Édouard-Jean Bigourdan
Edouard Jean Bigourdan was an aero inventor and self-described engineer and gentleman who filed patents from Maisse, département Seine-et-Oise, France. On two patents we see "Edmond", instead of "Edouard". Both are patenting in collaboration with Alexis Beurrier. Are they the same person or not? Assuming the same person for now.
We have some growing data on location changes on the part of Édouard-Jean Bigourdan, as such, filing from Montguyon, département Charente-Inférieure, France.[1] We have him later filing from département Seine-Inférieure, France.[2] We have Edmond Bigourdan, as such, filing from within Seine-et-Oise, in collaboration with Alexis Beurrier, filing from within Charente-Inférieure.[3]
These are odd relations. It is not impossible that Alexis Beurrier worked collaboratively with two likely related Bigourdans, sharing the location data Montguyon, Charente-Inférieure with one of them. We are still leaning to the idea that we are dealing with one inventor with the surname Bigourdan, as odd as the changes in name for may be, and as odd as some of location moves, relative to other collaborators, may also be.
We having Jean Edouard Bigourdan, as such, filing from Maisse, département Seine-et-Oise, France, in collaboration with Alexis Beurrier, filing from Thaims, near Cozes, département Charente-Inférieure, France.[4]
We have Edmond Bigourdan, as such, filing in simultaneous collaboration with Alexis Beurrier and Louis Lacoin.[5]
