Wilhelm Sievers

Friedrich Wilhelm Sievers (3 December 1860 – 11 June 1921) was a German geologist and geographer. He served as professor of geography at the university of Giessen.

Sievers was born into a merchant family in Hamburg. He broke the mercantile family tradition in order to study the emerging academic field of geography, being one of Ferdinand von Richthofen's first students.

Sievers made three expeditions to South America, mainly focusing on documenting evidence for a South American ice age. In 1909, he established the sources of the Marañon, the main source of the Amazon river.

Wilhelm Sievers published the "Allgemeine Länderkunde" (several editions 1891-1935), which for several decades was the leading international geographical publication covering all continents.

Sievers' botanical author abbreviation is "W.Siev.".
