Palaeoanthropologists Eugene Dubois (centre, standing) and Sir Arthur Keith (top left), photographed at Cambridge in 1898. In 1892-3 Dubois collected the skull cap & thigh bone of a hominid fossil, which he named Pithecanthropus erectus, meaning erect ape-man, later renamed Homo erectus. More popularly called Java Man, from its origins in the sands of the Solo River, Central Java, Homo erectus was the most widespread and longest-surviving of all the fossil hominids. Keith et al refused to endorse Dubois' assertion of Homo erectus as a link between apes & humans. A piqued Dubois is reported to have hidden the bones under his dining-room floorboards.
