[1] Robert Sénéchal (1892-1985) was a racing driver, an aviation pioneer and an industrialist.

Sénéchal was himself a celebrity in the automotive world, and his cycle cars were an immediate success.

[2] It was impossible to satisfy demand for the vehicles from the manufacturer's small premises at Courbevoie, and Sénéchal therefore negotiated a deal with Chenard & Walcker, who had no model of their own in the cyclecar class and from 1923 agreed to take on the manufacturing of the Sénéchal models.

[1][3] Voiturettes continued to be produced, powered by Chenard & Walcker engines, until 1929.

Engines were bought in from specialists such as Ruby, and, less frequently, Train or Chapuis-Dornier By the time of the 19th Paris Motor Show in October 1924, the Sénéchal range comprised two cyclecars.
