George Dalgarno

George Dalgarno (1626 - 1687) was a Scottish linguist and philosopher.

He spent most of his life teaching grammar at a private school in Oxford, despite which he was in contact with the main Oxford intellectuals of the time, such as Wilkins, Lodwick and Robert Boyle.

He was the author of a synthetic language that he presented in his book Ars Signorum (1661), as well as the work Didascalocophus (1680).

According to several researchers (such as William F. Friedman, Tiltman and others), the Voynich Manuscript appears to have been written in some type of synthetic language such as that described by Dalgarno.
