German naturalist and explorer (1769-1859) who wrote Kosmos, a massive five-volume study which attempted to unify the various branches of man's knowledge. Rare oversized 12 x 15 engraved portrait of Alexander von Humboldt by C. Bazin after F. P. S. Gérard, neatly inscribed in the lower right corner to private secretary Dr. Buschmann, in the remembrance of his brother Wilhelm von Humboldt, and signed below, "A. v. Humboldt, Berlin, Mai 1843.". In very good to fine condition, with staining and slight damage to the lower left corner which could mostly be matted out if desired. Johann Karl Eduard Buschmann was a German philologist who worked closely with Wilhelm and Alexander von Humboldt, and was employed to prepare the original manuscript of Alexander's ambitious Kosmos (1845-1859). Humboldt is incredibly rare in portraits of this size, and this piece boasts outstanding personal and professional associations.
