On this day in 1907 Guiseppe Pino was granted the patent for HYDROSCOPE. U.S. Patent No. 849,570.
This invention has for its object a hydroscope for exploring and photographing the bottom of the sea from the surface and recovering submerged objects. It is known that telescopes already exist for, exploring the bottom of the sea; but such apparatus as heretofore constructed are not capable of attaining the objects of this invention – that is to say, of obtaining perfect images lying on the bottom of the sea.
