Earlier he had been titular bishop of Rhosus[2] appointed to the diocese of Nancy and Toul.

A major figure in Napoleon III's Liberal Empire period he was renowned for his energy, e.g. in publishing and in the restoration of churches in his diocese of Bordeaux (including Bazas though without that title).

Eleven volumes of his pastoral instructions, sermons and writings were posthumously published.
