**EDIT**

He has received the Légion d'Honneur:

http://www2.culture.gouv.fr/public/mistral/leonore_fr?ACTION=RETROUVER&FIELD_1=NOM&VALUE_1=VOGT&NUMBER=17&GRP=0&REQ=%28%28VOGT%29%20%3aNOM%20%29&USRNAME=nobody&USRPWD=4%24%2534P&SPEC=9&SYN=1&IMLY=&MAX1=1&MAX2=1&MAX3=100&DOM=All

This says that he is born the 24th of January 1864 in Sermaize (Marne).

His "acte de naissance" says that his correct name is "Henry Gustave". He is the son of Jacques Georges Vogt and Charlotte Gabrielle Cavelier.

And the last document in the Légion d'Honneur file contains a short biography!
