Tegner was the son of politician and businessman Jørgen Henry August Tegner and his wife Signe Elisabeth Puggaard. He travelled to Greece and to Italy as a young man, where he was particularly impressed by Michelangelo's sculptures in the Medici Chapel. His first major work, A Faun was installed at Charlottenburg Palace. From 1890 to 1893 he collaborated with the Norwegian sculptor Gustav Vigeland, and then moved to Paris, where he resided until 1897. Tegner's sculptures developed the stylistic innovations of Art Nouveau and the erotic realism of Auguste Rodin. This caused widespread debate in Denmark, which was still heavily influenced by the restrained neo-classical ideals of Bertel Thorvaldsen. Tegner, in contrast, emphasised violent monumental forms which were both eye-catching and provocative. Tegner was influenced strongly by the ideas of Frederich Nietzsche, especially as filtered through the writings of Georg Brandes. He created a statuette entitled Lucifer with Brandes's Head, a reference to Brandes' nickname "Lucifer". It has been described as showing the author as if he were "almost like his own worst enemy, or at least seems unafraid of aiming barbs at himself." Images of struggling figures influenced by Nietzschean ideas run throughout his work. Brandes himself defended Tegner's most controversial work, a monument to the physician and Nobel LaureateNiels Finsen, which was installed in Copenhagen in 1909. It shows a standing naked man flanked by two kneeling naked women, reaching up to the sky. The sculpture was entitled Mod lyset. It symbolised Finsen's principal scientific theory, that specific wavelengths of sunlight have healing properties. In 1911 Tegner married the painter Elna Jørgensen. In 1916, he acquired barren uncultivated land in Zealand in the vicinity of Helsingør. He subsequently built a museum and sculpture park dedicated to his work in this bleak landscape. From 1917 on he installed a number of his sculptures there, mainly on classicalthemes. He also created a building in an uncompromising minimaliststyle to function as a museum for his work. He is buried in a mausoleum at the centre of the complex, which is open to the public.
