Philipp Cluver (1580 - 1623) who Latinized his name as Philippus Cluverianus in the fashion of the time, was born in Gdansk; he travelled widely in Europe before settling in the tolerant atmosphere of Leiden, where he studied law.

Cluver was an antiquary, who was given a special appointment at Leiden University as geographer and put in charge of the university's library, but his life's project, it developed, was a general study of the geography of Antiquity, based not only on classical literary sources, but—and this was his contribution—supplemented by wide travels and local inspections. He became virtually the founder of historical geography.

His first work, in 1611, concerning the lower reaches of the Rhine and its tribal inhabitants in Roman times (Commentarius de tribus Rheni alveis, et ostiis; item. De Quinque populis quondam accolis; scilicet de Toxandris, Batavis, Caninefatibus, Frisiis, ac Marsacis) touched a source of national pride among the Seventeen Provinces, for the Dutch were enjoying an eight years' truce in their Eighty Year War of liberation.

His Germaniae antiquae libri tres (Leiden, 1616) depends on Tacitus and other Latin authors. A volume on the antiquities of Sicily, with notes on Sardinia and Corsica (Sicilia Antiqua cum minoribus insulis ei adjacentibus item Sardinia et Corsica), published at Leiden by Louis Elsevier in 1619, is a useful source, with many reference from writers of Antiquity and maps that are often detached and sold to map collectors. His Introductio in universam geographiam (published in 1624) became a standard geographical textbook.

He was also a prolific a writer on mathematical and theological subjects. He is remembered by collectors and historians of cartography for his edition of Ptolemy's Geographia (based on Mercator's edition of 1578) and for miniature atlases that were reprinted for most of the 17th century. Many of his maps were etched for him by Petrus Bertius.
