H. Herzer was a German steel and copper engraver active in the 1830s–1840s. His creative work coincided with the heyday of steel engraving in Europe, a technique widely used for book illustrations and topographical prints featuring landmarks from various countries.
The engraver's signature appears on topographical prints including:
-
View of the Kremlin in Moscow — an engraving published in Philadelphia by the North American Bibliographic Institution (N. A. Bibl. inst.)
-
"The Golden Tower in Seville" (Der Goldne Turm in Sevilla) — dated 1837
Based on the publication locations of his works (Moscow, Seville), Herzer engraved after drawings by other artists or originals, creating views of European cities for the international market. His engravings are characterized by meticulous attention to architectural detail and the fine lines typical of steel engraving technique.
Herzer's works were printed not only in Europe but also in the United States, where publishers purchased original steel plates to produce editions for the American market.
