Richard Hudson (usually known as Dick Hudson) is a British linguist. He was born in 1939 and lived most of his life in England (with three years in New Zealand 1945-8). He turned into a linguist via Loughborough Grammar School in Leicestershire (1948-58), Corpus Christi College Cambridge (1958-61) and the School of Oriental and African Studies (PhD 1961-4). He worked with Michael Halliday as research assistant on two projects at University College London: on the grammar of scientific English with Rodney Huddleston (1964-7), and on Linguistics and English Teaching (1967-70). In 1970, he was appointed lecturer at UCL, where he spent the rest of his working life, mostly in the Department of Phonetics and Linguistics, retiring in 2004. His main research achievement is a general theory of language structure called word grammar, but he has also worked hard to build bridges between academic linguistics and teaching of (and about) language in UK schools.
