Letourneur & Marchand, located in the prosperous Paris suburb Neuilly-sur-Seine, was a car body manufacturing business which became one of the last French coachbuilders.
Since 1900, Letourneur had worked as a designer for the established carriage manufacturer Binder Carrossier in Neuilly-sur-Seine, which Marchand also joined shortly afterwards after completing his training as a wheelwright.
In 1924 the company created a subsidiary called Autobineau to specialise in sedan and limousine car bodies produced in greater volumes and in a slightly more standardised format than was associated with the upmarket coach builders.
Marcel Letourneur often created aerodynamically designed bodies that had a low beltline and did without a central vehicle pillar in order to make the roof structure appear lighter.
This included, among other things, France's economic weakness in the early post-war years, which meant that demand for exclusive luxury vehicles was very limited.
Letourneur et Marchand also found themselves one of numerous auto-businesses far too small to feature significantly in the government's vision for an export led French auto-industry dominated by a handful of large manufacturers.
