The Aeroscope was built and patented in England in the period 1909 - 1911 by Polish inventor Kazimierz Prószyński. Aeroscope was the first successful hand - held operated film camera. The cameraman did not have to turn the crank to advance the film, as in all cameras of that time, so he could operate the camera with both hands, holding the camera and controlling the focus. This made it possible to film with the Aeroscope in difficult circumstances including from the air and for military purposes.
