Tryggve Gran

Jens Tryggve Herman Gran (20 January 1888 – 8 January 1980) was a Norwegian aviator, polar explorer and author.

He was the skiing expert on the 1910–13 Scott Antarctic Expedition and was the first person to fly across the North Sea from Scotland to Norway in a heavier-than-air aircraft in August 1914. During WW1 he joined the Royal Flying Corps and flew night bombing raids on the Western Front, for which he was awarded the Military Cross. He co-piloted the first flight from London via Oslo to Stockholm in 1920.

During WWII he aligned himself with Vidkun Quisling's ruling party, and was sentenced to 18 months in prison in 1948. Provided by Wikipedia
