Sir Aubrey Fiennes Trotman-Dickenson (12 February 1926 – 11 November 2016) was a British chemist and academic administrator.

Trotman-Dickenson was born in Wilmslow, Cheshire on 12 February 1926. His father, Edward Newton Trotman-Dickenson was a cotton merchant and his mother was Violet Murray, née Nicoll. He attended Winchester College and continued to study Chemistry with a scholarship to Balliol College, Oxford in 1948.^[1]

He was Principal of the University of Wales Institute of Science and Technology (UWIST) from 1968 to 1988, and Principal of its successor, University of Wales College of Cardiff, from 1988 to 1993. He additionally served as the Vice-Chancellor of the University of Wales for three terms: 1975 to 1977, 1983 to 1985, and 1991 to 1993. He was previously a lecturer in chemistry at the University of Edinburgh, and Professor of Chemistry at University College of Wales, Aberystwyth.^[2][3][4][5]
