Lost Horizon first published in 1933, this novel won Hilton the Hawthornden Prize in 1934. Hilton is said to have been inspired to write Lost Horizon, and to invent "Shangri-La" by reading the National Geographic Magazine articles of Joseph Rock, an Austrian-American botanist and ethnologist exploring the southwestern Chinese provinces and Tibetan borderlands. Still living in Britain at the time, Hilton was perhaps influenced by the Tibetan travel articles of early travelers in Tibet whose writings were found in the British Library.
