Born in 1873 in a rural family in the Saumur region, Edouard Langlois was a winemaker and a cellarman at St-Hilaire-St-Florent. He was 23 years old when he married 19-year-old Jeanne Chateau, whose family came from Vendée.

On August 1, 1912, the couple founded the family company Maison Langlois-Chateau at St-Hilaire-St-Florent, with the help of Baron de Bodman, owner of Château de St-Florent and the adjoining vineyard; the Baron would thus bring cellars, land, and buildings to the young firm which, also, bought the business of the former Maison Delandes, founded in 1885.

Langlois-Chateau specialized immediately in the production of “sparkling wines”. Business started off weell, but was interrupted by World War I during which Edouard Langlois was killed on March 31, 1915. He was 42 years old and had been awarded the Croix de Guerre (Military Cross).
His young widow took over the management of the business, later aided by her son-in-law, Maurice Leroux and her son, Alexis.

In 1973, Maison Bollinger, a family enterprise at Aÿ-Champagne, recognized the quality of Langlois-Chateau wines and acquired majority ownership, thus contributing its financial resources as well as its agencies in France and abroad. Michel Villedey, a son-in-law of the Bollinger family and also from Saumur, became president of the firm, assisted by Jean Leroux, son of Maurice.
