Who was Claude-Marius Vaïsse, the Haussmann of Lyon?

The son of bourgeois Marseilles, Claude-Marius Vaïsse was for 10 years the prefect of Lyon. Appointed by Napoleon III in 1853, he completely transformed the city. Le Haussmann Lyonnais rethought the Presqu'île, imagined the streets of the Re and President Edouard-Herriot... But also created the Parc de la Tête d'Or. If Lyon is now a UNESCO World Heritage Site, it is largely thanks to him.
