It is with regret and sadness that the recent death on July 15 of Associate Professor John Clark is noted. John was a long serving member of the Department having been appointed in 1970 and having retired in 2013, although he continued his research in retirement.
He was an internationally respected mathematician, publishing three books and over 30 papers mainly in his specialist subject of ring theory, a branch of algebra. He collaborated with fellow ring theorists around the world, spoke at numerous international conferences, including one in his honour to celebrate his 70th birthday, and supervised students at honours, masters and PhD level. He was a highly regarded teacher, lecturing at all levels in algebra and allied topics. He was also involved in administration: as an interim Head of Department in the mid 1980’s and at the university level, where he looked after the Diploma for Graduates for several years.
In recent years John bravely dealt with the onset of Parkinson’s disease and stoically carried on with his life. He was in the Intensive Care unit at Dunedin hospital for several weeks prior to his death. John had a great sense of humour and a delightful turn of phrase, always delivered with his special Scottish twinkle.
The Department expresses sincere condolences to his wife Austina, also a long serving member of the Department, and to his sons John and Alan and their families.
