Karl Müller (1813-1894) published two standard works, Fragmenta Historicorum Graecorum and Geographi Graeci Minores, which have never been superseded, but very little is known about his life, and he is frequently confused with Carl Otfried Müller, another great German classicist of the nineteenth century. Born near Hannover, Karl and his brother and collaborator Theodor both studied at the University of Göttingen, but both left Germany in 1839, probably for political reasons. They moved to Paris, where Fragmenta was produced in partnership with the printer-publisher Ambroise Firmin-Didot. It covers histories which have been lost, but of which fragments survive in other works. Volume 2, published in Paris in 1843, contains the surviving histories of Diorodus Siculus, Polybius, and Dionysius of Halicarnassus.
