In 1907, German apothecary Julius Neubronner invented an aerial photography technique known as pigeon photography. By affixing a lightweight time-delayed miniature camera to an aluminium breast harness, Neubronner attached his design to homing pigeons who would then be able to capture aerial photographs during their flight.
In 1903, Julius Neubronner, an apothecary in the German town of Kronberg near Frankfurt, resumed a practice begun by his father half a century earlier and received prescriptions from a sanatorium in nearby Falkenstein via pigeon post. He delivered urgent medications up to 75 grams (2.6 oz) by the same method, and positioned some of his pigeons with his wholesaler in Frankfurt to profit from faster deliveries himself.
When one of his pigeons lost its orientation in fog and mysteriously arrived, well-fed, four weeks late, Neubronner was inspired with the playful idea of equipping his pigeons with automatic cameras to trace their paths.
