Franz Ryba (geologist)

Franz Ryba (born July 2, 1867 in Chotěboř , † May 18, 1918 in Příbram ) was a Czech geologist and paleontologist.

Ryba first studied Slavic, German, aesthetics and philosophy and then geology and paleontology at the Bohemian University in Prague , where he was a student of the paleontologist Otomar Novak (1851-1892), and at the University of Vienna . In 1895 he became an assistant and in 1899 adjunct at the mining academy in Příbram, where he received his doctorate in 1900 (about the chrome iron ore deposit of Kraubat) and where he qualified as a professor in 1903 in petrography. In 1905 he became an associate professor and finally, as the successor to Adolf Hofmann, a full professor. He is buried in his hometown.

He was a paleobotanist and was considered an expert on the flora of the Central Bohemian coal. His paleobotanical research also led to re-evaluations of the stratigraphy of the Permian and Carboniferous layers in Bohemia. Ryba also dealt with Bohemian ore deposits.

He was a corresponding member of the Royal Bohemian Society of Sciences in Prague and became a member of the Paleontological Society in the founding year 1912 .
