Born in Germany, Ralph Schwieger kept from his origins the memory of forest's smell of moss and wood. Chemist by formation, he gets in Roure Bertrand Dupont when he is thirty. His already strong technique allows him to transcribe his ideas into his compositions. He talks about his profession like a construction game, half cerebral, half intuitive, like a game that starts by an intellectual and conceptual phase followed by a long sensual, almost tactile research. His very architectured writing and his desire to compose perfumes that are out of the ordinary give his work an unusual personality.
