Paul Kretschmer (May 2, 1866 – March 9, 1956) was a German linguist who studied the earliest history and interrelations of the Indo-European languages and showed how they were influenced by non-Indo-European languages, such as Etruscan.
His epochal study of pre-Greek elements in ancient Greek was his Einleitung in die Geschichte der griechischen Sprache (1896; 'Introduction to the History of the Greek Language'). Comparing Greek place names with their foreign counterparts in ancient Anatolia, he concluded that a non-Greek, Mediterranean culture had preceded the Greeks there, leaving extensive linguistic traces. The discoveries of the archaeologist Sir Arthur Evans at Knossos, Crete, around 1900 tended to confirm Kretschmer's views.
