The American Travel Journals

The journals of the American Journey (1799–1804) are the key source for understanding Humboldt’s travel work and provide the basis for the reappraisal of his scientific heritage. The approximately 3,500 pages combine descriptions of the itinerary with measurement results, literary travel sketches, scientific essays, drawings, and sketches.

The Russian-Siberian Travel Journals

The journals of the Russian-Siberian Journey (1829) consist of three parts: »Fragments of the Siberian Travel Journal 1829« and two journals with notes and measurements on geodesy and geomagnetism. The recordings of this journey provide the basis for Humboldt’s three-volume work on Central Asia.

Humboldt's Papers

In addition to the travel journals, the project edits selected collections from Humboldt’s personal papers: documents, letters, notes, and maps that are directly related to Humboldt’s hemispheric journeys. First, we focused on the topic life sciences, in particular Humboldt’s notes on phytogeography (editing period: 2015–2018). Since then, the focus has been on the topic scientific journeys.

The Project

At its core, the 18-year Academy Project involves the complete publication of Humboldt’s manuscripts on the topic of journeys at the intersection of cultural and natural sciences. These manuscripts provided Humboldt with a lifelong basis for writing the Personal Narrative, his American travelogue, as well as for elaborating the entire 29-volume oeuvre of his journey through the Americas. In his later days, they became a cornerstone for his work on Asie centrale (1843) and the Cosmos (1845–1862).
