Friedrich Welwitsch discovered the plant Welwitschia mirabilis in the Namib Desert in 1859, a find that brought him global scientific recognition. Born in 1806 in Maria Saal, he abandoned a career in medicine to dedicate his life to botany, eventually becoming a prolific explorer whose extensive collections defined his contribution to the nineteenth-century natural sciences.
Early Career and Transition to Botany
Educated at the University of Vienna, Welwitsch initially practiced medicine in the Austrian provinces of Carniola and Moravia. Despite his father’s desire for him to pursue law, his botanical interests led him to abandon medicine in 1839. He soon moved to Portugal with funding from a Württemberg botanical association, where he directed botanical gardens and initiated the distribution of plant series such as Welwitschii iter Lusitanicum.

In 1853, Welwitsch began research in Angola on behalf of the Portuguese government. During eight years of exploration, he cataloged a vast array of flora, including his discovery of Rhipsalis baccifera, a cactus species found in Africa. His most significant finding was the gymnosperm Welwitschia mirabilis, a unique plant capable of living for centuries. He also described numerous other species, including the Butter Tree and Devil's Trumpet.
Professional Legacy in London
Welwitsch relocated to London in 1863 to work at the Natural History Museum and Kew Gardens. His publication Sertum Angolense identified 12 new categories and 48 species. Following his death in 1872, a legal dispute between the Portuguese government and London institutions regarding his estate resulted in the collection being divided between Lisbon and London. He is buried at Kensal Green Cemetery.
