Nicoló Degiorgis (ed.), Audrey Solomon (ed.): Julius G. Neubronner – Pigeon Photographer (Rorhof, 2017)

Julius G. Neubronner, born 1851 in Kronberg im Taunus as the son of a pharmacist, cultivated a curious passion for photography. In 1907 he patented the design of a camera which could be attached to pigeons and would automatically take pictures during their flight in order to track their journey.
