Wilhelm Storost, artistic name Vilius Storostas-Vydūnas (22 March 1868 – 20 February 1953), mostly known as Vydūnas, was a Prussian-Lithuanian[2] teacher, poet, humanist, philosopher and Lithuanian[3][4][5][6] writer, a leader of the Prussian Lithuanian national movement in Lithuania Minor, and one of leaders of the theosophical movement in East Prussia.

In 1912 he left his teaching position in order to take up philosophical studies, which he took at the universities of Greifswald, Halle, Leipzig and Berlin.

Back in Tilsit he dedicated himself to reestablishment of Lithuanian Culture, especially folks songs and rural traditions.

1932 he published the book Sieben Hundert Jahren Deutsch-Litauischer Beziehung (Seven Hundred Years of German-Lithuanian relations) focusing on German trade, military and religious colonization and genocide of Old Prussians.

Together with nearly all of the people of East Prussia he was expelled during the Soviet take-over and lived in a refugee camp for some time.

Pantheistic universalism, not predefined with participating in any obligatory religious practice, was one of the leading ideas of his philosophy, and gained him later fame as a pioneer of both pagan revival and theosophy in Lithuania.
