Buenas tardes jellby,
Here a quote from Wikipedia (translated in english from french) : "His scientific works are less known (research on color photography and a patent for freeze-dried coffee, and very thorough work on the synthesis of rubber)."
I was curious about that because you are a scientific and I like things about coffee and photography! I have had a look to Gallica.fr and I found nothing. Anyway, it's not very important and his scientific works have probably not been "révolutionnaires".
