Emile Gos originated in a family of artists. His father Albert was a painter, while his brothers Charles and Francois devoted themselves in literature and painting respectively. Emile began his apprenticeship in photography at Montreaux in 1904. Subsequently he left his native land to visit Munich and Paris, and worked as Operator Assistant for Rentlinger in London. Upon his return in Switzerland he was based at Clarens and later, in 1913, at Lausanne. Having been assigned by the Ministry of Foreign Affairs of Switzerland to organize presentations on Italy, France and Belgium , he created a series of slides for projections out of his own negatives. Following the example of his parents he passionately dedicated himself to taking photographs of the mountains. He photographed the mountain peaks from various angles, took aerophotographs and demonstrated an interest for the activities of the people living in the Alps. He was equally active in the cinema. The Emile Gos Bequest comprises ten large albums with approximately 3,000 negatives and positive films, which the photographer sold to the Canton's Archive, and which the Gos family continues to date to enrich with donations.
