About the author
Born in Vienna on March 11, 1863, Franz Thonner was an Austrian botanist, taxonomist, explorer, and ethnographer. He is remembered especially for his studies of flowering plants and for creating analytical keys that helped readers identify plant families more easily.
In 1896, he traveled into the northern Congo Basin, where he collected plants and documented local communities. That journey shaped much of his later work, including botanical publications based on African material and writings that drew on his field experience.
Thonner continued publishing on plant classification for many years, and his name remains associated with practical botanical reference works. He died in Prague on April 21, 1928.
