This alphabetical listing of more than 15,000 authors and their life-dates aims to be “universal” in the sense that it covers, as far as possible for the work of a single individual, all linguistic traditions from the earliest beginnings of reflection about the nature of language to the present. The volume is the fruit of the compiler's many years at the helm of Historiographia Linguistica: International Journal for the History of the Language Sciences (1973–). While biographical data may be regarded by some as irrelevant or incidental to the history of particular linguistic ideas, experience has proven the usefulness of such basic information. Many of us can think of misrepresentations of chronology where the life-dates of an author under discussion were either not known or were simply ignored. At its most extreme, such ignorance could result in statements asserting that Edward Sapir was a student of Benjamin Lee Whorf, and that the latter had influenced the former in developing the famous Weltanschauungstheorie.
