Life and career

Maddieson was born in Watford, England, on 1 September 1942. After receiving a M.A. degree from SOAS, he taught for four years (1968-1971) at the University of Ibadan in Nigeria before taking a one-year position at Indiana University. Research positions on projects at UCLA and Stanford followed. He completed a Ph.D. in linguistics at UCLA in 1977, with a dissertation entitled Universals of Tone: Six Studies. He remained at UCLA as adjunct faculty in phonetics until the end of 1999, doing research and occasionally teaching. He then moved to the University of California, Berkeley, where he remained until retiring and moving to Albuquerque in 2006.

He was a prolific field phonetician. His pioneering and widely cited books, Patterns of Sounds and The Sounds of the World's Languages (with Peter Ladefoged), helped define the fields of contemporary linguistic phonetics and phonological typology. He contributed to a number of online typological databases. For example, he wrote several chapters of WALS, and he worked with researchers at the Laboratoire Dynamique du Langage in Lyon, France, to develop an online database of the sounds of languages around the world, intended to update UPSID.

Maddieson died on 2 February 2025, in Albuquerque, New Mexico, at the age of 82.
