I expect that there are people reading this who are completely unaware of Jim Madden's part in creating PDMS. The first idea of developing what eventually became PDMS came when Jim met Mike Leesley of the CADCentre (now known as Aveva) at a conference and they exchanged ideas about what might be done for pipework design on computer. That was in 1972 or early 73. I first heard about it from Jim in 1973. Jim's hope was that my employer, British Steel, might be interested, but they were not. Jim then offered me a Job working on Compaid and PDMS (and the drawing-board when work was scarce) in early 1974.
