De Wit (1629 ca.-1706) was a mapmaker and mapseller who was born in Gouda but who worked and died in Amsterdam. From the 1660s onward, he published atlases with a variety of maps. After Frederik’s death in 1706, most of the plates went to Pieter Mortier, whose firm eventually became Covens & Mortier, one of the biggest cartography houses of the eighteenth century.
