Evelyn Martin Lansdowne Beale FRS (8 September 1928 - 23 December 1985) was an  applied mathematician and statistician who was one of the pioneers of mathematical programming.
He was educated at
Winchester College and at Trinity College, Cambridge, graduating with First Class Honours in Mathematics in 1949 and gaining a Diploma in Mathematical Statistics in 1950.  He then joined the Mathematics Group at the UK  Admiralty Research Laboratory, working under Stephen Vajda for 11 years, except for a leave of absence in 1957/58 to assist the Statistical Techniques Research Group at Princeton University.    In 1955 he extended  George Dantzig's Simplex Algorithm to minimise a quadratic function. 
In 1961 he became a founder member of a computer services company C.E.I.R (UK), which
BP bought and renamed Scicon, and in 1967 he became Visiting Professor at Imperial College, London.   
Beale was Chairman of the
Mathematical Programming Society from 1974 to 1976, Vice-President of the Royal Statistical Society from 1978 to 1980, a Fellow of the British Computer Society, and a member of the International Statistical Institute. In 1979, he was elected a Fellow of the Royal Society "for his applications of mathematical and statistical techniques to industrial problems and for his contributions to the theory of mathematical programming", and he was elected to the Council of the Royal Society in 1984. He was awarded the Silver Medal of the Operational Research Society in 1980, and became Vice-President of the  Institute of Mathematics and its Applications. He was also non-executive Chairman of Beale International Technology.  suggested that he "used his blend of theory and state-of-the-art practice to encourage several generations of young mathematicians and computer scientists," and that his "many papers and his seminal book The Times Mathematical Programming in Practice were major influences in their field, with their succinctness and clarity." 
FRS memoir mentioned his "extraordinary skill" and "substantial contributions to knowledge". 
Beale produced over 100 scholarly papers
and two books:
Beale was a son of Muriel Rebecca Beale
OBE, who was a descendant of General Sir John Slade, a grandniece of Edmond Warre, and a first cousin of Madelaine Slade. He was survived by his wife and three children.
