John M M Pinkerton
joined AMRE (TRE) at Worth in June 1940 from Cambridge after previously spending 4 or 5 weeks at the Dover
Chain Home station in August/September 1939. He first set up some posts to listen for German navigational beams then joined the
Chain Home Low (CHL) / Ground Control of Interception (GCI) team at Worth Matravers and worked on aerial measurements. He installed the 50cm aerial
Bill Penley had designed on the Dover CHL. He later worked on IFF (Indication
Friend or Foe) with Lord Bowden.
After the war he returned to Cambridge to research ultrasonic waves in
liquids and obtained a PhD. This led him to stored programme research for computing and
in 1949 he took up the post of project leader at Lyons that resulted in him designing and developing
one of the world's first business computer systems - the Lyons Electronic Office or 'LEO'.
He later joined ICL and continued working at the top level in the computer industry.
He was twice the President of the European Computer Manufacturer's Association and since his death on 22nd
December 1997 the IEE has honoured him by arranging an annual Pinkerton lecture.
