The problem: her marriage of convenience (in 1845, the same year as the foundation of SPA) was to Claude Bernard (1813-78), who would become the father of experimental medecine and whose ideas would influence Émile Zola, who wrote Le Roman expériemental in 1878. And not only did Fanny's father's money go towards Bernard's experiments on the vivisection of animals, particularly dogs, but he carried out some of his experiments in the family home. Fanny tried her best to counter this by rescuing stray dogs. The very strained marriage came to an end in 1868, and they were officially separated the following year.
Poor before his marriage, Bernard originally went to Lyon to work in a chemist's and had the idea that his vocation lay in writing. At twenty he'd written a play, Arthur de Bretagne, although it wasn't published until 1887, some years after his death. It contains a truly awful and heavily biased Preface by a certain Georges Barral, who accuses Fanny and her daughters of deserting Bernard. Needless to say, the above shows that their attempts to destroy the book were fruitless, although the latest publication appears to omit the Preface. No, I haven't read the play, and certainly never will.
It would be interesting to see what the Musée Claude Bernard in his native town of Saint-Julien-en-Beaujolais says about Fanny Martin, who has become a recent martyr to the animal rights cause.
