The periscope was invented in the year 1854 by French inventor Hippolyte MariΓ©-Davy.
In trench warfare much use was made of devices which allowed an observer to safely see across no-mans land. The periscope was one such item.The periscope was made of wood and folded into halves so as to allow ease of carriage. When used in the trenches the folding periscope was often camouflaged with sacking. A periscope is also used for looking out of boats to see if an enemy ship is around.
