Ferdinand de Saussure (soʊˈsjʊər; fɛʁdinɑ̃ də sosyʁ; 26 November 1857 – 22 February 1913) was a Swiss linguist, semiotician and philosopher. His ideas laid a foundation for many significant developments in both linguistics and semiotics in the 20th century. He is widely considered one of the founders of 20th-century linguistics and one of two major founders (together with Charles Sanders Peirce) of semiotics, or semiology, as Saussure called it.
One of his translators, Roy Harris, summarized Saussure's contribution to linguistics and the study of "the whole range of human sciences. It is particularly marked in linguistics, philosophy, psychoanalysis, psychology, sociology and anthropology." Although they have undergone extension and critique over time, the dimensions of organization introduced by Saussure continue to inform contemporary approaches to the phenomenon of language. As Leonard Bloomfield stated after reviewing the Cours: "he has given us the theoretical basis for a science of human speech".
Saussure was born in Geneva in 1857. His father, Henri Louis Frédéric de Saussure, was a mineralogist, entomologist, and taxonomist. Saussure showed signs of considerable talent and intellectual ability as early as the age of fourteen. In the autumn of 1870, he began attending the Institution Martine (previously the Institution Lecoultre until 1969), in Geneva. There he lived with the family of a classmate, Elie David. Graduating at the top of class, Saussure expected to continue his studies at the Gymnase de Genève, but his father decided he was not mature enough at fourteen and a half, and sent him to the Collège de Genève instead. Saussure was not pleased, as he complained: "I entered the Collège de Genève, to waste a year there as completely as a year can be wasted."
After a year of studying Latin, Ancient Greek and Sanskrit and taking a variety of courses at the University of Geneva, he commenced graduate work at the University of Leipzig in 1876.
