for Humboldt imagery, you can browse along our category archive for “Portraits” or, for broader imagery on his American travels, the categories “Landschaftsmalerei” and “Amerika-Reise”.

To be certain about copyright issues, I recommend the Humboldt gallery at Wikimedia Commons.

For a good visualization tool concerning his American travels, see the Time Line Navigation by the Humboldt Digital Library.

For contemporary scholarship on Humboldt studies, I recommend the Video Lecture by Ottmar Ette “TransTropics. Alexander von Humboldt and the hemispheric constructions”.

Please tell us when the PBS documentary is done and online (?) so we can share the information.

best,
