National Inventors Month – May 2025

National Inventors Month, observed every May, celebrates human ingenuity. If it weren’t for the creativity of inventors through the ages, we would still be traveling on horseback, writing with quills, and heck, tediously cutting a loaf of bread every morning. That’s right. Someone came up with the idea of sliced bread, the breakfast staple we all take for granted. Most objects we see around today were the brainchildren of folks who thought out of the box. Here’s to the imaginations and courage of all inventors!

History of National Inventors Month

National Inventors Month started as a collaboration between the United Inventors Association of the USA (UIA-USA), the Academy of Applied Science, and “Inventors Digest”.

First recognized in August 1998 to celebrate creativity, ingenuity, curiosity, and the courage to experiment, National Inventors Month has continued to recognize the talented individuals who have changed history through their inventions.

Then, in 2011, the decision was made to move National Inventors Month to May to coincide with the annual National Inventors Hall of Fame ceremony as well as to better align with the academic calendar. Celebrating inventors in May allows teachers the opportunity to encourage innovation and creativity through invention while students are still in class. This is the time to draw attention to the contributions of men and women across the world and across the centuries.

Since 1973, the National Inventors Hall of Fame has inducted over 600 individuals. This elite group of individuals are nominated and selected based on: (1) the inventor holds a US patent, (2) their invention has made a significant contribution to society and/or their industry, (3) the inventor has persevered to overcome obstacles in their journey, and (4) the inventor is also seen as a leader in their field contributing to future generations of American inventors.
