Louis Hjelmslev

Louis Trolle Hjelmslev was a Danish linguist whose ideas formed the basis of the Copenhagen School of linguistics. Born into an academic family, Hjelmslev studied comparative linguistics in Copenhagen, Prague and Paris. In 1931, he founded the Cercle Linguistique de Copenhague. Together with Hans Jørgen Uldall he developed a structuralist theory of language which he called glossematics, which further developed the semiotic theory of Ferdinand de Saussure. Glossematics as a theory of language is characterized by a high degree of formalism. It is interested in describing the formal and semantic characteristics of language in separation from sociology, psychology or neurobiology, and has a high degree of logical rigour. Hjelmslev regarded linguistics — or glossematics — as a formal science. He was the inventor of formal linguistics. Hjelmslev's theory became widely influential in structural and functional grammar, and in semiotics.
