H. Klockhoff, also known as Hendrik Klockhoff, was an Amsterdam-based engraver active in the latter part of the 18th century, approximately between 1777 and 1798. He is known for his detailed engraving work on maps and views, including some of the earliest maps recognizing the newly independent United States. Klockhoff’s work is respected for its technical skill and contribution to Dutch cartographic traditions during this period. His engravings often appeared in atlases and geographical publications, and he was involved in producing finely engraved title pages and numerous views related to Dutch maritime and trade themes, reflecting the cartographic and artistic interests of his time.
