Yannick Seigneur, born May 24, 1941 in Paris and died November 28, 2001 in Passy (Haute-Savoie), is a mountaineer who has to his credit more than 500 route openings. Considered as one of the most brilliant guides of his generation, Yannick Seigneur is the first Frenchman to have recorded three “8000”.

He is the father of four children: Loic, Yann-Éric, Adriane and Raphaëlle. He spent his first ten years between Paris, where his father di him worked as a mover, and Megève, where his farmer grandfather taught him to herd sheep. At the age of 10, his parents told him to return to Megève, without his being interested in mountaineering.
