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. Eugène Hénard was born in 1849. His father, Antoine-Julien Hénard, was a professor of architecture at the École des Beaux-Arts, known as the "architect of the 12th" for his work in the 12th arrondissement of Paris. Eugène Hénard studied architecture under his father at the École des Beaux-Arts. He proved to be an able student and won several prizes. Eugène Hénard did not win the Grand Prix de Rome, but qualified as an architect in 1880. In 1882 Hénard obtained a position with the Travaux de Paris, the office of public works, remaining with this department for his working life. At first his main responsibility was the design of school buildings. During the planning for the Exposition Universelle (1889) Hénard proposed installing an innovative continuous train system to move visitors around, reducing fatigue and improving flow. The continuous train, or moving sidewalk, would have been powered by electricity. His design had a series of 320 wagons forming a continuous loop with a length of . They would run through the exposition on rails in a trench. Each wagon would be covered with a wooden floor at ground level, and would move relatively slowly. Young and agile passengers could jump on or off at any point. The train would frequently come to a halt for the convenience of women, children and older passengers.
