Born in Burgundy to schoolteacher parents, Jean Perdrizet spent his single life with his mother, father, sister, and nephew. After graduating from high school, he earned a technical assistant diploma in 1931. Placed on leave due to health reasons, he worked intermittently for EDF (Électricité de France) from 1944 to 1949, and then oversaw the construction of the Bollène bridge.

Around 1955, he established himself as an "inventor," creating prototypes and plans for machines designed to communicate with the dead, ghosts, and extraterrestrials.

Following his father's death, he built a spirit table to contact him and organized séances with his neighbors. He invented "T-language" or "Sidereal Esperanto," which he claimed to "speak fluently."

His highly complex plans blend formulas, sketches (sometimes colored), technical specifications, theoretical explanations, and religious or metaphysical considerations. Seeking to publicize his innovations, he sent his plans to scientific organizations likely to be interested, including NASA, science faculties, the Vatican, UNESCO, and the Southern Academy of Sciences, hoping to receive a Nobel Prize… to no avail. Nevertheless, several renowned scientists took an interest in his work.

His works are featured in the most prestigious private collections, as well as in the collections of the Centre Pompidou, the Collection de l'Art Brut, and the LaM.
