Edward Thomas Copson FRSE (21 August 1901 – 16 February 1980) was a British mathematician who contributed widely to the development of mathematics at the University of St Andrews, serving as Regius Professor of Mathematics amongst other positions.
[1][2] He married Beatrice, the elder daughter of E. T. Whittaker,[3] and moved to the University of St Andrews where he was Regius Professor of Mathematics, and later dean of science, then Master of the United College.
[citation needed] He was elected a Fellow of the Royal Society of Edinburgh in 1924, his proposers being Sir Edmund Taylor Whittaker, Herbert Stanley Allen, Bevan Braithwaite Baker and A. Crichton Mitchell.
He was awarded the Keith Medal by the Royal Society of Edinburgh in 1942 for his research in mathematics.
[5] Copson's primary focus was in classical analysis, asymptotic expansions, differential and integral equations, and applications to problems in theoretical physics.
