Henri Salmson, a manufacturer of water pumps, was engaged by Georges Marius Henri-Georges Canton and Pierre Unné, a pair of Swiss engineers, to produce engines to their design. First run in 1908, their initial efforts were on barrel engines, but these failed to meet expectations due to low reliability and high fuel consumption caused by internal friction.
 
A new design, a 7-cylinder water-cooled radial design, was then developed by Canton and Unné. This was expanded to produce 9-cylinder models, and also two-row 14-cylinder and 18-cylinder engines. By 1912 the Salmson A9 was producing around 120 brake horsepower; while competitive with rival designs from French companies, Salmson, Canton and Unné decided to develop more powerful engines as their rivals were concentrating on engines of lower power.
 
The engines were produced at Société des Moteurs Salmson's factory at Billancourt, which was expanded during the First World War, and a second factory was opened at Villeurbanne. The Salmson-(Canton-Unne) series of water-cooled engines were also built by licensees in Russia and in Great Britain at the Dudbridge Iron Works Limited at Stroud in Gloucestershire between 1914 and 1918.

Salmson produced the series from 1908 until 1920.
