André-Julien Mahoudeau
André-Julien Mahoudeau, sometimes listed as “André-Julien Mahoudeau dit de Villethiou”, was an aero inventor addressed at rue Littré, 17, Paris, département Seine, France.[1]
Atypically, British patent data gives no occupation for this inventor, and gives the name form “André-Julien Mahoudeau de Villethiou”.[2] This may suggest a stretched claim of nobility, so whereas some French patents have him as called “de Villethiou” the British patent uses simply “André-Julien Mahoudeau de Villethiou”.
During the same general time period during which these aero-patents were filed André-Julien Mahoudeau was also engaged in work with the hands or indicators time pieces, filing related patents in France, Great Britain and Spain, and possibly elsewhere.
Beyond this inventor, the surname “Mahoudeau” comes up in our data only in connexion with Publication 1218, 1890, Ballon à compartiments Mahoudeau. Presently, we are unaware of any relation.
