Le Caleb série DD est un appareil colonial, c'est à dire faisant l'objet d'une fabrication spéciale, afin de mieux résister aux conditions climatiques rencontrées sous les tropiques. Le Caleb série D propose déjà ce genre d'améliorations, mais le DD va encore plus loin. Globalement, la construction qui est la même pour les deux modèle est absolument superbe. On retrouve le bois de teck, l'aluminium et le soufflet gris. Mais sur le DD, le teck est extérieurement recouvert d'une feuille d'aluminium, de tel sorte que l'appareil lorsqu'il est replié ressemble à une valisette. Cela a deux avantage:. le premier est que l'aluminium s'oxyde très lentement en développant une fine couche d'alumine qui sert elle-même de protection pour l'aluminium en-dessous. Le second est que lors du transport à bord des paquebots desservants les colonies, la chambre bénéficie d'une protection anti-chocs.

D'un point de vue technique, il n'y a pas de différences entre les deux modèles qui évoluèrent parallèlement au cours de leur carrière pour suivre les progrès des obturateurs, des objectifs et des viseurs. Des changements esthétiques comme la forme de la poignée, la forme de l'abattant etc. furent apportés au série D et simultanément sur le série DD.

La forme de l'abattant est un élément de datation. Sur les plus anciens modèles (vers 1904 - 1905) les rebords sont rabattus, alors que sur les plus récents (c. 1909) l'abattant n'a pas de rebord. C'est le cas de notre exemplaire.

Si la série D était uniquement disponible en format 9 x 12 cm, la série DD était disponible en 9 x 12, 13 x 18 ou 18 x 24 (horizontal).

L'exemplaire présenté est équipé d’un Demaria Lapierre Anastigmat 6,8/13,5 cm série II et d'un obturateur Koïlos.

Ce modèle a également été commercialisé par Manufrance sous le nom de Folding modèle Colonial, en version D sous la référence 165 et 165A et en version DD uniquement en 13 x 18 sous la référence 167 et 167A.

The history of photography sometimes resembles a family tree.
The history of the Demaria-Lapierre-Mollier brand is a bit complicated. The obituary notice of Jules Demaria sheds some light on it. Two brothers, Jules (1866-1950) and Paul, joined forces in 1897 to manufacture cameras. This partnership between the brothers does not date back to 1848, as I have read here and there, since Jules was born only in 1866. The company they inherited from their family dates back to that year, and they later named it Demaria Frères (DMR).
In 1908, they absorbed the Lapierre company (DL).
In 1911, Jules separated from the partnership and founded the Jules Demaria company, registering the Jidé brand (phonetic for his initials).
In 1929/30, Demaria-Lapierre acquired the company of d'Etienne Mollier, and the company became Demaria-Lapierre-Mollier.

An article, perhaps better described as a sponsored feature, in the March 1931 issue of "L'Instantané" magazine recalls what the company was like at that time and delves into its history.



The Société Anonyme des Etablissements DEMARIA-LAPIERRE et MOLLIER was established in 1930 through the merger of the DEMARIA Frères, founded in 1848, LAPIERRE Frères et Cie, established in 1840, and MOLLIER et Cie, founded in 1923. Originally located at 169 Quai Valmy and 67 Rue des Archives, the company's headquarters are currently situated at 133 Boulevard Davout in Paris (20th arrondissement).

The company owns a factory in Lagny-sur-Marne, covering an area of approximately 7,000 square meters and employing over 120 workers.

The product range of Etablissements DEMARIA-LAPIERRE et MOLLIER includes various models of equipment and accessories for photography, projection, enlargement, and cinema:

1. Handheld cameras for plates and films of all formats.
2. Portable darkrooms for professional photographers.
3. Projectors for transparent and opaque views.
4. Enlargers with direct and reflected light.
5. Darkrooms and workshop equipment.
6. Laboratory accessories: trays, frame presses, calibrators, lanterns, retouching desks, printers, etc.
7. Educational cinema equipment.
8. Illuminated advertising devices.

In addition to the above-mentioned items, the modern organization of its workshops enables the DEMARIA-LAPIERRE et MOLLIER company to undertake significant custom work, including:

1. Aviation photographic equipment and materials.
2. Film rolls, sheet metal parts, and accessories for cinematography.
3. Magic lanterns and toy projectors.
4. Wooden boxes and cases for scientific and military equipment.
5. Optical and industrial photography equipment.

The history of the Société des Etablissements DEMARIA-LAPIERRE ET MOLLIER is marked by the merger of various companies:

- DEMARIA Frères, founded in Paris in 1858
- LAPIERRE Frères, founded in 1848
- MOLLIER et Cie, established in 1902
- Acquisition of other companies over time, including AUBERT, BOULANGER, MAUGENET, LEUZINGER et PINSON, BRUNET, LABORDE

The company initially focused on photographic manufacturing and closely followed the advancements in the field, from producing negatives, glassware, mirrors, accessories, and cameras to projection and enlargement equipment, up to contemporary technology.

From 1858 to 1908, the DEMARIA factories expanded significantly and were equipped with modern tools, located at Quai Jemmapes and Quai Valmy in Paris. Their manufacturing extended to:

- Handheld detective cameras
- Folding handheld cameras
- Tourist darkrooms in various formats
- Equipment for professionals
- Projectors and enlargers of all kinds
- Cinematography, filming, and projection
- Anastigmatic lenses and various other accessories for laboratories
- Special equipment for industrial photography

The DEMARIA house gained international recognition, supplying major ministries, government agencies, scientific institutions, observatories, educational institutions, and more. It received accolades at international exhibitions, including Paris 1900, Hanoi 1902, and Milan 1906, and won first prizes at Saint-Louis 1904, Liège 1905, Bucarest 1906, and London Saragossa 1908.

In 1908, it merged with the LAPIERRE company, which had established a lens condenser factory in Lagny-sur-Marne in 1900, primarily serving the English market. In 1913, it developed the first telephotography camera and dedicated its efforts to wartime production from 1914 to 1918, creating numerous models of aviation cameras, special photographic and projection equipment, and mobile laboratory equipment for the military.

In 1920, the Société D'OPTIQUE et de MECANIQUE de HAUTE PRECISION acquired DEMARIA-LAPIERRE, located at 125 Boulevard Davout in Paris, leading to further expansion and modernization of its factory and the development of new models. In 1930, it merged with the MOLLIER establishments, known for their metallic photographic equipment, precision general mechanics, and the manufacture of cinematographic equipment and projection materials.

Today, DEMARIA-LAPIERRE's product range encompasses a complete range of photography and projection equipment, accessories, some cinematographic models, and various specialized materials. Regaining its autonomy from the Société D'OPTIQUE et de MECANIQUE de HAUTE PRECISION, supported by extensive experience, conscientious technicians, cutting-edge tools, and a sprawling one-hectare factory, DEMARIA-LAPIERRE is poised for future growth as a significant industry player.
