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, in order 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 crisis. In 1981, and 1982, ten of France's top-performing companies were nationalized by the socialist 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
