Polish inventorsRudolf Gundlach
He is famous for his invention of the Gundlach Rotary Periscope (Polish: Peryskop obrotowy Gundlacha), patented in 1936, which made possible 360° vision. The periscope enabled an observer (e.g., the tank commander) to look forward (upper panel of the picture) or backward (lower panel) without moving his seat. Since it greatly increased the comfort of observer and widened the field of view, the new periscope design was used in virtually every tank built after 1940.Tadeusz Tański

Szczepanik held several hundred patents and made over 50 discoveries, many of which are still used today, especially in the motion picture industry, photography, and television.
Some of his ideas influenced the development of television, such as the telectroscope (an apparatus for distant reproduction of images and sound using electricity) or the wireless telegraph, which greatly influenced the development of telecommunications.
Szczepanik was granted awards by royal courts. Spanish ruler Alfonso XIII awarded him an order for creating the first ballistic vest.Kazimierz Prószyński
