Lebon, Philippe. Thermolampes ou poêles qui chauffent; éclairent avec économie, et offrent, avec plusierus produits précieux, une force motrice applicable à toutes espèce de machines; inventés par Philippe Lebon, ingénieur des Ponts et Chaussées. 1801.

Philippe le Bon is the inventor of gas lighting and combustion engine, for which he placed patents in 1799 and 1801
In this rare booklet he explains these new concepts and he proposes to carry out public demonstrations of his inventions and launched a subscription in order to industrialize them.
The Hôtel Seigneley was equiped two month later with his Thermolamp for Gas lightling and heating.
Lebon died prematurely in 1804 has not had the time to develop his combustion engine and we have to wait more than 50 years until Jean Joseph Etienne Lenoir realize the first combustion engine.
