SIR HUBERT WILKINS (1888-1958) was an Australian adventurer who gained international renown for his pioneering flights in the Arctic and Antarctic. In 1942, after having shifted his sphere of activities from polar exploration to working for the United States Army and various government agencies, he was introduced to the Urantia revelation. This revelation consisted of thousands of pages of manuscript said to have been transmitted by superhuman beings through an anonymous man living in Chicago. The enormous text was in the custody of a Chicago physician, William S. Sadler, who formed a secret group, the Forum, to study it. Wilkins became a member on March 5, 1942. Enthralled by his initial readings, he pored over the manuscript during his periodic visits to Chicago. In 1945 he began to keep a notebook, into which he copied passages from the text that he found especially significant or inspiring. When the Urantia Book was finally published in 1955, Sir Hubert was able to retrieve the notebook, which until then had been stored at Dr. Sadler's residence in Chicago. It was rediscovered in 2014, and is now being made public. It is a unique remnant of a largely obscure period in the history of the Urantia Book and its readership. Sir Hubert Wilkins was certainly the first internationally known person to embrace the Urantia text as a major revelation to this planet. This notebook is a testament to Wilkins' devoted study of a book that answered his most vital questions and gave him a new lens through which to view his own adventurous life.
