Lachambre supplied balloons to both the US Signal Corps and the ill-fated arctic mission of S. A. Andrée in 1897. He also worked with the Brazilian aviation pioneer Alberto Santos-Dumont, taking him for his first balloon ascent and going on to construct his first balloon in 1898 and later the envelopes for his dirigibles.
Together with his nephew Alexis Machuron Lachambre wrote a book about Andrée's expedition, ''Au pôle nord en ballon'' (Imprimerie Nilsson, 1897, 250 pages), which was quickly translated into Swedish, English, French, German, Italian, Dutch and Polish.
