He published hundreds of articles for technical and scientific journals such as L'Aérophile, La Nature, la Revue Scientifique, La Science illustrée, and L'électricité.

During the siege of Paris in the Franco-Prussian War, he escaped from the city in a balloon and went to London.
His brothers, Arthur (1830–1914) and Ulrich (1833–1911), were political journalists.
