Caroline Rosenberg (1810 - 1902)

From 1838 to her death, she lived at Hofmansgave. Here, CR found his field of action. Encouraged by Hofman Bang, she began studying botany after taking a detour over the Latin in order to familiarize herself with systematic botanical works. She worked especially with algae and mosses, inspired by a former house teacher at Hofmansgave, botanist and pastor Chr. Lyngbye, who in 1819 had published her main work on algae in the Danish flora Tentamen Hydrophytologiae Danicae.

Both in the area around Hofmansgave and on his travels, not least in Norway, CR collected during his long life considerable amounts of seaweed and thus found the first ever red algae Helminthocladia purpurea by Skagen.

CR's list of algae genera, found in Denmark, was included in the Handbook in the Danish Flora and is her only overall scientific contribution to the botanical literature. Her efforts in the field of phycology, the doctrine of algae, have, however, been of importance in contemporary and retrospective, and contributions from her hand in the form of herbarium specimens have been recorded in several places, among other things. in Flora Danica. Also her studies of moss species were quite extensive, and not least her collection from Norway is valuable. She gave it to a Norwegian botanist who baptized a new mosart Bryum Rosenbergi in recognition of her work.

Bernhard Casper Kamphøvener (1813 - 1846)

Kamphøvener was the golden age of botany "James Dean". Kamphøvener first came into the pharmacy in the birthplace of Køge, then in Viborg, from where he fled to Copenhagen to study botany, which had interested him since he was a boy.

He studied at the University of Copenhagen from 1831 and lived at the Borch College. From 1837 he was an associate professor in front botany. He made several botanical trips in Denmark. His rich diary notes have been preserved at the Botanical Central Library - some were published posthumously. After the Nordic Nature Explorer meeting in Gothenburg in 1839 he traveled with his professor F. Liebmann around Västergötland and Östergötland and after the Nature Researcher meeting in Copenhagen in 1840 he traveled with Elias Fries around Skåne and Halland.

His health, however, sank, so to recover, he traveled through Germany, Austria and the Apennine Peninsula to Sicily. Despite the disease, he brought large amounts of collected plants from this journey. He returned to Copenhagen and worked in 1844 and participated in the Nordic Nature Research Meeting in Christiania the same year.

In 1845 he was employed as a botanist on the Galathea expedition. He attended the expedition until it reached Pulo Penang in the present Malaysia. Both because of health problems and because of dissatisfaction with the conditions on board, Kamphøvener stood off and went home. As a botanist at the Galathea expedition, he was replaced by Ferdinand Didrichsen. Fighters arrived in Køge on June 26, 1846 and died on July 20, 1846.

Carl Friedrich Schmidt (1811 – 1890)

C.F. Schmidt was a German botanical artist. He was a specialist in spermatophytes and was a renowned botanical artist (akademischer Künstler zu Berlin) and lithographer who illustrated many of the Germanic botanical works of the 19th century.

In collaboration with Otto Karl Berg (1815-1866), professor of pharmaceutical botany at Berlin University, Schmidt was published in Darstellung und Beschreibung in den Pharmacopoea Sämtliche Borussica offizinellen Gewächse aufgeführten (1853). Publisher: Arthur Felix, Leipzig Schmidt both drew and lithographed the plates. Benjamin Daydon Jackson describes this work, a survey of plants used in the Prussian pharmacopoeia, as "A thoroughly good book, probably the very best of its class; both in text and illustrations".

Publisher: Gera-Untermhaus : F.E. Köhler, [1883-1914]. Medizinal Pflanzen was published in 1887 in Gera, an east-central German city south of Leipzig. The set of four volumes was a noteworthy achievement and included plants of medicinal interest from several European nations. It was described by Sitwell and Blunt as "From the botanical standpoint the finest and most useful series of illustrations of medicinal plants.

Köhler's Medizinal Pflanzen was edited by Gustav Pabst, a German botanist. The remarkable feature of the publication is its nearly 300 finely detailed illustrations, expertly drawn by the artists L. Müeller and C.F. Schmidt, which were skillfully rendered by K. Gunther in chromolithography. Chromolithography is the process of rendering images on stone or zinc plates, then inking them with color inks to yield color pictures.

Ernst Ferdinand Nolte (1791 - 1875)

Nolte was a German botanist. He was son-in-law to chemist Christoph Heinrich Pfaff (1773–1852).

After duties as a pharmacy apprentice in Goslar, he studied medicine at the University of Göttingen. While a student, he engaged in frequent botanical excursions throughout northern Germany. In 1817 he finished his studies at Göttingen, and later came under the influence of Danish botanist Jens Wilken Hornemann (1770–1841). From 1821 to 1823 he conducted botanical investigations in Lauenburg and the "Elbe Duchies", later taking scientific excursions to Zealand, Funen, Jutland and islands off both coasts of the Schleswig-Holstein mainland.

From 1826 to 1873 he was a professor of botany at the University of Kiel, as well as director of its botanical garden. He was an instructor to Ferdinand von Mueller (1825–1896), who would later be known for his botanical work in Australia.

The plant genus Noltea from the family Rhamnaceae is named in his honor, as is Zostera noltei, a species of seagrass (named by Jens Wilken Hornemann, 1832).

He made significant contributions to the botanical atlas Flora Danica, and was the author of the following publications:

  • Botanische Bemerkungen über Stratiotes und Sagittaria, 1825
  • Novitiæ floræ Holsaticæ : sive supplementum alterum Primitiarum floræ Holsaticæ G. H. Weberi, 1826
  • Index seminum horti botanici Kiliensis, c. 1836–41.
