Auguste-Adolphe Bertsch

• Name — Auguste Adolphe Bertsch • Born — 1813 • Birthplace — France • Died — 1871 • Place of death — Paris, France • Occupation — Photographer, optical instrument maker • Known for — Microphotography; photographic process innovation; Chambre Automatique • Notable Works — Études d’Histoire Naturelle au Microscope (1857) • Organizations — Société Française de Photographie

Auguste Adolphe Bertsch was born in France in 1813. Little is known about his early life or formal education, but he trained in optics and became involved in photographic experimentation during the rapid development of photography in the mid-19th century.

Around 1860, Bertsch designed a miniature camera known as the Chambre Automatique. Using wet collodion plates, the camera was notable for its compact size and fixed-focus lens, making it one of the earliest examples of a sub-miniature photographic camera.

Bertsch retired from active photographic work in 1863. He died in 1871 during the events of the Paris Commune, a period of civil unrest following the Franco-Prussian War.

By the early 1850s, Bertsch was actively engaged in photographic research, particularly in the application of photography to microscopic subjects. He worked extensively with the wet collodion process and, in 1851, introduced improvements that increased its sensitivity, enabling shorter exposure times. In the same period, Bertsch developed a disc-shutter mechanism and published technical notes on the use of rapid collodion. His work contributed to the refinement of photographic equipment at a time when the medium was transitioning from experimental practice to broader scientific and artistic use. Bertsch was also an early practitioner of photomicrography, producing photographs of insects, crystalline structures, and other natural subjects viewed through the microscope. These images are among the earliest examples of photography applied systematically to microscopic scientific observation.

In 1854, Bertsch was among the founding members of the Société Française de Photographie (SFP), one of the earliest photographic societies in the world. He later served on its governing board from 1858 until 1870, reflecting his standing within the French photographic community.
