The Exposition des produits de l'industrie française (; ) was a public event organized in Paris, France, from 1798 to 1849. The purpose was "to offer a panorama of the productions of the various branches of industry with a view to emulation".

Background

The Paris industrial expositions between 1798 and 1849 can trace their origins to the fairs that were held in several cities of Europe in the Middle Ages. After the start of the French Revolution of 1789–98 the authorities staged a series of festivals in Paris, starting with the Festival of the Federation on 14 July 1790 and followed by events such as the Festival of Law (1792), Festival of Reason (1793), Festival of the Supreme Being (1794), and Festival of the Foundation of the Republic (1796). These celebrations of the new republic helped to unite the people and win acceptance of the new order.

The Directory launched the first exposition at a time when France was engaged in external wars and was still in upheaval from the revolution. The idea of an industrial exposition emerged from discussions led by the Minister of the Interior François de Neufchâteau over how to celebrate the anniversary of the Republic's foundation. The Directory approved and on 9 Fructidor, Year VI (26 August 1798), François de Neufchâteau notified the government officials that an Exposition of the products of French industry would be held along with the 1 Vendémiaire VII (22 September 1798) anniversary celebration.

French First Republic: 1st exposition (1798)

The first exposition was held at the Champ de Mars. The architect Jean-François Chalgrin, who later designed the Arc de Triomphe, undertook the hasty construction of a large circle of porticos surrounding a Temple of Industry. The temple would hold the objects of industries that the jury had selected. The official exposition took place during the five last days of the year VI (19–21 September 1798). The exposition opened on 19 September 1798 with a parade led by trumpeters and cavalry, with musicians, soldiers, heralds, manufacturers, the jury and politicians. There were 110 exclusively French exhibitors. Due to the short notice, there were relatively few exhibitors, all from Paris or the neighboring departments. There were further festivities and speeches on the fifth day, the last official day of the exposition. The exposition remained open until 10 Vendémiaire Year VII (1 October 1798).

Exhibits included an instrument for cataract operations, paintings made from the plumes of exotic birds, a machine for extracting logs from rivers and a device that demonstrated the new metric system of meters, grams and liters. The jury was told to favour products that were comparable to those of British industry. Twelve exhibitors were given honorable distinctions. Thirteen received honourable mentions. Honorable distinctions included:

Abraham-Louis Breguet: a clock with free escapement. Étienne Lenoir (1744–1832): a precision balance. Pierre and Firmin Didot and Louis Etienne Herhan: an edition of Virgil. Jean-François Clouet: iron transformed into steel. Nicolas-Jacques Conté: crayons of various colors.

Napoleonic era

The exhibitions that followed the first exposition were always strictly for French products, and were increasingly successful.

2nd exposition (1801)

The Minister of the Interior, Jean-Antoine Chaptal, sent his recommendation for another industrial exposition to the three consuls on 22 Brumaire Year IX (13 November 1800). After the continental peace seemed assured, on 13 Ventôse Year IX (4 March 1801) the first consul (Napoleon) ordered another exposition for the 5 last days of year IX (1801). This exhibition was much more brilliant than the first, with more competitors and higher quality exhibits. The second exhibition was organized in the square courtyard of the Louvre Palace. It was held from September 19–25, 1801.

There were 220 exhibitors. 19 gold medals were awarded in total, including seven who had received honorable distinctions in Year VI, and 12 new exhibitors. The three consuls visited the exposition on the last complementary day (22 September 1801, and distributed 12 gold medals to manufacturers including Jacob Frères. The Jacobs shared the medal for furniture with Lignereux. The revolutionary Jacquard loom, driven by punch cards, received a bronze medal. The jury's report noted that it "replaces a worker in the weaving of brocades". It took several years before it was realized that rather than replacing weavers, the loom made higher volumes of sales possible and employed many more workers.

3rd exposition (1802)

In the year X (1802) the exposition lasted 7 days, with 540 exhibitors. It took place from September 18–24 in the courtyard of the Louvre. There were 540 exhibitors. The exhibitors came from 63 departments, of which 12 would be separated from France in 1815. Chaptal, Minister of the Interior, was not interested in brilliantly executed work or in commonplace manufactures, but valued products for their utility, quantity and price. He saw the same merit in coarse pottery, if it was good and cheap, as the most elegant porcelain. 38 gold medals were awarded. There were 53 silver medals and 60 bronze medals. Martin-Eloy Lignereux was awarded the gold medal for cabinet-making.

4th exposition (1806)

After the Year X exposition the government decided that more time was needed between the expositions to allow for advances in manufacturing to mature, and put off the next exposition until 1806. In the interim the Société d'encouragement pour l'industrie nationale, founded in 1801, continued to give prizes for many branches of industry. The Emperor Napoleon decreed the 1806 exposition on 15 February 1806 after his return from the Austerlitz campaign, and the event was in part to celebrate his victories by exhibiting the fruits of peace.

The 1806 exposition lasted 24 days, with 1,422 exhibitors. It was held from September 25 to October 19 on the Esplanade des Invalides, arranged by Chaptal's successor as Minister of the Interior, Jean-Baptiste de Nompère de Champagny. Awards included 54 gold medals, 97 silver medals and 80 bronze medals. Nicolas Appert presented a selection of bottled fruits and vegetables from his manufacture but did not win any reward. Jean-Baptiste Launay presented the first model for a dome for the Paris wheat market and two cast iron bridges for the capital.

Napoleon had decreed that industrial expositions would take place every three years, with the next due to open on 1 May 1809, but military and political difficulties prevented further expositions during the remainder of the First French Empire.

Bourbon restoration

The government of King Louis XVIII, after appointing Élie, duc Decazes to the post of Minister of the Interior, decided to revive the expositions of products of French industry. A royal ordinance of 13 January 1819 decreed a series of expositions at intervals of no more than four years, with the first to be held in 1819 and the second in 1821. As with previous expositions, the products had to be strictly French. The prefect of each department would name a jury which would select well-made and useful manufactured products for exhibition, preferably choosing products distinctive to the region. They should not reject coarse products as long as they were useful.

5th exposition (1819)

The 19 member jury for the 5th exposition was chosen in May 1819, with the Duc de la Rochefoucauld as president and Fernand Chaptal as vice-president and rapporteur. Chaptal had arranged the 2nd and 3rd expositions, and again played a leading role. The 5th exposition opened on 25 August 1819 in the great halls of the Louvre Palace. The exposition last 35 days, with 1,662 exhibitors. It closed on 23 September 1819.

The 39 categories were much the same as in 1806, with the main emphasis on fabrics. Cashmere products were exhibited, but the jury noted that they could not compete in price with products made in India. Silk products showed advances in dying to create white and Prussian blue silk. New machines for carding and refining wool were displayed. As with the 1806 exposition, there were five levels of distinction: gold, silver and bronze medals, an honorable mention and a simple citation. Manufacturers who had won an award before could only receive a new award for a different product, or for a superior version of the old one. There were 886 awards. 84 gold medals were awarded. These included: Gold medal: Jean-Baptiste Marie Chaptal de Chanteloup (Jean-Antoine Chaptal's son) for the chemicals industry category. Gold medal: Marie-Jeanne-Rosalie Desarnaud-Charpentier for her dressing table Gold medal: Édouard Sévène in Rouen The King also rewarded many of the scientists, artists and manufacturers with the Legion of Honour or even the title of Baron. Joseph Marie Jacquard was awarded a medal of the Legion of Honour for his loom.

6th exposition (1823)

Louis XVIII ordered another exposition for 1821, but events forced a delay until 1823. In January 1823 the Minister of the Interior announced that an industrial exposition would be held in the Louvre from 25 August 1823 to 15 October 1823, with the same instructions as in 1819 sent to the departments of France. The exposition was again held on the ground floor of the Louvre. The exposition lasted 50 days, with 1,642 exhibitors. The emphasis was on industry, but some luxury goods were exhibited including two vases by the Manufacture de Nast of Henri and François Nast. Although fabrices still featured prominently there were more metal products than before showing the recent advances in metallurgy. A model was exhibited of a planned suspension bridge which would span the Rhône from Tain-l'Hermitage to Tournon-sur-Rhône. The bridge, designed by Marc Seguin, was completed in 1825.

7th exposition (1827)

The 7th exposition was held in 1827 under the reactionary King Charles X of France, who would soon be deposed. It was held in a time of economic uncertainty, but still attracted more than 600,000 visitors. The exposition lasted 60 days, with 1,695 exhibitors. 1,254 prizes were awarded. Jérôme-Adolphe Blanqui wrote an independent history of the exposition in which he attacked high taxes that penalized industry and protectionism that harmed consumers.

July Monarchy

The first exposition of the July monarchy was planned for 1832 but had to be cancelled due to riots followed by a cholera epidemic. In October 1833 it was decreed that there would be an industrial exposition in Paris every five years, starting in 1834. The 1839 exposition was staged on schedule, as would be the next two expositions.

8th exposition (1834)

Four large buildings were designed for the 1834 exposition by M. Moreau and erected in the Place de la Concorde between La Madeleine and the Palais Bourbon. The buildings had simple exterior decoration and were generally well-made, apart from some problems with rain leaking in. Each building was divided into four long aisles and contained a courtyard. The exposition ran from 1 May 1834 to 30 June 1834. There were 2,447 exhibits in an area of . The exposition lasted 60 days, with 2,447 exhibitors.

Commissioner Adolphe Thiers notified the departmental prefects of the criteria for submissions, saying that the exhibits should mainly be products for the masses, and ideally would combine high quality and low price. Entries were divided into categories of use: food and food preparation; health; weaving processes and clothing; home products; transportation; products for smell, hearing, etc.; calculation, measurement and applied engineering; education and training; and social amenities. The categorization caused confusion among the visitors. Charles Dupin of the Institut Français, a famous statistician, was named rapporteur for the central jury of 1834. For each branch of industry he noted the quantities and value of French exports and imports, with comparative figures for 1823, 1827 and 1834.
