Egon Schiele Biographical Information:Egon Schiele (1890-1918) is most famous for dying at such a young age and according to some before fulfilling his promise as an artist. However, his art career was approximately as long as van Gogh's if we pick his admission to the Vienna Academy of Fine Arts as its starting point.
Schiele left the Academy to start the Neukunstgruppe with other students who had become dissatisfied with the conservative curriculum.
Schiele broke many of the social norms of his day through his art and through his lifestyle. He was even imprisoned briefly for 'disseminating pornographic art.'
In 1915 he got married to Edith Harms and by 1918 he was beginning to have some economic success, when the influenza epidemic that killed 20 million people in Europe killed him and his pregnant wife.
