we do not call April 15 as an Eraser day? There are two main reasons behind it. First of all, the first erasers were basically made from rubber, an elastic polymeric substance. Secondly, erasers are formally called “rubbers" in Great Britain - the hometown of Joseph Priestley, who is the inventor of rubber eraser.
