Levavasseur project

The Levavasseur project was an early project for a tank designed in 1903 by the French Captain Léon René Levavasseur (1860-1942) of the 6th Artillery Battalion, described as a "self propelled cannon project" (French: Projet de canon autopropulseur). It is considered as the first description, made by a soldier, of what would come to be known as the tank. Levavasseur was a graduate of Ecole Polytechnique, of the promotion of 1881. According to Armoured Fighting Vehicles of the World:

A project for a vehicle which had all the characteristics later thought desirable in a tank was put forward to the French War Ministry as early as 1903. Devised by a Captain Levavasseur of the 6th Artillery Battalion, who called it a "canon autopropulseur", the vehicle was envisaged as carrying a 75mm gun mounted in a box-like steel caisson which ran on crawler tracks, or "roues articulées" as Levavasseur called them. Powered by an 80hp petrol engine, the Levavasseur machine would have had a crew of three, storage for ammunition, and a cross-country ability.
