Eugène Hénard and the End of the 19th Century

In 1910 the French architect and urban planner Eugène Hénard delivered a lecture at an RIBA conference on town planning. He was internationally famous for his Etudes sur les transformations de Paris, published between 1903 and 1909.[1] The conference was attended by architects and urban planners from all over the developed world, including the American architect and urban planner Daniel H. Burnham whose Plan for Chicago of 1909 was virtually a homage to Hénard.[2] It was publicly and enthusiastically supported by King George the Fifth. The proceedings were lavishly published after the conference. [3]

Eugène Hénard: proposal for Paris
from Transactions 1911
the drawing is inverted and rotated to show it in the same orientation as the photograph above.
Hénard’s proposals for Paris consisted mainly of road widening schemes. One was for an enormous roundabout in front of the Opéra (volume 7), part of a wider scheme which included a road through the middle of the Palais-Royal (volume 5) to facilitate access to Les Halles market. The Opéra and the Palais-Royal were 2 celebrated buildings and public spaces: the Opéra, designed by Charles Garnier in 1861-75, was regarded as one of the most, if not actually the most, famous building of the late 19th century in Paris, and the Palais-Royal, designed by Jacques Lemercier in 1633-39, was a former royal palace and important public open space. [4] Several important buildings would have to have been demolished on all sides of the Place de l'Opéra for the roundabout, including the celebrated Cafe de la Paix and part of the newly-built Grand Hôtel (which appear on the left in the photograph above).

The 13th Salon de l'Automobile was held in the Grand Palais, one of several Beaux-Arts iron-and-glass pavilions from the turn of the century in Paris. The Grand Palais was built for the Exposition Universelle [World’s Fair] of 1900, along with the Métro system. Manufacturers in France were the leading producers of luxury automobiles until the First World War, when they were overtaken by those in the United States, in particular Ford with the very popular and cheap Model T.
Recent and very comprehensive research papers have shown that increased personal mobility was a key social objective in Paris during the 20th century. There was at the time a true revolution in personal mobility, from cars and bicycles to women's clothes. The Métro opened in 1900 to provide transport for the Exposition Universelle [World’s Fair] of 1900. Automobiles were at the time restricted to the very wealthy and, judging from the photographs, traffic density was low. On the other hand, lorries, including the very advanced Berliet Type M launched in 1910, rapidly took over from horse-drawn vehicles, with their attendant problem of manure. It was thought at the time that there were no disadvantages - in particular air pollution - connected to motor vehicles. [5]
Hénard had studied, ironically, at the École des Beaux-Arts, the French School of Art and Architecture, rather than at is rival, the engineering-based École Polytechnique (which replaced the École des Ponts et Chaussées, or 'School of Bridges and Roads'). The École des Beaux-Arts was specifically oriented towards designing large public buildings, of which the Opéra was a flagship example. After graduating from the the École des Beaux-Arts, Hénard joined the Public Works Department of the City of Paris as an architect and began to gain recognition as a traffic engineer. [6]
Hénard presented his propsals for traffic management as scientific responses to mobility in the city, disregarding that they gave priority to one particular set of transport choices, particularly as the Métro was so successful. In London, the new buildings for Smithfield (Sir Horace Jones, 1866-67), the central wholesale meat market, were joined to the Underground and the basement contained large marshalling yards, thus mitigating a serious supply situation. Hénard's faith in technology had begun or had been nurtured during the 1889 Exposition Universelle [World’s Fair] in Paris, where he worked as an assistant on Victor Contamin's and Ferdinand Dutert's Palais des machines, at the time by far the largest vaulted iron structure in the world. One can see how architects, seduced by the engineering of structures, assumed technology could solve other, essentially political, problems. This leap in scope, from arranging circulation inside a building to managing circulation in cities, can be seen as a conceptual break in the role of the architect.

The boulevards in Paris are generally thought of as unique examples of cutting roads through urban fabric, but this is inaccurate. Firstly, many boulevards in Paris were actually along the lines of redundant fortifications, with a few linking boulevards to make a network. Secondly, Public Works Department in other cities were creating new roads at exactly the same time. In London, Regent Street (1811-25) had already been built, although as a royal development it does not belong with later, municipal, examples. Victoria Street, which cut through a slum in Pimlico, opened in 1851. Clerkenwell Road, 1874–78, and Rosebery Avenue, 1887-2, were cut through slums in Finsbury; Shaftesbury Avenue, 1886, through Soho. These Victorian streets are generally recognisable by the very poor architecture (Rosebery Avenue being an exception, as much of the work was undertaken under the LCC, which, in hindsight, marked a high point of architecture and urban design in London). After Henard's lecture, another road, Kingsway, opened in 1912, was cut through a notorious slum in Covent Garden and named in honour of King George the Fifth, who had so enthusiastically supported the RIBA conference. Burnham's Plan for Chicago was implemented partially and piecemeal, mainly as road widening, and he went on to be a consultant on the Macmillan Plan for Washinton D.C. generally considered a masterpiece of Beaux-Arts urban design. Both of these plans employed large diagonal boulevards as strategic design devices.

Paris is regarded by some political theorists as the 'Capital of the Nineteenth Century' or the 'Capital of Modernity'. Various academic theories (some far-fetched) have been put forward to explain the creation of Hausmann's boulevards, but their main purpose was to create a public realm to balance what was still a collection of intensely private spaces and social practices. The creation of the boulevards was the first time in urban planning in which urban spaces had been made deliberately for people to walk, even without any purpose, and cafes, shops, the first department stores and even opera houses supported and were reciprocally supported by, them. Circulation of other kinds - horses, goods, sewage etc. - was a complement. By contrast the roads proposed by Henard were through roads deliberately without connection to their surroundings. Streets have always supported the dual objectives of access to the buildings on either side and through traffic, but motorised traffic changed the nature of this balance dramatically. [7]

Henard’s proposal for the Place de l'Opéra signified a major break with the concept of 19th century urban space. Rather than being an isolated building, the Opéra, the Place de l'Opéra and the Avenue de l’Opéra were conceived as a unity. The evidence of contemporary photographs shows that in the early 20th century, when Hénard published his Etudes, these were still mainly pedestrian streets and pedestrians could enter the Opéra through the arcade. The grand entrance front was unashamedly a symbolic gesture, but it also had a very practical use as it was the main pedestrian entrance to the building. One can read a continuity of space from the Place and Avenue into the vestibule. The groundwork, therefore, for what is generally considered to be the 'Modernist' destruction of Paris actually had its foundations laid by an architect deeply embedded within the architectural establishment in the early 20th century.

It is ambiguous whether the entrance hall is an internal or external space. This is a peculiarity of buildings designed by architects from the École des Beaux-Arts, doubtless a result of the enormous areas devoted to internal circulation. Here it reinforces the connection to the street.

What did they wear?

A dress by Charles Frederick Worth, who initiated the system of haute couture in Paris in the second half of the nineteenth century. Worth was actually English and moved to Paris to develop his - eventually highly successful - business.

This dress is made of embroidered silk, in Worth's characteristic asymmetrical style which allowed for a long train. One can imagine the owner wearing this dress ascending the stair of the Opéra, its dramatic power matching that of the building, to attend a performance of Guiseppe Verdi's La Traviata, the life and death of a courtesan in Paris in the mid-19th century.

We can see with the benefit of hindsight that this style of dressing and the social conventions that went with it had largely disappeared by the first decade of the 20th century, although doubtless on the ground it appeared to continue. The Rational Dress Society was founded in 1881, with goals including lessening restrictions on personal mobility for women (intended to facilitate the use of the newly-invented bicycle) and promoting comfort.

This dress was worn by Paul Poiret's wife and muse Denise Poiret to the premiere of Igor Stravinsky's Sacre du Printemps [The Rite of Spring], (one of his 3 great ballets for Sergei Diaghilev's Ballets Russes and regarded as the first 'modern' music) for the opening of the Auguste Perret's Théâtre des Champs-Élysées on April 1, 1913. Contrary to popular histories, there is no evidence that this performance caused a riot. The Russian impresario Sergei Diaghilev, dancer Vaslav Nijinsky and composer Igor Stravinsky had financially viable and critically successful careers in Paris because it was receptive to the avant-garde. According to the Costume Institute, Denise Poiret's "svelte, gamine beauty... represented both the ideal of classical beauty and the paradigm of the modern woman."
The Théâtre des Champs-Élysées was the first theatre with a reinforced concrete frame, although it is not expressed as such along the street elevation. It is not clear what difference this makes to the building as a space for performance or spectacle, but the difference in appearance is striking: it is almost devoid of decoration. [8]

"The Life and Death of Urban Highways"

The uncritical acceptance of technology as a supposedly scientific solution to the problem of transport in cities went unchallenged throughout the developed world after WWII. It became politically expedient to develop urban highways in the United States to support mass suburbanisation, a result, in fact the purpose, of the Servicemen's Readjustment Act (1944, popularly known as the G.I. Bill). It was a short step from cutting roads through urban fabric to building elevated highways. These received substantial government suport under the Federal-Aid Highway Act of 1956 and were widely copied throughout the world. In London, trains to Smithfield market were ended, and elevated motorways built (under the GLC, which in hindsight marked a low point in urban design in London). It was thought at the time that there were no disadvantages connected to them. They became controversial when it became apparent that they caused immense blight to the areas they crossed, in particular areas of racially and socially disadvantaged citizens. Ironically, urban highways such as Robert Moses's Parkways in New York City of the 1920s and 1930s were regarded as the pinnacle of integrated urban highway design. [9]

This popular public space, previously a car park for the adjacent HMRC offices, is used for all kinds of events, including skating in the winter, temporary exhibitions and music shows. It is also the entrance to the Courtauld Gallery.
The reaction to urban highways began in the United States in the 1960s, when the activist Jane Jacobs (among others) successfully challenged Robert Moses’s Lower Manhattan Expressway, which would have destroyed Greenwich Village, at the time the bohemian quarter. Elevated urban highways began to be demolished, removing at a stroke the urban blight they had caused. Public antagonism to road widening in Paris began in earnest after the demolition of Les Halles market in 1971. There are now organisations dedicated to developing sustainable transport, and quality of life has become an important factor in urban design. In London, several important public spaces have been rehabilitated from parking lots, such as the courtyard of Somerset House (Sir William Chambers, 1775-78). It marks in a modest way the recovery of public space lost in Henard's proposal for a roundabout in front of the Opéra. [10]
