I want to know the answer to the following question:
Who was Napoleon III's prefect of the Siene?
All the background I'm provided with is that "His successor, Napoleon III, and the newly appointed prefect of the Seine, Georges-Eugène Haussmann, launched a gigantic public works project to build wide new boulevards, a new opera house, a central market, new aqueducts, sewers, and parks, including the Bois de Boulogne and Bois de Vincennes.". Is that enough to answer the question?
Answer: yes
