The presence of the family in the village of Puisseguin dates back to the Middle Ages. Marceau Dupuy, grandfather of Gerard, Doctor of Medicine and also politician, acquired the property Beauséjour in 1934.

Upon returning from the war in 1945, Alain Dupuy, his son, will take the wealth management by applying the teachings of his grandfather, Mr. Berthon, owner of Château Langlais.

Today, Gérard Dupuy, manages all the company.
