August Kappler (11 November 1815 – 20 October 1887) was a German researcher, naturalist and explorer who was a native of Mannheim.
From January 1836, Kappler was stationed in Suriname as a soldier and member of the Dutch colonial service.
Here he had the opportunity to explore the country, and in the process, amass a large collection of insects and plants.
After his military duties were finished, he spent the years 1842 to 1846 based in Paramaribo, from where he sold butterflies that were collected locally.
In 1879 Kappler left Suriname and returned to Germany, subsequently publishing two more books on his experiences in the Dutch colony.
