At the beginning of the seventeenth century Amsterdam was becoming one of the wealthiest trading cities in Europe, the base of the Dutch East India Company and a centre of banking and the diamond trade, its people noted for their intellectual skills and splendid craftsmanship.

At this propitious time in the history of the Northern Provinces, Willem Janszoon Blaeu, who was born at Alkmaar in 1571 and trained in astronomy and the sciences by Tycho Brahe, the celebrated Danish astronomer, founded a business in Amsterdam in 1599 as a globe and instrument maker.

It was not long before the business expanded, publishing maps, topographical works and books of sea charts as well as constructing globes.

His most notable early work was a globe 1598, map of Holland (1604), a fine World Map (1605-06) and Het Licht der Zeevaerdt (The Light of Navigation), a marine atlas, which went through many editions in different languages and under a variety of titles.

At the same time Blaeu was planning a major atlas intended to include the most up-to-date maps of the whole of the known world but progress on so vast a project was slow and not until he bought between 30 and 40 plates of the Mercator Atlas from Jodocus Hondius II to add to his own collection was he able to publish, in 1630, a 60-map volume with the title Atlantis Appendix.
It was another five years before the first two volumes of his planned world atlas, Atlas Novus or the Theatrum Orbis Terrarum were issued. About this time he was appointed Hydrographer to the East India Company.

It ought to be mentioned here that there is often confusion between the elder Blaeu and his rival Jan Jansson (Johannes Janssonius). Up to about 1619 Blaeu often signed his works Guilielmus Janssonius or Willems Jans Zoon but after that time he seems to have decided on Guilielmus or G. Blaeu.

In 1638 Blaeu died and the business passed into the hands of his sons, Joan and Cornelis, who continued and expanded their father's ambitious plans.
