Julius Gustav Neubronner (8 February 1852 – 17 April 1932) was a German apothecary, inventor, company founder, and a pioneer of amateur photography and film.

Neubronner was court apothecary to Kaiserin Friedrich, invented the pigeon photographer method for aerial photography, was one of the first film amateurs in Germany, and founded a factory for adhesive tapes.

His godfather Julius Löwe operated a chemical laboratory in Frankfurt, and from 1864 the now twelve-year-old boy attended the Gymnasium in that city.

[9] Wilhelm Neubronner had used pigeon post for fast delivery of prescriptions, but had stopped the practice after a few years, when the neighbouring villages received their own pharmacies.

By pigeon post he obtained urgent chemicals up to 75 grams (2.6 oz) from his wholesaler in Frankfurt and delivered urgent medication to the sanatorium in Falkenstein (Königstein im Taunus)[5] The notable sanatorium, founded in 1876 by Peter Dettweiler, was replaced by a recreation home for officers between 1907 und 1909.

[11][12] The cumbersome process of gluing glass photographs for laterna magica presentations inspired him to invent a form of adhesive paper tape, which he patented.

[15][16][17] Like his father, Julius Neubronner was a friend and sponsor of a Kronberg-based group of notable painters known as Kronberger Malerkolonie, whose museum is now located on the first floor of his house.

[22] Spectators in Dresden could watch the arrival of the camera-equipped carrier pigeons, and the photos were immediately developed and turned into postcards which could be purchased.

[4] The invention was tried out for military air surveillance in the First World War and later, but apart from honourable mentions in encyclopedias (Meyers Konversations-Lexikon, Brockhaus Enzyklopädie) it only caused him expenses.

In 1957 he received the Federal Cross of Merit (1st class), in 1966 he made the staff share the company's profits, and he was active in an industry association.
