Carl (Karl) Georg Ludwig Theodor Herwig Joseph Robert (8 March 1850 – 17 January 1922) was a German classical philologist and archaeologist.

He began his studies of ancient philology and archaeology at the University of Bonn, where he was a student of Otto Jahn, Reinhard Stradonitz, and Anton Springer.

Afterwards, he resumed his studies at the University of Berlin under Theodor Mommsen, Adolf Kirchhoff and Ulrich von Wilamowitz-Moellendorff.

[2][3] As a classical scholar, he preferred a close association between the disciplines of archaeology and philology, while downplaying the art historical approach.

[1] For many years, he was editor of the journal Hermes, and was the author of a highly regarded revision of Ludwig Preller's Griechische Mythologie.
