The foundation of the originally three museums traces back to the citizens of the city and to Johann Wolfgang von Goethe, who stayed in Wiesbaden in 1814/1815 for a rehabilitation measure, and worked hard to establish such a cultural institution.In 1825 he persuaded the Frankfurter private collector Johann Isaac Freiherr von Gerning [de] to donate his extensive collections of works of art, antiquities and in kind to the Duchy of Nassau in return for the payment of an annuity for life.Under the responsibility of the newly founded associations, but controlled by the ducal government, the citizens of Wiesbaden and the region were able to quickly expand these collections.Together with the pieces of the Verein für Nassauische Altertumskunde und Geschichtsforschung [de] ("Association for Nassauian Antiquity and Historical Research") founded in 1812, three originally independent museums emerged.Temporarily stored art treasures were shown, such as the bust of Nefertiti or the painting The Man with the Golden Helmet, which was attributed to Rembrandt at the time.Clemens Weiler[1] played a major role in the construction of the Alexej von Jawlensky-Collection, which is today the most important collection of the house.[5] In the freed south wing, the Old Masters are presented in connection with contemporary art The chronological sequence was abandoned in favour of spaces on the themes "religion", "portrait", "mythology", "still life" and "landscape".1910), Franz von Stuck, Georg Kolbe, Wilhelm Lehmbruck, Gerhard Marcks, Emy Roeder and Ernst Barlach (Der Tod, 1925).In the 19th century, on the other hand, there are a number of works by Ludwig Knaus, Arnold Böcklin, Hans von Marées and Max Slevogt, among others.Works by other artists of the time, such as Edvard Munch, Otto Dix, Oskar Kokoschka, Käthe Kollwitz and Pablo Picasso, can also be found.Constructivist works, including those by László Moholy-Nagy, the artist couple Robert Michel and Ella Bergmann-Michel, as well as Friedrich Vordemberge-Gildewart, form another focal point of the collection.The Deutschrömer – German artists and writers who lived in Rome – are represented by Anselm Feuerbach (Nanna, 1861), Arnold Böcklin and Hans von Marées.The Leibl-Kreis in Munich is represented extensively, especially by Wilhelm Trübner, but also Hans Thoma, Carl Schuch and Otto Scholderer are present with paintings in the collection.The collection of this century ends with the works of the main representatives of German Impressionism, Max Liebermann and above all Lovis Corinth, of whom the museum owns five paintings (Portrait von Frau Halbe, 1898) as well as Oskar Moll (Havelkähne, 1907) and Christian Rohlfs.The collection includes early works such as Stillleben mit Krug und Buch ("Still Life with Jug and Book", around 1902), many expressive major works such as Dame mit Fächer ("Woman with a Fan", 1909), Nikita (1910) or Selbstbildnis ("Self-portrait", 1912) and, above all, many works of the paintings in series, such as the variations Von Frühling, Glück und Sonne ("Of Spring, Happiness and Sun", 1917) or the Abstract Heads created in Wiesbaden as Kopf in Rot-Weiß-Gold ("Head in Red-White-Gold", 1927) and the meditations as Mein Geist wird weiterleben ("My Spirit will live on", 1935).In addition, the collection of the Wiesbaden art collector and patron Heinrich Kirchhoff was regularly exhibited, with which many modernist works could be shown.With the Nazi confiscation campaign under the title Entartete Kunst all modern works of art were removed from the museum, so that one had to start again after the war.High quality works were purchased from Paula Modersohn-Becker, Otto Mueller (Liebespaar) ("Love Couple", 1925), Emil Nolde, Walter Jacob, Conrad Felixmüller (Familienbildnis Kirchhoff, "Kirchhoff family portrait", 1920), Karl Hofer and above all from Jawlensky's companion Marianne von Werefkin (Schindelfabrik, "Schindel Factory", around 1910).After this great enrichment, further individual works from this collection were acquired, to mention above all Jawlensky's painting Heilandsgesicht: Ruhendes Licht ("Face of Salvation: Resting Light") from 1921.Among others, László Moholy-Nagy with his painting Architektur III (1920), Erich Buchholz, Walter Dexel as well as the post-war artists Klaus Staudt, Günter Fruhtrunk and François Morellet are included here.The American post-war art[11] is featured by some of its main protagonists by works of Mark Rothko, Ad Reinhardt and Agnes Martin.Also listed in the collection are artists such as Sol LeWitt, Donald Judd, Robert Mangold, Fred Sandback, Dan Flavin and Brice Marden.The painting of the 1970s and 1980s is portrayed by artists such as Georg Baselitz with his work Stillleben ("Still Life", 1969), Eugen Schönebeck, Jörg Immendorff and Thomas Bayrle.The most important artists in the collection are Dietrich Helms, Jeppe Hein, Rebecca Horn, Thomas Huber, Vollrad Kutscher, Ingeborg Lüscher, Christiane Möbus, Norbert Radermacher, Franz Erhard Walther and Dorothee von Windheim with her work Fassade III (in English Facade III) (1979).Alexei von Jawlensky (1865–1941) was an important Russian artist in the first half of the 20th century who spent the last twenty years of his life in Wiesbaden.In addition to a general mineral collection of worldwide origin, the focus is on finds from the region, which document in particular the mining industry, which was important until a few decades ago.In this change numerous animal species lived here, so there are traces of, amongst others, Manatees, Basking sharks, reef-forming mussel banks, but also land creatures, such as the Deinotherium, which was found in Eppelsheim.
