Louis-Marius-Alexandre Marmonier was an aero inventor from Lyon mostly working in the area of gyroscopic stabilizers. He continued to file patents in this area into the 1930s, during which period he also designed a full airplane.

One French patent gives us the full name Louis-Marius-Alexandre Marmonier, along with the specific location rue Servient, 37, Lyon, département Rhône, France.[1] That patent, as is often the case, offered good address data on the inventor because no patent agent was involved in the filing. All the other French filings here corroborate the basic data département Rhône, France.

American data also gives the address rue Servient, 37, Lyon, France.[2]

British data gives the address rue Servient, 37, Lyon, France, as well, and identifies the inventor as an Engineer.[3]
