He received a postgraduate degree at the Sorbonne six months after completing his baccalauréat. His many achievements include the creation of the French Institute of Speleology in 1962.

Main achievements
  • In his youth, he became interested in the space race and decided to find a way to contribute. Imagining situations faced by astronauts, he noticed that some of them could play in a deep cave. This motivated him to start his experiments.
  • The experience of time, two months cloistered in the abyss of Scarasson without time cues on a glacier, from July 1962.[1] He then organized several similar underground experiments for other speleologists. In 1972, Siffre went back underground for a six-month stay in a cave in Texas. He found that without time cues, several people including himself adjusted to a 48-hour rather than a 24-hour cycle.[2]
  • The notes of his experiments were used by NASA. Several astronauts reported experiences similar to those experienced in underground experiments such as loss of short-term memory to being isolated from external time references.
