I’ve recently discovered Albert Londres (1884-1932), a globe-trotting French journalist who seems a bit like a real-world, earlier, more principled Tintin:
Misery is like any other State. Only those who live in it know it. Others don’t even think about it. And when sometimes they do talk about it, they do so as of a country they’ve never seen, that is to say that they only talk a lot of nonsense.
This is from Les Chemins de Buenos Aires (the extract’s translation is mine), a book-length report on the apparently flourishing sex trafficking at the time (1927) between France and Argentina. In this often quite funny first-person account, Londres follows French pimps from Paris to Buenos Aires, tells of how they seduce or trick women into following them, how they cross the ocean and avoid the authorities, how they set them up in Argentina. It’s quite extraordinary to be transported to such a time and place (and milieu), to hear early 20th century pimps in their own words.
Other works of his that I plan on reading include Au bagne (on the French penal colony in Guyana), Chez les fous (an investigation of mistreatments in psychiatric institutions) as well as works on different subjects set in colonial Africa.
His books are translated in English, but I’m not sure how easily one could get his hands on one. But I’d recommend trying! Or if by any chance you read French, a good few of his works are available for free (Public Domain) on Wikisource.
