Karl Alfred Ritter von Zittel (25 September 1839 – 5 January 1904) was a German palaeontologist.

He was born at Bahlingen in the Grand Duchy of Baden, and educated at Heidelberg, Paris and Vienna. For a short period he served on the Geological Survey of Austria, and as assistant in the mineralogical museum at Vienna. In 1863 he became teacher of geology and mineralogy in the polytechnic at Karlsruhe, and three years later he succeeded Oppel as professor of palaeontology in the university of Munich, with the charge of the state collection of fossils.

In 1880 he was appointed to the geological professorship, and eventually to the directorship of the natural history museum of Munich. His earlier work comprised a monograph on the Cretaceous bivalve mollusca of Gosau ;(1863–66); and an essay on the Tithonian stage (1870), regarded as equivalent to the Purbeck and Wealden formations.

In 1873-74 he accompanied the Friedrich Rohlf's expedition to the Libyan desert, the primary results of which were published in Uuml;ber den geologischen Bau der libyschen Wuste(1880), and further details in the Palaeontographica (1883). Dr Zittel was distinguished for his palaeontological researches. From 1869 until the close of his life he was chief editor of the Palaeontographica (founded in 1846 by W Dunker and H von Meyer).(Image and text: Wikipedia)

Karl von Haushofer (Munich, April 28, 1839 - January 8, 1895) was a scholar and professor of mineralogy. Son of Max Haushofer landscape painter and older brother of the economist Max Haushofer Jr., Karl Haushofer studied between 1857 and 1863 in Munich, Prague and Freiberg. After two years of practice in the steel industry, in 1865 he qualified as Associate Professor of Mineralogy at the University of Munich. In 1868 he was appointed professor of mineralogy and metallurgy at the Technische Hochschule in Munich, school of which he became director in 1892. His studies led to important results in physics of crystals. Among his works we must include the collaboration with von Zittel in editing Palaeontologische Wandtafeln series for which Haushofer created images of geological landscapes. He was co-founder of the German Alpine Club of which he oversaw for several years the official magazine for several years. Nel 1887 Haushofer was elected a member of the Leopoldina.

Josef Felix Pompeckj (May 10, 1867, Groß-Köllen July 8, 1930, Berlin) was a German paleontologistand geologist.

He was born in Groß-Köllen (now Kolno in Poland). He studied geology and paleontology at the University of Königsberg, receiving his doctorate in 1890 with the thesis Die Trilobitenfauna der ost- und westpreußischen Diluvialgeschiebe. In 1903 he became an associate professor in Munich, and from 1904 taught classes in geology and mineralogy at the agricultural college in Hohenheim.

In 1907 he relocated to the University of Göttingen, where he eventually became a full professor of geology and paleontology. From 1913 he worked as a professor at Tübingen, then in 1917 moved to the University of Berlin as successor to Wilhelm von Branca. At Berlin, he was appointed director of Geologisch-Paläontologischen Institut und Museum. (Image and text: Wikipedia)

Hans Salfeld. He was a teacher of geology at the University of Göttingen and worked with prof. Pompeckj at the II series of the Palaeontologische Wandtafeln.

Caecilie Graf-Pfaff (Erlangen, August 5, 1868 (1862?) - Nuremberg, July 8, 1939) was a German painter and illustrator. Firsty married with the painter and engraver Wihl. Bafer, after his death, she married with the painter Oskar Graf. She studied with G. Max, Liezen-Mayer and N. Gysis. Early in her career, her style was influenced by Japanese art, then she worked with the Die Brücke movement and is now particularly appreciated for her landscape pantings. Caecilie Graf-Pfaff signed the parietal table "Die heissen Mammoth-Quellen im Yellowston Park" of the von Zittel collection.

Franz Joseph Andreas Nicolaus Unger (30 November 1800 in Gut Amthof near village Leutschach in Styria, Austria – 13 February 1870 in Graz) was an Austrian botanist
Initially, Unger studied law at the University of Graz. In 1820 he moved to Vienna to study medicine, in 1822 he enrolled at the Charles University in Prague. In 1823 Unger returned to Vienna and completed his medical studies in 1827.
From 1827 Unger practiced as a doctor in Stockerau near Vienna, from 1830 as a court physician in Kitzbühel, Tyrol. In 1836 he was named professor of botany at the University of Graz and also taught at the Joanneum (which became the Universalmuseum Joanneum and the Graz University of Technology); in 1850 professor of plant physiology in Vienna. In 1852 he travelled to Northern Europe and to the Orient. Unger retired in 1866 and lived on his farm near Graz.
Unger was one of the major contributors to the field of paleontology, later turning to plant physiology and phytotomy. He hypothesized that (then unknown) combinations of simple elements inside a plant cell determine plant heredity and greatly influenced the experiments of his student Gregor Johann Mendel. Unger was a pioneer in documenting the relationships between soil and plants . (Image and text: Wikipedia)

Josef Kuwasseg (Trieste, November 25, 1799 - Graz, March 19, 1859) was an Austrian landscape painter, lithographer and writer. Son of the merchant Josephus Kubasseg and of Rosa Hehemperger, Josef was the eldest of six children.

After the untimely death of his father, Josef went to live with an uncle in Luttenberg. His precocious talent earned him the support of some patrons. Heattended Zeichenakademie in Graz under the direction of Andreas J. Hardter and Josef August Stark. Since 1824 he worked for the publishers Grazer and Heribert Kaiser Franz Joseph Lampel. From 1826 to 1832, along with his younger brother Charles, he worked for the lithographic company of Matthäus brothers and Josef Trentsensky in Vienna as draftsman and lithographer.
