A German archaeologist who excavated many important prehistoric and classical sites in the Greek world. He worked first under Ernst Curtius on the excavations of Olympia and then assisted Heinrich Schliemann on his third and fourth seasons at Troy, bringing to this work the careful digging and recording techniques worked out at Olympia. After Schliemann's death he continued work at Troy, then later worked on the Ionian island of Leukas, off the west coat of Greece which, contrary to most other authorities, he believed to be Homer's Ithaca, home of Odysseus.
