About the author
Born in Vienna in 1863, Franz Thonner was an Austrian taxonomist, botanist, explorer, and ethnographer who worked largely as an independent scholar. He traveled widely in Europe and North Africa, then in 1896 made a major journey into the northern Congo Basin, where he collected plants and recorded observations on local peoples, languages, and everyday life.
His writing grew directly out of that field experience. Alongside travel journals and ethnographic notes, he produced botanical reference works and analytical keys for identifying plants, including broad guides that aimed to be useful in the field rather than only in specialist collections.
Thonner died in Prague in 1928. He is remembered both for his African travel narratives and for botanical manuals that continued to be valued and translated long after their first publication.
