Roger Gray worked as a senior lecturer in Statistics at Heriot-Watt University for 40 years.
Although he retired in September 2007, Mr Gray still worked part-time at the university taking classes for mainly final year and postgraduate students.
He also worked with the Scottish Government, providing refresher courses for civil servants working in the statistics department.
He was a popular teacher who was named the Graduating Students’ Best Teacher in the School in 2007 and awarded the University Prize for Excellence in Teaching in 2003.
His career began after he graduated from the University of St Andrews with a degree in Pure Mathematics in 1968 and joined the staff at Heriot-Watt straight away. He was one the first lecturers in the Department of Actuarial Mathematics and Statistics when it started in 1972.
A member of the Scottish Arts Club and Edinburgh Festival Society, he lists his interests as Wagner, opera and travelling on the university’s website. Mr Gray also writes that he is working on a book with Dr Susan Pitts from the University of Cambridge that is due to be published later this year.
