1665–1789: Manufacture royale Since the mid-17th century, luxury products such as
silk textiles,
lace, and
mirrors were in high demand. In the 1660s, mirrors had become very popular among the upper classes of society: Italian
cabinets,
châteaux, ornate side tables, and
pier-tables were decorated with these expensive and luxurious products. At the time, however, the French were not known for mirror technology; instead, the
Republic of Venice was known as the world leader in
glass manufacturing, controlling a technical and commercial
monopoly of the glass and mirror business. As a result, French Minister of Finance
Jean-Baptiste Colbert wanted
France to become completely
self-sufficient in meeting
domestic demand for luxury products, thereby strengthening the national economy. Colbert established, by
letters patent, the public enterprise
Manufacture royale de glaces de miroirs (,
Royal Mirror-Glass Factory) in October 1665. The company was created for a period of twenty years and would be financed in part by the state. The beneficiary and first director was the French financier Nicolas du Noyer, a
receiver of taxes of Orléans, who was granted a monopoly of making glass and mirror-glass for twenty years. The company had the informal name
Compagnie du Noyer. To compete with the Italian mirror industry, Colbert commissioned several Venetian glassworkers he had enticed to Paris to work for the company. The first unblemished mirrors were produced in 1666. Soon the mirrors created in the
Faubourg Saint-Antoine, under the French company, began to rival those of Venice. The French company was capable of producing mirrors that were , which at the time, was considered impressive. Competition between France and the Venetians became so fierce that Venice considered it a crime for any glass artisan to leave and practice their trade elsewhere, especially in foreign territory. Nicolas du Noyer complained in writing that the Venetians were unwilling to impart the secrets of glassmaking to the French workers and that the company was hard-pressed to pay its expenses. Life in Paris proved distracting to the workers, and supplies of firewood to stoke the furnaces were dearer in the capital than elsewhere. In 1667, the glass-making was transferred to a small glass furnace already working at Tourlaville, near Cherbourg in Normandy, and the premises in Faubourg Saint-Antoine were devoted to glass-grinding and polishing the crude product. Though the
Compagnie du Noyer was reduced at times to importing Venetian glass and finishing it in France, by September 1672 the royal French manufacturer was on a sufficiently sound footing for the importation of glass to be forbidden to any of Louis' subjects, under any conditions. In 1678, the company produced the glass for the
Hall of Mirrors at the
Palace of Versailles. In 1683, the company's financial arrangement with the State was renewed for another two decades. However, in 1688 the rival
Compagnie Thévart was created, also financed in part by the state.
Compagnie Thévart used a new pouring process that allowed it to make
plate glass mirrors measuring at least , much bigger than the that the
Compagnie du Noyer could create. The two companies competed for seven years, until 1695 when the economy slowed down and their technical and commercial rivalry became counterproductive. Under an order from the French government, the two companies were forced to
merge, creating the
Compagnie Plastier. A mirror factory in the village of
Saint-Gobain in
Picardie gave its name to the present company. In 1702,
Compagnie Plastier declared
bankruptcy. A group of Franco-Swiss
Protestant bankers rescued the collapsing company, changing the name to
Compagnie Dagincourt. At the same time, the company was provided
royal patents which allowed it to maintain a legal monopoly in the glass-manufacturing industry up until the
French Revolution (1789), despite fierce, sometimes violent, protests from free enterprise partisans.
1789–1910: Industrial Revolution In 1789, as a consequence of the
French Revolution, the state financial and competitive privileges accorded to
Compagnie Dagincourt were abolished. The company had to depend on the participation and capital of private investors, although it continued to remain partly under the control of the French state. In the 1820s, Saint-Gobain continued to function as it had under the
Ancien Régime, manufacturing high-quality mirrors and glass for the luxury market. However, although in 1824, a new glass manufacturer was established in
Commentry, France, and in 1837, several Belgian glass manufacturers were also founded. While Saint-Gobain continued to dominate the luxury high-quality mirror and glass markets, its newly created competitors focused their attention on making medium and low-quality products. The manufacture of products of such quality made mirrors and glass affordable for the masses. In response, the company extended its product line to include lower-quality glass and mirrors. In 1830, just as
Louis-Philippe became King of the newly restored French Monarchy, Saint-Gobain was transformed into a
Public Limited Company and became independent from the state for the first time. While mirrors remained their primary business, Saint-Gobain began to diversify their product line to include glass panes for
skylights, roofs, and room dividers, thick mirrors, semi-thick glass for windows, laminated mirrors and glass, and finally embossed mirrors and windowpanes. Some of the more famous buildings that Saint-Gobain contributed to during that period were the
Crystal Palace in London,
Jardin des Plantes, the
Grand Palais and adjacent
Petit Palais in Paris, and the
Milan Central railway station. Saint-Gobain merged with another French glass and mirror manufacturer, Saint-Quirin, in the mid-19th century. After the merger, the company was able to gain control of 25% of European glass and mirror production (before, it had only controlled 10–15%). In response to growing international competition, the company began to establish up new manufacturing facilities in countries without any domestic manufacturers. Saint-Gobain cast the glass blanks of some of the largest optical
reflecting telescopes of the early 20th century, including the ground-breaking Hale telescope (online in 1908), the 61-inch (1.54 m) Bosque Alegre telescope built in 1912, for the
Argentine National Observatory, directed by
Charles D. Perrine, and 100 inch (2.5 m) Hooker telescope (online 1917) at
Mount Wilson Observatory (United States), and the Plaskett telescope (online in 1918) at
Dominion Astrophysical Observatory (
Canada). By the end of the 19th century, Saint-Gobain named the
Casa Pellandini “its sole representative and exclusive depositary throughout the Mexican Republic."
1910–1950: Post Industrial Revolution Saint-Gobain experienced significant success in the early 20th century. In 1918, the company expanded its manufacturing to bottles, jars, tableware, and domestic glassware. In 1920, Saint-Gobain extended its businesses to
fibreglass manufacturing. Fibreglass was being used to create
insulation, industrial textiles, and building reinforcements. In 1937, the company founded
Isover, a
subsidiary fibreglass insulation manufacturer. During this period, the company developed three new glassmaking techniques and processes; first, a dipping technique used to coat car windows, which prevented the glass from shattering in the event of an accident. As a result of that technique, 10% of Saint-Gobain's 1920 sales came from the car industry, and 28% in 1930. Second, a few years later, another technique was developed that allowed glass to be shaped and bent. Finally, a process was developed to coat glass with aluminum, allowing it to be used as a
conductor, and allowed the company to create products such as the ‘radiavers’ (French for “radiating glass”), a unique type of electric heater with the heating element encased in glass.
1950–1970: Pont-à-Mousson merger Between 1950 and 1969, Saint-Gobain's sales rose at a rate of 10% per year. Its workforce grew from 35,000 in 1950 to 100,000 in 1969. By the end of the 1960s, Saint-Gobain had more than 150 subsidiaries under its control. Glass and fibreglass sales benefited from the booming construction industry and the rise in mass consumption after the Second World War. Saint-Gobain's yearly glass production went from in 1950 to in 1969. In 1950, fibreglass only represented 4% of the company's turnover, but by 1969, this had grown to 20%. Domestic sales in France accounted for only a fifth of the company's revenue.
Spain,
Germany,
Italy,
Switzerland, and
Belgium were also important markets. In 1968,
Boussois-Souchon-Neuvesel, a French industrial group, made a
hostile takeover bid for Saint-Gobain. The company looked for a "
white knight" to help fend off the bid. Multinational corporation
Suez suggested that Saint-Gobain and Pont-à-Mousson (another French industrial group) should merge, to maintain independence from Boussois-Souchon-Neuvesel. After the merger,
Saint-Gobain-Pont-à-Mousson, later known simply by the name "Saint-Gobain", produced pipes in addition to glass and fibreglass.
1971–1986: Nationalisation The next fifteen years were a time of change and reorganization for the newly merged companies. In the 1970s, Western economies were suffering a sharp downturn. Saint-Gobain's financial performance was adversely affected by the economic and petrol crises. In 1981 and 1982, ten of France's top-performing companies were nationalized by the
socialist party-controlled
Fifth Republic of France. By February 1982, Saint-Gobain was officially controlled by the state. However, the company did not last long as a government-owned corporation; it was re-privatized in 1987.
1986–present: Expansion When Saint-Gobain once again became a private enterprise, control of the company quickly changed hands.
Jean-Louis Beffa, an engineer and graduate of the
École Polytechnique, became the
CEO. Beffa invested heavily in
research and development and pushed strongly for the company to produce engineered materials, such as abrasives and
ceramics. Under Beffa, the company continued to expand internationally, setting up foreign factories, and acquiring many of its foreign competitors. In 1996 the company bought Poliet (the French building and construction distribution group) and its subsidiaries, such as Point P. and Lapeyre. This expanded Saint-Gobain's product line into construction materials and their distribution. In 2005,
Olivier Bluche took the helm of Supply Chain Operations, quickly modernising the company's lengthy and dated processes. In October 2022, Saint-Gobain Films & Fabrics was renamed Saint-Gobain Composite Solutions. In 2023, the company's Indian arm acquired Twiga Fiberglass, a manufacturer of glass wool with production facilities located near Delhi and Mumbai. ==Company structure==
