University College, London professor of architecture and archeaologist; involved in the debates regarding the polychromy of Greek architecture. Donaldson was part of a committee including Jacques-Ignace Hittorff and C. R. Cockerell, which met between 1836-1837 to determine whether the Elgin Marbles and other Greek statuary in the British Museum had originally been colored. They concluded that they had not, (their findings appear in the Transactions of the Royal Institute of British Architects for1842), despite Cockerell's knowledge-and perhaps more--that other sculpture had.
