Scottish classical scholar, born in October 1674, at Raggal, Banffshire, where his father was a farmer. He was educated at Aberdeen University, and through the influence of Dr. Archibald Pitcairne he was made assistant in the Advocates Library, Edinburgh. His chief writings at this period were editions of Florence Wilsons De Animi Tranquillitate Dialogus (1707), and the Cantici Solomonis Paraphrasis Poetica (1709) of Arthur Johnston (15871641), editor of the Deliciae Poetarum Scotorum. On the death of Dr. Pitcairne he edited his friends Latin verses, and arranged for the sale of his valuable library to Peter the Great of Russia. In 1714 he published Rudiments of the Latin Tongue, which was long used in Scottish schools. In 1715 he edited, with notes and annotations, the works of George Buchanan in two volumes folio. As Ruddiman was a Jacobite, the liberal views of Buchanan seemed to him to call for frequent censure. A society of scholars was formed in Edinburgh to vindicate that incomparably learned and pious author from the calumnies of Mr. Thomas Ruddiman; but Ruddimans remains the standard edition, though George Logan, John Love, John Man and others attacked him with great vehemence. He founded (1715) a successful printing business, and in 1728 was appointed printer to the university. He acquired the Caledonian Mercury in 1729, and in 1730 was appointed keeper of the Advocates Library, resigning in 1752. He died in Edinburgh, on the 19th of January 1757.
Besides the works mentioned, the following writings of Ruddiman deserve notice: An edition of Gavin Douglass Aeneid of Virgil (1710); the editing and completion of Andersons Selectus Diplomatum et Numismatum Scotiae Thesaurus (1739); Catalogue of the Advocates Library (173342); and a famous edition of Livy (1751). He also helped Joseph Ames with the Typographical Antiquities. Ruddiman was for many years the representative scholar of Scotland. Writing in 1766, Dr. Johnson, after reproving Boswell for some bad Latin, significantly addsRuddiman is dead. When Boswell proposed to write Ruddimans life, I should take pleasure in helping you to do honour to him, said Johnson.
