My colleague Dai Edwards, who has died aged 92, was one of a small group of engineers who designed the world’s first commercially available computer. He went on to help design other high-performance computers, each the product of fruitful collaboration between academia and industry.
David Beverley George Edwards, known to colleagues as Dai, was born in Tonteg, South Wales. He was the only child of Cecilia (nee George) and William Edwards, who were both teachers. Dai went to Pontypridd boys’ intermediate school, leaving in 1945 with a state scholarship to study physics at Manchester University. Upon graduation, he joined Professor FC (Freddie) Williams’ electrical engineering group in September 1948.
