Henry John Roby (1830-), English classical scholar and writer on Roman law, was born at Tamworth on the 12th of August 1830. He was educated at St John's College, Cambridge (senior classic, 1853; fellow, 1854). From 1866 to 1868 he was professor of jurisprudence at University College, London, and from 1872 to 1874 commissioner of endowed schools. From 1890 to 1895 he was member of parliament in the Liberal interest for the Eccles division of Lancashire. The book by which he is perhaps best known is his Grammar of the Latin Language from Plautus to Suetonius, a storehouse of illustrative quotations from Latin literature, but his most important works deal with Roman law - Introduction to Justinian's Digest (1884) and Roman Private Law (1902).
