The drawings in this patent for an early aerial photography system are relatively simple, and even seem a bit silly with a camera suspended from a kite string. But looks can be deceiving. Turns out, Mr. Eddy was famous for his photographic and meteorological experiments with kites. In fact, on May 30, 1895, Eddy took the first kite-based photograph in the Americas (seven years after the first ever kite-based photographs, taken by Arthur Batut). Mr. Eddy professionally as an accountant and journalist, but it's clear his passion was in science and technology...and inventing. Ironically, it's difficult to find the early Eddy kite photographs online.
