French patent agent Blétry, based on dates active, probably refers to Constant Blétry, who founded l'Office Blétry in 1866 after working with Armengaud. His sons (Blétry frères) Camille (C. Blétry) and Edmond (E. Blétry) took over the firm after his death in 1901.[1] See Blétry aîné for a wealth of material pertaining to the 1890s, whereas the other above-mentioned Blétry-named pages pertain to material drawn from the first two decades of the Twentieth Century.
Much later Blétry activity seems revolve around a boulevard de Strasbourg activity hub.
We have simple Blétry located at Paris (6, rue des Filles-du-Calvaire, Seine).[2]
A. Blétry has also entered our data.[3]
