Transcription:"Just returned from France, I find 2 cups on my table. from you, and thank you for that. The flora of the Rothliegen deals with three ferns that are very interesting to me. The smaller message deals with my culm flora. I'm sorry that you didn't get the third booklet that was in print at the same time as the two finished booklets; You would then certainly have found just as great a gap between the flora of the Schaltzlar strata as you noticed between the flora of the roofing slate and the Ostrava strata. The expression 'Ostrauer-Dachschiefer' is a mistake that can only cause confusion. With best thanks, D. Stur."

Dionys Štúr (in modern Slovak Dionýz Štúr, actually Dionýs Rudolf Josef Štúr, in German-language publications mostly Dionys Stur; * 5 April 1827 in Beckov, Austrian Empire, now Slovakia; † 9 October 1893 in Vienna) was a Slovak geologist and paleontologist who played a key role in the fundamental systematic geological exploration of the Alps, especially the Tauern.

Life and work: In addition to the geology of the Alps and the Carpathians, paleobotany, in particular the description of fossil plants from the Bohemian Paleozoic, was one of his specialties.

He was a member of the Kaiserlich-Königlich Geologische Reichsanstalt in Vienna, founded by Emperor Franz Josef I in 1849, from the year it was founded. With the work of the chief geologist Marko Vincenc Lipold and his two assistant geologists Stur and Carl Ferdinand Peters, the exploration of the Tauern Window was advanced from there from 1853, among other things with the aim of precise mapping. Stur took over the inspection of the main Tauern ridge and then worked out the major division of the area, which is still valid today. In 1854 he coined the term "slate shell" and in 1856 he published a series of profiles from the central gneiss to the eastern Alpine crystalline.

In 1869, Stur's report, commissioned by the Vienna City Council, on the soil conditions of the areas planned for the planned Vienna Central Cemetery ultimately led to its final location.

In 1877 he became vice director of the Imperial and Royal Geological Institute and was its director from 1885 to 1892. From 1872 he was a corresponding member of the Imperial Society of Natural Scientists in Moscow.

His successor in Vienna was Guido Stache.

Honours: The Leopoldina made him a member in 1890 and honored him in the same year with the Cothenius Medal as an author of particularly important scientific work.[2] The fossil plant genera Sturia Nemejc and Sturiella CEWeiss ex Potonié are named after Stur.

Geology Institute of Slovakia: The Slovak State Geology Institute bears his name (Štátny geologický ústav Dionýza Štúra).

Christian Ernst Weiss, also Weiss (* 12. May 1833 in Eilenburg; † 4 July 1890 in Schkeuditz) was a German mineralogist, geologist and phytopalaeontologist. He is the nephew of mineralogist Christian Samuel Weiss. Its botanical author abbreviation is "CEWeiss".

Life: Christian Ernst Weiß was the son of the Eilenburg ironmonger Friedrich Weiß and Charlotte Auguste née. Schmidt. First he attended the boys' school in Eilenburg. Since both parents died before he was ten, relatives from Merseburg took over the education of the gifted student. After successfully completing high school in Merseburg, Weiß began studying geology and mineralogy at the University of Halle in 1854, moving a year later to the Friedrich Wilhelm University in Berlin, where he learned from Heinrich Ernst Beyrich, Gustav Rose, Carl Ritter and was taught to his uncle Christian Samuel Weiß. In 1858, even before he received his doctorate, he earned his teaching qualification (“pro facultate legendi”) at the University of Berlin. In 1859 he was awarded a Dr. phil. PhD.

In 1860 Weiß accepted a call to lecture at the Bergschule in Saarbrücken. During his seven years of teaching in Saarbrücken, he dealt with the geological exploration of the "Palatinate-Saarbrück coal mountains and with phytopalaeontological studies". Especially as a phytopalaeontologist, he achieved groundbreaking research results during this time. In 1868 Weiß was appointed a member of the Geological State Institute in Bonn and then moved to the Rhine, where he habilitated as a lecturer in mineralogy and geology at the University of Bonn.

After Ferdinand Zirkel left for Leipzig, Weiß was appointed full professor of mineralogy, geognosy and geology at the University of Kiel. However, Weiß decided otherwise, took up the professorship for mineralogy at the Bergakademie Berlin in 1872 and became a state geologist in Berlin. In addition to the geological survey, which was accompanied by a corresponding journalistic activity in the form of numerous maps and explanations, Weiß continued to work in the field of paleontology. His focus was the systematic recording of organic remains and the determination of their relationship to living forms. By determining their geological distribution in the rock layers, clues should be gained to identify structures of the same and different ages. With the four volumes of the contributions to the fossil flora (1888) he left a comprehensive work on his research work. In 1882 he became a member of the Leopoldina.

At 4. On July 1, 1890, Weiß died at the age of 57 in Schkeuditz near Leipzig after a long illness. Parts of his legacy are now in the special paleobotanical library at the Museum für Naturkunde Chemnitz and in the teaching and research collection at the Technical University of Berlin.
