The author of this article commemorates fifty years of the journal Communication & langages. He comments on the meaning of this title, whose terms are linked by an ampersand (&) and relates the reasons why this anniversary issue is dedicated to Gérard Blanchard, a professional and theorist who worked for the journal for over twenty-five years. Emmanuël Souchier invites us to discover, or rediscover, one of the great authors in the field of Information and Communication Science. He then moves on to discuss the ritual virtues of an anniversary issue and highlights the interest of coming back to the original topics dealt with by Communication & langages (graphic design, typography, and so on) while emphasizing the demanding theoretical and scientific level of a leading academic journal in social science and humanities. He then concludes on the need for passing on knowledge, know-how, and attitude between generations of researchers within the editorial and academic environment of the journal Communication & langages.
