2018 marks the centenary of Egon Schiele's death. To coincide with this occasion the publication will present the painting collection of the Belvedere Vienna including highlights such as Eduard Kosmack, House Wall, Death and Girl, The E mbrace and Four Tr ees. The book provides an opportunity to study the artist's work processes in greater detail and to follow the fascinating routes taken by his works before reaching the museum. In 1918 the OEsterreichische Galerie under Director Franz M. Haberditzl was the first Austrian museum to acquire an oil painting by Schiele during his lifetime. Today the museum owns one of the top collections of paintings from the years 1907 - 1918 by the artist. The publication will examine each work separately and will answer questi ons with regard to their acquisition and subject as well as related works. At the same time, the results of the investigations into painting technique which the works have undergone since 2016 will be presented for the first time. Complementary essays the history of the collection and the changes to the stocks of Schiele's works which are taking place as a result of museum reforms, the exchange of pictures or the restitution of individual works.
