The French lawyer and winegrower Baron Pierre Marie Gabriel Le Roy Boiseaumarié (1890-1967) was a fighter pilot after studying law in the First World War from 1914 to 1918. In 1919 he married Emma Bernard Le Saint, heiress of the Château Fortia on the southern Rhône. In his new role as owner of the winery, he faced major problems in the department Vaucluse faced. Through the devastation of the phylloxera there had been a decline in wine quality. Adulteration with grapes from other areas such as the department Gard were the order of the day. Already in 1923 he defined an area which, according to his analyzes (today one would say: after ecological ) was best suited for viticulture. His criterion was the wild plants thyme and lavender growing here together. For this area he determined the grape varieties that are still valid today and are best suited due to the soil and climate. He is the founder of the appellation, which was only classified in 1935 Châteauneuf-du-Pape,
Boiseaumarié also tried very successfully to mobilize the winegrowers for his ideas. That is why he founded a winegrowers' association in Châteauneuf-du-Pape in 1924 and the Union Côtes du Rhône in 1929. In 1930 he founded the L'Académie du Vin de France with the restaurateur and writer Maurice E. Sailland alias Curnonsky (1872-1956) based on the model of the Académie Française. And with the friend of Agriculture Professor Joseph Capus (1868-1947) became the forerunner of today's in 1935 INAO created when its president Boiseaumarié acted for 20 years from 1947 to 1967. Boiseaumarié and Capus are considered to be the founders and pioneers of the French system of origin (see Appellation d'Origine Protégée ). For his services to the quality of wine, Pierre Boiseaumarié was appointed officer of the Legion of Honor and president of the OIV (Organization Internationale de la Vigne et du Vin).
