History

National Open an Umbrella Indoors Day was created by T. E. Knibb, who wanted to dedicate one day a year to exploring this long standing superstition. The idea behind the observance is to encourage people to try it for themselves and see whether anything unusual happens.

According to researchers, umbrellas originated in ancient Egypt. Early umbrellas were constructed from sticks covered with leaves and were used primarily to provide shade. In China, umbrellas evolved into a form more similar to modern designs, with thick paper used for the canopy.

Umbrellas intended for rain protection appeared in the mid 1800s. Inventor S. Fox patented a design featuring a metal frame with spokes and water repellent fabric, which eventually led to the umbrellas we use today.

Interesting Facts
