Johann Jakob Bernhardi
Johann Jakob Bernhardi (1 September 1774, in Erfurt – 13 May 1850, in Erfurt) was a German doctor and botanist. Biography. Johann J. Bernhardi studied Medicine and Botany at the University of Erfurt, and after graduation practiced medicine for a time in his native city. In 1799 he was named director of the botanical garden at "Gartenstraße", and in 1809 was appointed professor of botany, zoology, mineralogy and materia medica at the university. He served as director of the botanical garden until his death in 1850, being buried in the central avenue of this botanical garden. Throughout his  life thanks to acquisitions and interchanges with other botanists, he assembled a considerable herbarium of 60,000 plants with specimens from North America, South America, Asia, and Africa. After his death this herbarium did not remain in Germany but due to the efforts of George Engelmann, who, in 1857, shortly after the death of Bernhardi bought the complete herbarium for the amount of 600 dollars for Henry Shaw, founder of the Botanical Garden of Missouri in the U.S.A., forms the nucleus of the collection and the initial museum of this Botanical Garden (at the moment the "Missouri Botanical Garden herbarium" contains  over 6.2 million specimens and the library over 120,000 volumes). Johann J. Bernhardi studied and described several species of orchids, including "Epipactis atrorubens". He described a species of rose without thorns, "Rosa × francofurtana", found in the garden of the house of Johann Wolfgang von Goethe in Weimar. The genus "Bernhardia" (family Psilotaceae) is named in his honor. He was editor of the "Thüringischen Gartenzeitung" (Thuringian garden newspaper) and the "Allgemeinen deutschen Gartenmagazin" (General German garden magazine). The thoroughfare, "Jacob-Bernhardi-Straße" in Erfurt, is named in his honor.
