It will feature the Leslie Seiffert Lecture, delivered by Professor Emeritus Richard Hudson of University College London. The Henry Sweet Society was founded in February 1984 with the aim of promoting and encouraging the study of the history of all branches of linguistic thought, theoretical and applied, and including non-European traditions. Its fields of interest include the history both of the major subject areas of linguistics and also of more specialised topics, such as writing systems, literacy, rhetoric, and the application of linguistic ideas within professional and technical fields. It also publishes the biannual journal, Language and History. For further details and booking forms see the Society’s website, www.henrysweet.org
