Sir Arnold Henry Moore Lunn (1888 – 1974) skier, mountaineer and writer.

He was knighted for "services to British Skiing and Anglo-Swiss relations" in 1952. His father was a lay Methodist minister, but Lunn was an agnostic and wrote critically about Catholicism before he converted to Catholicism at the age of 45 and became a Catholic apologist. He was born in Madras, India and died in London.
