Philipp Cluver (1580 – 1622) was born in Danzig and studied at Leyden and Oxford. An influential geographer, he published numerous pieces the most famous of which was Introductonius. The first edition of this popular geography book was published without maps. Many later editions with maps from several sets of plates followed his death and were published throughout the 17th and 18th Centuries. Most of the surviving maps attributed to him today are from Introductonius.
