We are deeply saddened to inform you of the death of Ian Maddieson. Ian passed away on 2 February 2025 already. His influential work on the typology of sounds, notably the UCLA Phonological Inventory of Languages (UPSID), has significantly advanced our understanding of linguistic diversity. A respected field researcher and theorist, Maddieson contributed significantly to our knowledge of language universals and phonological theory.

His services to the International Phonetic Association were highly valued and will never be forgotten. Ian was a lifetime IPA member, served on both the IPA Council and the Executive Council, and last but not least he was also an editor of JIPA. He leaves behind a rich scholarly legacy.

We will miss him very much!
