French patent agent Dominique-Antoine Casalonga, a.k.a. D.–A. Casalonga was recorded as being at Paris, rue des Halles, 15. I believe was an assignee of Alphonse Tellier et Cie.

Beginning 1878, Casalonga published La Chronique industrielle, describing industrial developments, with a focus on new patents and industrial property law.[1] He was an engineer with a specialty in thermodynamics.

Dominique-Antoine Casalonga died in 1903 and the office was taken over by his son Doumé Casalonga.[2]

The name Dom. Casalonga appears on patents after 1903.[3]

Sometimes the name Casalonga appears alone (and sometimes this is because our source for the patent is Bulletin des lois or a similar abbreviated format).
