After starting a military career, which he had to abandon following the adoption of the law of June 4, 1886, prohibiting members of families that had reigned over France from serving in the army, he turned to geography, geology, speleology, and ethnology, and later to botany. He created a very important herbarium. He was more broadly a scientific collector.
