Le Stéréocycle Simplifié is a simplified version of the Stéréocycle. The camera was introduced in 1905 by Lucien Leroy. The simplified model uses common 6 x 13 cm glass plate negatives and eliminates the use of the sophisticated rotating system of the standard Stéréocycle. Although Leroy was not a fan of the 45 x 107 mm format, the simplified model was also available for the small format and was called Stéréocycle de Poche. The front panel with lenses can be adjusted vertically in height. This rising front movement supports the capture of higher objects without perspective distortion. The diaphragm adjusters of both lenses are connected by a bridge. Changing the setting adjusts the diaphragm of both lenses simultaneously.

Bazin, Leroy and Guérin
Charles Dessoudeix was a watchmaker. Dessoudeix’s company was founded in 1872, and located at 47, Rue du Rocher in Paris. In 1883, he helped Albert Londe with the development of a camera shutter. A year later, they presented their first shutter, branded Londe & Dessoudeix. Dessoudeix’s company was continued by Charles Bazin in 1891. Bazin partnered with Lucien Leroy, and together they introduced Le Stéréocycle, an innovative stereo camera that became very successful. Bazin left the company in 1899, and Leroy succeeded him. For more than 20 years, Leroy’s main focus was the manufacturing of the Stéréocycle and Stéréo-Panoramique stereo camera. Leroy partnered with Émile Guérin in 1916. Guérin took over the company in 1919 or 1920 and moved to 109, Rue du Bac in Paris. Guérin introduced new products to the company’s product line. New products continued to be introduced under the name Leroy. This was proof of Leroy’s strong reputation in France.
