He started with some pretty dangerous explorations, where he dived naked into a
siphon, only with water tight packed candle and matches.
Later he writes in several books about this, and warns not to copy this
dangerous lapse.
Later he learned the techniques of caving from
E. A. Martel.
Martel, the founder of speleology wrote the foreword to his first book.
Unlike Martel, he was not a speleologist by profession.
He studied and worked as a notary public.
But he also studied prehistory at the Muséum d'Histoire Naturelle de
Toulouse.
This knowledge was very important for his later prehistoric discoveries.

Here are the probably most important ones.
Many of this books were translated into other languages.
