Raymond d'Equevilley-Montjustin

Raymond d'Equevilley-Montjustin, the Marquis d'Equevilley (also spelled "Ecquevilly") was an aero inventor who developed a big wheel-shaped multiplane in 1908.[1][2]

An espacenet search returns 69 patents granted internationally to d'Equevilley, almost all of them dealing with submarines. These include technology related to steam propulsion. They are filed in Spain, England, France, Germany, the United States, and Denmark.

His name breaks the cargo search – because of the apostrophe? But see
