Inventor's Day in German-Speaking Countries

Inventor’s Day in German-Speaking Countries: November 9th

November 9th is Inventor’s Day in Germany, Switzerland and Austria.

Inventor’s Day is a memorial day established in various regions to celebrate the achievements of inventors.

In Germany, Switzerland, and Austria, which are generally known as German-speaking countries, November 9th is the inventor’s day.

This is due to the birthday of Austrian-born Hollywood actress Hedy Lamarr who invented “Frequency-hopping spread spectrum” in 1942 on November 9th.

It was declared by the German inventor Gerhard Mutenthaler, whose main purpose is to make existing ideas better and to remember the inventors of the past.
