Dr Gardiner was one of the founder members of the UKMT in 1996. He was the central figure in British mathematics competitions before then. For many years he ran competitions and IMO preparation as a personal mission. He was instrumental in bringing together various activists under the UKMT umbrella, and continued to make a significant contribution to our activities. At the time of his death he was a member of the UKMT’s Board of Trustees.
Many members of our community will remember Tony with great fondness, especially for his heroic work in building the foundations for the modern and successful maths competition infrastructure in the UK. He was also well-known for patiently guiding young mathematicians along their path to mathematical maturity. He was also active in trying to shape the attitudes of young mathematics teachers.
Tony was a Reader in Mathematics and Mathematics Education at the University of Birmingham until his retirement. The World Federation of National Mathematics Competitions gave him a Paul Erdos Award in 1996 for his contributions to UK and international mathematical challenges and olympiads. In 2016 he received the Excellence in Mathematics Education Award.
Tony leaves a widow Gwyn and five children. We send them our sincere condolences on their sad loss which we all share.
