Waghenaer, Lucas Janszoon
c.1534-1606. Dutch pilot and cartographer. Based on his 25 years of experience as a pilot and opportunities to examine numerous rutters and manuscript charts, he was able to compile the first effective set of navigational charts published 1584-85 under the title Spiegel der Zeevaerdt or Mirror of the Sea. It covered the waters of the North Sea and the Baltic and included sailing directions. Translated into English in 1588. His charts became so popular in England that they were called "Waggoners."
