Submarines adopted periscopes early. Captain Arthur Krebs adapted two on the experimental French submarine  in 1888 and 1889. The Spanish inventor Isaac Peral equipped his submarine  (developed in 1886 but launched on September 8, 1888) with a fixed, non-retractable periscope that used a combination of prisms to relay the image to the submariner. (Peral also developed a primitive gyroscope for submarine navigation and pioneered the ability to fire live torpedoes while submerged.)
