Hailed as a virtuoso writer and a “revolutionary whore,” Grisélidis Réal (1929–2005) chanced into prostitution at thirty-one after an upper-class upbringing in Switzerland. Serving clients from all walks of life, Réal applied the anarcho-Marxist dictum “from each according to his abilities, to each according to his needs” to her profession. Réal went on to become a militant champion of sexual freedom and prostitutes’ rights. She has described prostitution as “an art, and a humanist science.”
