Until he retired, at the age of 80, he was a visiting professor to the Industrial Statistics Research Unit of the University of Newcastle-upon-Tyne and to the Universitat Politècnica de Catalunya.

There he found satisfaction in solving production problems, studied OR, mathematics, statistics and computing leading to an external degree from University College London.

When the laboratories closed he joined the medical faculty of University of Sheffield where he was statistician to a multi-centre study of cot death.

Greenfield's passion was to persuade all scientists and engineers to write, speak and present their work in language that other people understand well enough to use in some ways.

"Our national quality of life will be improved and secured if we can communicate the philosophy, as well as the methods, of statistics to engineers and others in the manufacturing and the service industries.

He has spread this passion by speaking in many cities across Europe from Tel Aviv, through Turin, Budapest, Ljubljana, Copenhagen, Brussels and London.

Tony was a member of the Longstone Local History Society, the Bakewell Photographic Circle, Writers in the Peak, the Hucklows Community Spirit, and the Parisot (Tarn-et-Garonne)/Hucklows Twinning Committee.
