Holes
When was the hole puncher invented?
The first patent for a hole puncher, or Papierlocher für Sammelmappen (paper hole maker for binding) was filed on 14 November 1886 by inventor Friedrich Soennecken.
Mr Soennecken was a German office supplier from the town of Remscheid who founded his own company, F Soennecken Verlag, in 1875.
His wares quickly became renowned for their quality, and his paper and pens were a favourite of German philosopher Freidrich Neitzsche, the man who coined the phrase: "What does not kill me makes me stronger".
As well as inventing the hole puncher, Mr Soennecken created the ring binder to store the freshly punched sheets and a style of calligraphy designed to be neat yet standardised and easy to learn.
The hole puncher's design has not changed much in the 131 years since its invention.
