Early life and education

Churchhouse was born on 30 December 1927 in Higher Blackley, Manchester. The son of Robert Francis, a laboratory assistant, and Agnes Churchhouse (née Howard), a cotton mill worker. Churchhouse grew up into a Roman Catholic family. He attended St Clare's RC Primary School, and then St Bede's College, Manchester from 1939 to 1946. He pursued an undergraduate education in mathematics at Manchester University, where he was taught by both Max Newman and Alan Turing, both now famous for their code breaking work at Bletchley Park in WW2. Churchhouse graduated with a first class honours degree and subsequently received an award to undertake a PhD in Number Theory at Trinity Hall, Cambridge under the supervision of Professor Louis J. Mordell. His time at Cambridge brought him into contact with other ex-Bletchley mathematicians.[1]

Career

In 1952, for his national service, Churchhouse joined the Royal Navy Scientific Service, and then the Government Communications Headquarters (GCHQ) where he worked for 11 years in London, Cheltenham, and at the UK's embassy in Washington. The GCHQ was interested in his work in number theory, and he was initially interviewed in May 1952. During his time at the GCHQ, he worked with Hugh Alexander and Jack Good both of whom had also worked at Bletchley Park on the breaking of the Enigma code. In 1962, he was appointed head of programming at the Atlas Computer Laboratory at Harwell where he worked on the Atlas I supercomputer until 1971.[2]

Churchhouse left Atlas in 1971 and joined Cardiff University as an Inaugural Professor and head of the newly created Department of Computing Mathematics. He was also the Director of the Cardiff University Computer Centre for the early part of his tenure.[1][3][4]

In 1965, Bob was asked to serve on the Flowers Committee[5] responsible for the provision of computers to Universities and Research Councils and was subsequently asked to serve on the follow-up Computer Board. He chaired the Computer Board from 1979 to 1982 and was subsequently awarded a CBE for his services.

As a lifelong Catholic, he helped reorganise the Catholic Secondary Schools in Cardiff as well as serving on the Board of Governors of Saint David's Sixth Form College for 15 years. He was recognized for his service with an Papal Knighthood (KSG) in 1988.[3]
