Eduard Suess (German: [ˈeːduaʁt zyːs]; 20 August 1831 – 26 April 1914) was an Austrian geologist and an expert on the geography of the Alps.

[7] Suess published a comprehensive synthesis of his ideas between 1885 and 1901 titled Das Antlitz der Erde (The Face of the Earth), which was a popular textbook for many years.

In volume two of this massive three-volume work,[8] Suess set out his belief that across geologic time, the rise and fall of sea levels were mappable across the earth—that is, that the periods of ocean transgression and regression were correlateable from one continent to another.

In his work Die Entstehung der Alpen, Suess also introduced the concept of the biosphere, which was later extended by Vladimir I. Vernadsky in 1926.

The plant, whose deep roots plunge into the soil to feed, and which at the same time rises into the air to breathe, is a good illustration of organic life in the region of interaction between the upper sphere and the lithosphere, and on the surface of continents it is possible to single out an independent biosphere.He was elected a member of the American Philosophical Society in 1886[10] and the Royal Swedish Academy of Sciences in 1895.

[12][13] His son, Franz Eduard Suess (1867–1941), was superintendent and geologist at the Imperial Geological Institute in Vienna,[14] who studied moldavites and coined the term tektite.
