Richard Wettstein

Richard Wettstein (30 June 1863 – 10 August 1931) was an Austrian botanist. His taxonomic system, the Wettstein system, was one of the earliest based on phyletic principles.

Wettstein studied in Vienna under Anton Kerner von Marilaun and later married Kerner's daughter Adele. Their sons included the botanist Fritz von Wettstein and the zoologist Otto von Wettstein. His grandson Diter von Wettstein was a plant geneticist. During his time at the University of Vienna, he founded the student-led Natural Science Association with his friend Karl Eggerth in 1882.

He was a professor at the University of Prague from 1892, and at the University of Vienna from 1899. He newly laid out the Botanical Garden of the University of Vienna.

In 1901 he became president of the Vienna Zoological-Botanical Society (Zoologisch-Botanische Gesellschaft), and during the same year took part in a scientific expedition to Brazil. In 1919 he was appointed vice-president of the Vienna Academy of Sciences. During his later years (1929–30), he traveled with his son, Friedrich, to eastern and southern Africa.

The mycological genus Wettsteinina and the Wettsteiniola genus of flowering plants from Brazil, belonging to the family Podostemaceae, are both named for Richard Wettstein.

In 1905, he was co-president of the International Botanical Congress, held in Vienna.
