Pierre Molinier was the son of a house painter and decorator specializing in marble and wood imitation; his mother a dressmaker, and his aunt an ironer. Molinier's school years were spent with the Brothers of the Agen "Ecoles chrétiennes", although he pretended he had been educated by the Jesuits. At the age of 13, he began working with his father as an apprentice painter and took evening courses at the Agen Municipal School of Drawing. Having been in love with his younger sister for a long time, in 1918, he took a photograph of her on her deathbed: later he said that, on that occasion, he caressed her legs and ejaculated on the First Communion dress she was wearing. Fantasm, pure fabrication or reality ?
Anyway, it was the starting point of his quest for an androgynous identity, which would be a recurring theme throughout his life and work.
