Seventeen letters sent by Ludwig Leichhardt from 1842–48 vividly depict his stay in Australia. In this exhibition curated by historian Heike Hartmann, we are introducing a brand new English translation of the letters and a timeline tool with which to view those, this virtual exhibition documents Leichhardt’s adventurous stay in Australia and opens up new perspectives for the environmental history of the land, Europeans’ engagement with its indigenous population, and international scientific networks at the time.
