Eugène Hénard

Eugène Alfred Hénard (22 October 1849 – 19 February 1923) was a French architect and a highly influential urban planner. He was a pioneer of roundabouts, which were first introduced in Paris in 1907.

Hénard advocated several major urban projects in Paris, including great radial roads linking the center to a new ring road, and the expansion of the Place de l'Opéra. He was also a strong supporter of increased green space in cities. He proposed an innovative "stepped boulevard" arrangement, where buildings would be set at an angle to the line of the street, thus maximizing light into the apartments. His futuristic visions strongly influenced later architects, notably Le Corbusier. Provided by Wikipedia
