1728 Van Keulen Map of Pisang Islands on the West Coast of Sumatra, Indonesia

Johannis Van Keulen (1654 – 1715) was a Dutch cartographer active in Amsterdam during the late 17th century. Keulen was the son of Lucas van Keulen. Keulen's firm, ‘In de Gekroonde Lootsman' (In the Crowned Pilot), was founded in 1678 and registered with the Amsterdam bookseller's guild as 'Cross staff-maker and bookseller'. The cross-staff is a nautical instrument used to determine latitude. Two years later, in 1680, they obtained a patent from the States General of Holland and West Friesland to publish nautical charts and atlases. Together with his partner, the cartographer Claes Janz Vooght, Van Keulen published numerous atlases and nautical charts, including the Zee Atlas and Nieuwe Lichtende Zee-Fakkel. The term, Zee-Fakkel translates to 'Sea Torch.' It was a massive five volume atlas containing more than 130 nautical charts. The Zee-Fakkel established the Van Keulen firm as the pre-eminent maker of Dutch sea charts in the late 17th and early 18th century. In 1714, one year before Johannis Van Keulen death, his son, Gerard van Keulen (1678 - 1726), took charge. Gerard continued to update and republish the Zee-Fakkel until his own death in 1726. The firm was later passed on to Gerard's son, Johannes II Van Keulen (1704 - 1755), who significantly updated the atlas, especially with regard to Asia, issuing the 1753 4th Volume, known as the 'Secret Atlas'. The final editions of the atlas were published by Gerard Hulst van Keulen (1733 - 1801), Joannes II's son. The final true Van Keulen edition of the Zee-Fakkel was published posthumously in 1803. It is noteworthy that though ostensibly controlled by the Van Keulen men, it was the Van Keulen widows who maintained and managed the firm in the periods following their husbands' deaths. After the death of Gerard Hulst Van Keulen's son, Johannes Hulst Van Keulen, ownership of the family plates and business fell into the hands of the Swart family who continued to publish until the company closed its doors 1885, ending cartographic legacy spanning nearly 207 years.
