Ferdinand Christian Gustav Arnold

Ferdinand Christian Gustav Arnold (24 February 1828 – 8 August 1901)[1] was a German lichenologist and taxonomist born in Ansbach, Bavaria.

Even as a high school student he showed an active interest in botany: "Ich und August Gattinger ... durchstreiften von November 1846 bis zum Spätherbst 1847, Pflanzen sammelnd, die Landschaft von München nach allen Richtungen."

("August Gattinger and I … roamed across the landscape of Munich from November 1846 up to the late autumn 1847, collecting plants, in all directions.").

Additionally he was a student of botanists Carl Friedrich Philipp von Martius (1794–1868) and Otto Sendtner (1813–1859), and his spare time was devoted to floristics and classification of plants and fungi.
