Most of us know that Louis Braille invented the Braille reading system that influenced how people with vision challenges can read.
But did you know there are other people who were blind that largely influenced the world around us today?
5 Influences made by People who were Blind
1. Dr. James Gale
Dr. James Gale invented a better way to make and store gunpowder that improved manufacturing and safety. He made gunpowder non-explosive until you add an igniter.
2. Ralph Teetor
Mr. Teetor was riding with his lawyer and the lawyer would slow down while talking and speed up while listening. This rocking motion so annoyed him that he wanted to invent a way to fix that. After ten years of work he developed the "Speedostat" which we know more commonly as cruise control.
3. Harriet Tubman
We all know our history about how Ms Tubman escaped slavery and then created the Underground Railroad. But did you know she did it all while nearly blind (from a hit in the head by a slave owner)?
4. Nils Gustaf Dalén
Thanks to this man, we can ride the train, subways and boats safely due to his invention of automated signal lamps and lighthouse lights.
5. Otto Weidt
In Nazi Germany Otto Weidt ran a shop that mostly employed Jews who were all disabled. He hired these people because he himself was blind. He often bribed guards or hid his workers from the Nazis, later he was posthumously recognized by Yad Veshem as “Righteous Among the Nations,” a non-Jew who risked everything to save his fellow man.
Another thing that I found touching about these people is that they disregarded their blindness as "not a factor in their lives" and lived independently, and even dangerously.
