1600-73 - ARNOLD COLOM (son) c. 1624-68
Jacob Colom was a printer, bookseller, chart and globe maker who set out to challenge the virtual monopoly held by W. J. Blaeu, then the only chart maker in Amsterdam. His Pilot Guide De Vyerighe Colom published in various formats and languages (with exotic tides) to meet the demands of the time was highly successful and forced Blaeu to revise and enlarge his existing chart books. In spite of Blaeu's efforts, Colom's Guide remained popular with seamen for many years and although the charts were issued in great quantity, they are now extremely rare.
