Gleim's collections are characterized by a unique connection between images, books and letters, and are in the service of his intense group of friendship; the collections became the property of the "Gleim Family Foundation" and were earmarked for public use. Gleim created a large portrait collection of writers and important contemporaries of the 18th century. While he at first only had his close friends painted, the circle of people painted expanded over the decades. At his death, the number of portraits was about 150; Today, the Gleimhaus preserves around 130 portrait paintings of 18th and early 19th century personalities, including portraits of
Ewald von Kleist,
Karl Wilhelm Ramler,
Johann Joachim Winckelmann,
Gotthold Ephraim Lessing,
Klopstock,
Anna Louisa Karsch,
Sophie von La Roche,
Johann Jakob Bodmer,
Salomon Gessner,
Wilhelm Heinse, and
Jean Paul. Many of the most important portraitists of the second half of the 18th century are represented by one or more works, such as
Anton Graff, Jens Juel, Georg Oswald May, Benjamin Calau, Gottfried Hempel, several members of the Tischbein family, Johann Friedrich Eich, Friedrich Georg Weitsch, Johann Heinrich Ramberg, and Georg Friedrich Adolph Schöner. Gleim's socialization led to an immense letter archive. Correspondents included the writers Lessing, Klopstock, Wieland, Ewald von Kleist and Herder, the poet Anna Louisa Karsch, the painter Bernhard Rode, the theologian Spalding and the esthetician Sulzer and the count's house Stolberg-Wernigerode. The manuscript collection of the Gleimhaus contains a total of around 10,000 letters from more than 500 correspondence from Gleim (originals, designs and contemporary transcripts, including more than 2,000 copies by Gleim, otherwise correspondence or letters from correspondence of the Gleim friends with third parties). There are also over 1,000 manuscripts (poetic bequests by Johann Wilhelm Ludwig Gleim, Jakob Immanuel Pyra, Ewald von Kleist, Johann Benjamin Michaelis, partial estate of Anna Louisa Karsch, occasional manuscripts by Friedrich Gottlieb Klopstock, Johann Peter Uz, Lessing, Ramler, Heinse, Johann Heinrich Voss and others). Moreover, Gleim's personal documents and his family are occasionally found, including some wallpaper left over from Gleim's summerhouse with handwritten notes by his friends. The convivial, scholarly, friendly and literary correspondence in North and Central Germany during the second half of the 18th century, concentrating on the connection between image, book and letter, is exemplified in the museum. Gleim's largely preserved book collection is considered one of the largest private bourgeois libraries of the 18th century; it comprises about 12,000 volumes, including over 50 incunabula, about 800 titles of the 16th century, about 1,200 of the 17th century. The largest part dates from the 18th and early 19th centuries, including numerous dedication copies. The library has its focus in European literature of the second half of the 18th century and also contains larger collections on literary and art history, economic, social, cultural and political history and natural sciences. These collections are the largest closed poetic estate of the 18th century at the historical site in the original collection conception and can be considered as the first literary archive of German works. The portrait collection and the letter archive are accessible via the homepage of the Gleimhaus. ==History==
