Aron, the maternal uncle of the historian Henri Hauser,[1] was born in Besançon to a middle-class Jewish family of republican sympathies.

[2][3] On the suggestion of Ernest Picard, France's Interior Minister in the early days of the French Third Republic, he was appointed director of the Journal officiel de la République française in 1876.

[3][4] Afterwards, he returned to the Journal des Débats as its literature and theatre critic, but his deteriorating health eventually forced him to retire.

In La France juive in which Drumont attacked the role of Jews in French society and argued for their exclusion, he accused Aron of firing him from a minor position at the Journal officiel because he was a Christian.

His funeral was conducted by the Chief Rabbi of Paris, Zadoc Kahn, with the eulogy given by Tony Baugier, the director of the Journal officiel at the time.
