The archive, which preserves Haeckel’s voluminous estate (roughly 40,000 original letters to and by Haeckel as well as his manuscripts, notebooks, documents, water colours, oil paintings, drawings, etc.) and which holds his extensive research library, is one of the most important archives on the history of biology and cultural history at the end of the 19th and early 20th century. Haeckel’s correspondence, the central component of the archive, has been the focus of a long-term project of editing letters to and from HaeckelExternal link running since 2013 and funded by the Union der deutschen Akademien [Union of German Academies]. It will be published in its entirety as an online edition and in selected volumes in a historical-critical print editionExternal link.
A substantial part of Theodor Schwann’s estate was transferred to the archive in November 2021.
