National Inventors’ Day

Inventions play a vital role in shaping modern life. Thanks to the creativity and dedication of engineers, chemists, physicists, and biologists, our daily existence has become more comfortable and advanced. National Inventors’ Day was established to honor those who have made remarkable contributions through invention.

History

National Inventors’ Day was established in the United States in 1986, initiated by President Ronald Reagan. The date—February 11—was chosen to commemorate the birthday of renowned American inventor Thomas Edison.

Few people today consider what life was like before inventions such as the microwave oven, washing machine, light bulb, or telephone. These innovations are so deeply woven into daily life that we often forget about the brilliant minds behind them. Thanks to inventors, humanity has learned to fight diseases, control epidemics, explore space, and communicate over long distances. Lighting a room or contacting someone is now as easy as flipping a switch or making a call.
