At its beginning, photography required innovators. Clever problem solvers envisioned the next innovations and then invented the solutions that would make those innovations possible.
One of these was Chicago’s John Carbutt, who invented—among other things—the celluloid film that made motion pictures possible. Carbutt, of course, also photographed Minnehaha Falls on several occasions in the 1860s. Another Minnehaha photographer who was a prominent photographic inventor and who worked at the turn of the last century was another Chicagoan: George Raymond Lawrence perfected aerial photography. It was quite a feat. Airplanes had not yet been invented.
