Rasmus Rask

Rasmus Kristian Rask (Danish: [ˈʁasmus ˈkʰʁæstjæn ˈʁask]; born Rasmus Christian Nielsen Rasch; 22 November 1787 – 14 November 1832) was a Danish linguist and philologist. He wrote several grammars and worked on comparative phonology and morphology. Rask traveled extensively to study languages, first to Iceland, where he wrote the first grammar of Icelandic, and later to Russia, Persia, India, and Ceylon (now Sri Lanka). Shortly before his death, he was hired as professor of Eastern languages at the University of Copenhagen. Rask is especially known for his contributions to comparative linguistics, including an early formulation of what would later be known as Grimm's Law.
