Anton Rzehak

Anton Rzehak (26 May 1855 in Neuhof, near Nikolcitz – 31 March 1923 in Brno) was a Moravian geologist, paleontologist and prehistorian.
He studied chemistry and geology at the University of Technology in Brünn, where from 1880 to 1884, he worked as an assistant to Alexander Makowsky (1833–1908). In 1883 the two men published a geological map on the environs of Brünn.
From 1884 to 1905 he taught classes in chemistry and natural history at a secondary school in Brünn, and in the meantime, obtained an associate professorship for paleontology and applied geography (1902). In 1905 he was named chair of mineralogy and geology at the technology university in Brünn.
The foraminifer genus Rzehakina bears his name.
In Gabon, for example, the Last Apparition Date of fossil foraminifer "Rzehakina epigona" marks a point in time very close to the end of the Paleocene epoch, making it a biostratigraphically important species.
