It is always difficult to date the beginning of a new point of view, a new theory and method, within a given research area, but although Denmark has had a great philological and linguistic tradition (in the nineteenth century, for example, Rask, Madvig, Verner, Thomsen, in the twentieth century Pedersen, Jespersen, and so on), semiotics is associated with a turning point in Danish linguistics in the 1930s marked by the formation of the Linguistic Circle of Copenhagen (Le Cercle Linguistique de Copenhague) and the publication of the linguistic journal Acta Linguistica Hafniensia (1 [a]. 1939- ). The editors of the journal were the Romance philologist and linguist Viggo Brøndal and the comparative philologist and linguist Louis Hjelmslev.
