He was president of the Institut Métapsychique International, and edited and wrote theoretical and experimental reports for its journal.

He obtained a degree in chemical engineering in 1903 from the École Nationale Supérieure de Chimie.

He patented several processes related to the synthetic production of precious stones, and invented special screens for movie projection.

Warcollier's main parapsychology studies involved experiments using a telepathy design in which one or more "agents" observed a target image while one or more "percipients" attempted to "blindly" reproduce it.
