Mark the Mountain Guide author, Mark Seaton, is a British mountain guide who lives with his wife and children in the Chamonix valley. He guides climbers and skiers in the French, Swiss and Italian Alps. Seaton's accomplishments as a professional mountain guide include the first complete unassisted British guided ascent of the Eiger Nordwand with his client Charles Sherwood in 2007. In 2008, Seaton & Sherwood teamed up again to complete a traverse of Mont Blanc via an ascent of Aiguille Blanche de Peuterey, the most difficult 4000-m summit in the Alps. In 1996, Mark led Don Planner, the first blind man to climb

He does not appear to have been gifted as a composer, however, and it is not clear whether any works of his survive. Several works were published under his name during his lifetime, including four cello concertos, but these were likely composed by his close friend Daniel Auber.
