REPP, THORLEIF GUDMUNDSSON, a learned author, was born as Reykiadal in Iceland in 1794, and received his education at the university of Copenhagen. He was known in Britain between 1825 and 1837 as a foreigner of great acquirements. The curators of the Advocates' Library had brought him over to Edinburgh to be their sub-librarian. His acquaintance with the modern languages and with Hebrew and Arabic was extensive. Nor was he incompetent to write English. In 1832 he published A Historical Treatise on Trial by Jury, Wager of Law, and other co-ordinate Forensic Institutions formerly in use in Scandinavia and in Iceland; in 1833 he wrote an article on the Advocates' Library for the Penny Cyclopædia; and about the same he contributed to the literature of the country several translations from the German and Italian. After his return to Copenhagen in 1837, Repp continued his literary labours. Among other works, he wrote a pamphlet in Danish, entitled Dano-Hungarian Discoveries, Copenhagen, 1843; and compiled, in conjunction with Ferrall, a Danish and English Dictionary, 12mo, Copenhagen, 1846. He died in 1858.
