Johannes VAN KEULEN

1654 - 1715

Johannes van Keulen was baptised on January 8, 1654, in Amsterdam, and died there in 1715. Born into a family without professional ties to cartography, he originally established himself in Amsterdam in 1678 as a bookbinder and bookseller rather than a trained chart maker. Recognising a commercial opportunity as earlier prominent 17^th-century Dutch map publishing firms were closing down, Van Keulen founded a cartographic dynasty that would dominate Dutch maritime publishing for over two centuries. Not formally educated in cartography, he relied on strategic collaborations to build his business, most notably partnering with the Amsterdam mathematician, surveyor, and navigation teacher Claes Janszoon Vooght, who calculated and compiled the geographic data for the firm’s early publications.

Van Keulen played a pivotal role in establishing Amsterdam as the leading European centre for marine cartography during the late 17^th century. In 1680, he secured a crucial monopoly patent from the States of Holland and West Friesland, granting him the exclusive right to print and publish maritime atlases and pilot guides. While Van Keulen managed the commercial and publishing logistics, he integrated technical precision and artistry into his works by combining Vooght’s hydrographic compilations with striking illustrations by the prominent engraver Jan Luyken. He further expanded his operational foundation by acquiring the printing plates and copperplate stock of rival chart maker Hendrik Doncker in 1693. His landmark publications include De Groote Nieuwe Vermeerderde Zee-Atlas ofte Water-Werelt (1680), a highly comprehensive and continually updated maritime atlas, and De Nieuwe Groote Lichtende Zee-Fakkel (1681-1684), a monumental five-volume pilot guide that merged detailed coastal charts with written sailing directions. The business and its extensive stock were passed down through successive generations, starting with his son, Gerard van Keulen, who later became the hydrographer to the Dutch East India Company.

Johannes van Keulen is remembered as the enterprising founder of a premier maritime publishing dynasty whose expansive sea atlases and pilot guides defined the standards of commercial navigation and hydrographic printing for generations of European mariners.
