Nick Estcourt (1942 - 12 June 1978), educated at Eastbourne College, was a British climber killed on K2 by an avalanche on the West Ridge route. He took part in the 1970 British Annapurna South Face expedition. One of his notable achievements, with Paul ('Tut') Braithwaite was the first ascent of the Rock Band, a line of cliffs on the expedition to the South West Face of Everest in 1975 that had defeated several previous expeditions.
