Georges-Eugène Haussmann (French: [ʒɔʁʒøʒɛn osman]; 27 March 1809 – 11 January 1891), known as Baron Haussmann ([baʁɔ̃ osman]), was a French official who supervised a radical urban renewal programme of new boulevards, parks, and public works in Paris, referred to as Haussmann's renovation of Paris, aimed at introducing grandeur in the city. First a prefect in Var (1849–1850), Yonne (1850–1851), and Gironde (1851–1853), his skills as an administrator led to his appointment in Paris by Emperor Napoleon III in 1853.
The signature architectural landmark of his works was the Paris Opera, the largest theatre in the world, designed by Charles Garnier, crowning the centre of Napoleon III's new Paris. Haussmann completely rebuilt Paris above and below ground; on his own estimation by 1870 one in five streets in central Paris were his creation, while revamped sewers now ran alongside miles of pipes to distribute gas for thousands of new streetlights. With his right-hand Adolphe Alphand and at the Emperor's direction, a plan was laid out for four major parks at the cardinal points of the compass around the city: the Bois de Boulogne to the west, Bois de Vincennes to the east, Parc des Buttes Chaumont to the north, and Parc Montsouris to the south. The major parks and their smaller counterparts in the city were an immediate success with all classes of Parisians.
