Friedrich von Berchtold

Count Friedrich Carl Eugen Vsemir von Berchtold, baron von Ungarschitz (; 25 October 1781 – 3 April 1876), was a German-speaking Bohemian physician and botanist of Austrian descent.

Biography Berchtold was born in Stráž nad Nežárkou (now Jindřichův Hradec District), in the Austrian Empire. He graduated from medical school in 1804, after which he practiced medicine and devoted much of his time to botany and natural history. He eventually abandoned regular medical practice and travelled throughout Europe, the Middle East and Brazil. He co-authored several research papers with brother botanists Carl Borivoj Presl and Jan Svatopluk Presl, including an important taxonomic work, O Přirozenosti Rostlin.
