Blétry frères

French patent agent Blétry frères was recorded as being at address boul. de Strasbourg, 2, Paris. This fraternal collaboration may have been a gradually formalized development. It would seem to refer to C. Blétry and E. Blétry prior to their father's death in 1901. See Blétry for what clarification we have at present. See also Blétry aîné‎.

This street address, on boulevard de Strasbourg, to some extent, any other addresses, to a greater extent, all on boulevard de Strasbourg, are starting to stand out as an activity hub.

We have them identified as "Ingénieurs Civils".
