In 1951 Maurer developed a small, fast-cycling aerial camera and spent much of the next four years working on aerial photography. In 1955 Maurer left J.A. Maurer, Inc., and the following year established J.M. Developments. This company was intended to specialize in motion pictures, but much of the work continued his aerial photography research, including a camera with an extremely fast shutter speed. The high-speed shutter allowed low-altitude and supersonic planes to photograph continuously. This shutter was part of a camera used in reconnaissance missions over Cuba during the missile crisis of 1962. Maurer developed a 70mm camera used in the Gemini XI mission in 1966 and on the first moon landing.
