Periscopes have been around for quite a while. In the 1430s, a predecesor to the periscope was invented by Johannes Gutenberg so pilgrims could see over the heads of crowds at religious festivals.
The concept was further developed in the 1640s by Johannes_Hevelius with what he called a "polemoscope". By the 1800s, periscopes were being used for naval navigation and in early submarines. During World War I, a perisocope sight was developed for rifles so soldiers could shoot over trench parapets without being exposed to sniper fire.
