Geoff Henderson wrote the history of the world’s first production system (shop-floor real-time transaction reporting system) for steel making at the Steel Company of Wales 1965-73. Geoff was the leader of the systems analysis and implementation team. His paper is a hugely important record of the endeavour – from a systems design and implementation viewpoint and with an eye to the social history of its developers and users. Geoff and the team pioneered in many ways: in specialist hardware, in software and even in labour relations. Today he welcomed Tom Abram to his home in Wales to talk about his life and career.
