Lebaudy Frères was a French sugar producer based in Moisson, France. In addition to sugar, they also made a series of semi-rigid airships in the early years of the twentieth century, some of which saw service with several European armies.
Operation
editPaul and Pierre Lebaudy were the owners of a sugar refinery who, with the assistance of their engineer Henri Julliot as designer, built semi-rigid airships which saw service with the French army, the Russian army and the Austrian army.[1]
They constructed an airship hangar at Moisson, near the River Seine downstream from Paris[2] and were instrumental in the development of airships in the first decade of the twentieth century.
Their semi-rigid airships were considered useful for military purposes and several were ordered by the French War Ministry.[3]
