Jørgen Jørgensen (name of birth: Jürgensen, and changed to Jorgenson from 1817) (29 March 1780 – 20 January 1841) was a Danish adventurer during the Age of Revolution. During the action of 2 March 1808 his ship was captured by the British. In 1809 he sailed to Iceland, declared the country independent from Denmark and pronounced himself its ruler. He intended to found a new republic, following the examples of the United States and the French First Republic. He was also a prolific writer of letters, papers, pamphlets and newspaper articles covering a wide variety of subjects, and for a period was an associate of the famous botanists Joseph Banks and William Jackson Hooker. He left over a hundred written autographs and drawings, most of which are collected in the British Library. Marcus Clar
