William Marlow Evans (c1907-1969)
1969 Obituary 
Mr William Marlow Evans (Member) died recently aged 62. Educated in Birmingham, William Evans became a pupil at the Lanchester Motor Co in 1924. He joined the Engine Division of the Bristol Aeroplane Co. in 1929 as Technical Assistant and Quality Manager. Always interested in engine testing and development, Evans became Experimental Manager and later Experimental Engineer in control of all ground and flight development of the Bristol series of aero engines. This was at a time of intense activity during the war.
In 1945 William Evans joined the Air Registration Board as Chief Engineer and was responsible for the approval of all power plants operating in aircraft on the British Register. He travelled extensively in the course of his duties and was universally respected.
`Bill' Evans could be forthright in manner but his judgement, based on a vast practical experience, was always fair and constructive. Over the years he made a considerable contribution to the success of British aero engine development and reliability. He joined the Institution of Automobile Engineers and transferred to the AD in 1947.
