When he married the daughter of the cartographer Jodocus Hondius he also set up a business as book publisher in Amsterdam. His first map was published in 1616. Around 15 years later he set up a partnership with his brother in law Hondius add issued further editions of the Mercator/Hondius atlas. After his death in 1664, his heirs still have published several maps. Many of his plates have been acquired by Pieter Schenk and Gerard Valk.
