H. Labitte 26 rue de Ménilmontant, Paris
There are two Labitte firms: Hyppolite, and Eugène, both specialists in light engines.
One of these firms acquired Landru in 1900.
Eugène Labitte had sold his plans and patents to Dalifol. (Bourdache p44)
It is believed a Labitte engine was used in one of the first Werner motorcycles.
