Over more than two decades Martin Boysen made huge contributions to British rock climbing, especially in North Wales where he discovered Gogarth in the 1960s. His numerous new routes, such as Nexus on Dinas Mot, The Skull on Cyrn Las and Capital Punishment on Ogwen’s Suicide Wall have become classics. He was also one of Britain’s leading mountaineers, taking part in Bonington’s teams on the South Face of Annapurna and on the South West face of Everest. In 1976 he made the first ascent of Trango Tower with Joe Brown. His newly published book, Hanging on, was shortlisted for the 2014 Bordman Tasker Prize.
