James Ramsey Ullman
The books he wrote were mostly about mountaineering and geography.
His works include Banner in the Sky (which was filmed in Switzerland as Third Man on the Mountain), and The White Tower (which would star Glenn Ford and Lloyd Bridges). Also Americans on Everest by James Ramsay Ullman, page 195, published by J. B. Lippincott Company 1964, Library of Congress Catalogue #64-14475.
He was the ghost writer for Tenzing Norgay's autobiography Man of Everest (originally published as Tiger of the Snows). High Conquest was the first of nine books for the J.B. Lippincott company coming out in 1941 followed by The White Tower, River of The Sun, Windom's Way, and Banner in the Sky which was a 1955 Newbery Honor book. All of these titles became small motion pictures.
Ullman also authored John Harlin's biography Straight Up.
He also wrote the short story "Top Man", a story about mountaineers climbing K3, a mountain in India. The story appears in several anthologies. It was originally published in the Saturday Evening Post in 1940. Issue #35.
Beyond his mountaineering books, he wrote "Where the Bong Tree Grows," an account of a year he spent traveling through some of the most remote islands of the South Pacific. Ullman also wrote a novel about the poet Arthur Rimbaud, The Day on Fire (1958).
He joined the American Mount Everest Expedition 1963 as official historian. Because of health problems he had to stay in Kathmandu. His book Americans on Everest: The Official Account of the Ascent was published in 1964.
