K2 also became popularly known as the "Savage Mountain" after George Bell—a climber on the 1953 American Expedition—told reporters, "It's a savage mountain that tries to kill you." Of the five highest mountains in the world, K2 is the deadliest; approximately one person dies on the mountain for every four who reach the summit. Also occasionally known as "Chhogori", or "Mount Godwin-Austen", other nicknames for K2 are "The King of Mountains" and "The Mountaineers' Mountain", as well as "The Mountain of Mountains" after prominent Italian climber Reinhold Messner titled his book about K2 the same.
