Pigeon photography is an
aerial photography technique invented in 1907 by the German
apothecary Julius Neubronner, who also used
pigeons to deliver medications. A
homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed
miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911
Paris Air Shows.
