He was awarded a PhD in 1944 for research on the Numerical Integration of Partial Differential Equations.〔http://www.chilton-computing.org.uk/acl/associates/permanent/howlett.htm quoting an article published in "Quest" in 1971〕 He worked with the research department of the LMS Railway from 1935 to 1940.〔 He often described his relief when his calculations of the performance of a new braking system were tested successfully on a real steam locomotive complete with sceptical crew.〔 During the war he worked in research establishments on numerical analysis, under experts including Douglas Hartree, and using equipment such as early mechanical differential analyzers.〔 This was applied to various problems including the atomic bomb project code-named Tube Alloys.〔Obituary, ICL Systems Journal, vol 14 issue 1, 1999〕 In 1948 he became head of the Computing Section in Theoretical Physics Division, AERE Harwell. He worked on many of the early reactor projects.〔 In 1966 he was elected Fellow of St Cross College, Oxford. He was a member of the Institution of Electrical Engineers, a Fellow of the Royal Statistical Society and a Fellow of the Institute of Mathematics and its Applications.〔 He was awarded the CBE in the New Years Honours List of 1969.〔 He was married to Joan, with whom he had five children. He enjoyed a wide range of musical and artistic activities, was a keen Scottish country dancer, took part in amateur dramatics, and enjoyed cycling and hill-walking.
