While visiting Tarnow this summer, I saw an exhibit about Jan Szczepanik, often called the Polish Edison.
I must admit I'd not heard of him before.
Why should we care? Well, have you watched television today? Have you seem a film in the past few days? Have you enjoyed pictures of your family or recent vacation? All of these things are possible because of Szczepanik. In his life time Szczepanik acquired several hundred patents for his inventions, primarily in the areas of color photography, television transmission, and color films for motion pictures.
However, he also invented the first ballistic vest and was honored for this by Alfonso XII of Spain. One story says Alfonso's life was saved by the wearing of this vest.
It's amazing what one can learn taking a walk around town. I really enjoy how Poland museums put displays up in public spaces such as the market areas, so one can learn outdoors!
